SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to the Marine Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Folklife Studies

Smithsonian Studies in Air and Space

Smithsonian Studies in History and Technology

In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world.

Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover.

Introduction

Danielopol (1972) described from a marine cave in Cuba the first troglobitic ostracode in the suborder Halocypridina, a suborder previously known from the open ocean, where most members are planktonic. Since then, the number of known troglobitic anchialine species in that suborder has increased rapidly to 15, including the six new species from the Bahamas described herein. Three of the new species are in the genus Deeveya (Halocyprididae), which appears to be endemic to the Bahamas (including the Turks and Caicos Islands), and brings the number of its known species to six. The remaining three new species from the Bahamas are in the genus Spelaeoecia (Halocyprididae), a genus known previously only from Bermuda, and brings the number of known species to four. One of the five known troglobitic species of a more widely distributed genus in this suborder, Danielopolina (Thaumatocyprididae), is from the Bahamas (Eleuthera Island), but none were in the present collections. The world distribution of troglobitic anchialine ostracodes in the suborder Halocypridina is shown in Table 1. Also presented herein are brief supplementary descriptions of Deeveya spiralis, D. bransoni, and D. jillae based on a restudy of the type specimens. The locations of Bahamian islands having caves from which troglobitic Halocypridina have been collected are shown in Figure 1 (only those islands having troglobitic ostracodes are named in the figure).

ABBREVIATIONS.—In the figures, Arabic numerals indicate limbs 1–7, as well as individual joints of each limb (the location of the numeral indicating whether a limb or joint is indicated). Roman numerals I–III indicate the endites.

The following abbreviations are used in the figures: a.m. = adductor muscle; ant. = antenna; B.O. = Bellonci organ; bas = basale; c.o. = copulatory organ; cox = coxale; end = endopodite; epip = epipodite; esop = esophagous; ex = exopodite; g.p. = glandular process; gen = genitalia; i.m. = inner margin of infold; l.p. = lamellar prolongation of list of selvage; mnd = mandible; mx = maxilla; precox = precoxale; u.p. = unpaired process.

USNM catalog numbers apply to collections in the National Museum of Natural History (NMNH), Smithsonian Institution (SI).

METHODS.—Specimen and environmental data collection were made by Yager and Williams. All specimens were fixed in formalin and then changed to 70% ethyl alcohol, and were placed in glycerin prior to examination.

Specimens were measured with an ocular micrometer and are reported to the nearest 0.01 mm. Measurements are maximum length and height; each specimen was measured oriented with the straight hinge of the dorsal margin up, including or excluding processes as indicated. Drawings were made with a camera lucida; some appendages were drawn with the appendage mounted in glycerine and under a cover slip.

ACKNOWLEDGMENTS.—Jill Yager and Dennis Williams collected the samples; Jill Yager described the habitats; Louis S. Kornicker is the author of the new taxa. Field notes on El Dorado Cave were compiled by members of Project Andros 1986: Michael Madden, Parker Turner, Roger Werner, and Dennis Williams.

We thank the following people for their help: Jack R. Schroeder (SI) for inking camera lucida drawings of carapaces and appendages and the shell length-height graph; Martin V. Angel (National Institute of Oceanography, Wormley, Godalming, Surrey, England) and Thomas E. Bowman (SI) for reviewing the manuscript, Elizabeth Harrison-Nelson (SI) for general assistance, and Don Fisher (SI) for final editing and preparation of the manuscript for publication. Field studies were supported in part by the following (to Yager): Lerner-Gray Fund for Marine Research, American Museum of Natural History; Cave Research Foundation; National Speleological Society (NSS) Cave Diving Section; NSS Ralph W.

Habitats

ALFONSO DEAN BLUE HOLE (Hard Bargain Settlement, Long Island, Great Bahama Bank).—Although the entrance to this cave system is a small hole about 2 m in diameter, the cave widens into a classic bell-shaped room. The salinity increases with depth from about 9‰ at the surface, 20‰ at 13 m, and 30‰ at depths over 17 m. Tidal fluctuation is evident. The ostracodes were collected at a depth of about 13 m in the weakly photic or twilight zone of the cave. Dissolved oxygen content of water at that depth was recorded at less than 1 mg/l. The cave is inhabited by the ostracode Spelaeoecia capax, new species. Other animals in the cave include thermosbaenaceans, copepods, shrimp, and a free-swimming polychaete.

DAN'S CAVE (Abaco Island, Little Bahama Bank).—Located about 3 km from the sea, this cave is a typical Bahamian limestone cave with a distinct lens of fresh water overriding deeper saline water (Yager, 1987a:318). Tidal fluctuation is evident. The ostracodes were collected in the aphotic zone beneath the density interface in marine water of about 33‰. The oxygen content of this water is less than 1 mg/l. The cave fauna includes 2 new species of ostracodes, Deeveya styrax and D. hirpex, and a diverse group of crustaceans that appears to be common to anchialine environments: remipedes, thermosbaenaceans, cirolanid isopods, shrimp, and nebaliaceans. The only vertebrate observed in this cave is the Bahamian blind cave fish, Lucifuga speleotes Cohen.

EL DORADO CAVE (South Andros Island, Great Bahama Bank).—The cave is northwest of Congo Town and is one of a series of inland cave openings along an extensive north-south slumping fracture or fault. The openings are basically parallel to the eastern coast of the island and about 1 or 2 km inland. El Dorado Cave is located along the trail between Rat Bat Cave to the north and Swimming Hole (used by local children) to the south. El Dorado is a deep vertical fissure that extends to a depth of about 91 m. The water chemistry is typical of most anchialine caves in the Bahamas in which salinity increases with depth and dissolved oxygen decreases (Yager, 1987a:318). Tidal fluctuation is evident. The salinity was measured at 13‰ at the surface, 24‰ at 20 m, and 36‰ at 33 m. The dissolved oxygen was measured at 5.5 mg/l at the surface. A distinct layer of hydrogen sulfide was indicated when a white bacterial cloud was encountered at a depth of 10–20 m. At this depth the dissolved oxygen was less than 0.05 mg/l. At 30 m the dissolved oxygen was 0.1 mg/l. The ostracode Spelaeocia styx, new species, was collected in this cave. In addition to the ostracodes, the thermosbaenacean Tulumella bahamensis Yager, 1987b, as well as unidentified copepods were collected. Gliding bacteria of the Beggiatoa-Thiothrix group were observed in the water column at 30 m depth.

SAGITTARIUS CAVE (Sweeting's Cay, Grand Bahama Island, Little Bahama Bank).—This cave is one of the Zodiac Caverns, a complex system of submerged caves beneath Sweeting's Cay, a small island at the eastern end of Grand Bahama Island. The cave entrance is in a shallow saline lake behind the government dock and school. Tidal fluctuation is evident. Cunliffe (1985, table 1) listed the fauna and flora of the lake and cave including 2 ostracode genera, Deeveyne (= Deeveya) and Speleocia (= Spelaeoecia). Three new species, D. styrax, D. medix, and S. sagax, are referred to those genera herein. A detailed study of the physical characteristics of the cave is now in progress by two of us (Yager and Williams), and preliminary results indicate that the cave is marine with a salinity of 35‰, and although the lake is well oxygenated at 5 or 6 mg/l, the oxygen content of the cave water is variable and much lower, reaching less than 1 mg/l at a depth of 16 m. The troglobitic cave inhabitants include the Bahamian blind cave fish, 6 species of remipedes, 2 species of thermosbaenaceans, 2 species of amphipods, a stygiomysid, a cirolanid isopod, and unidentified copepods.

Suborder HALOCYPRIDINA Dana, 1853

COMPOSITION.—This suborder comprises the superfamilies Halocypridoidea Dana, 1853, and Thaumatocypridoidea Müller, 1906. Both superfamilies have been reported previously in anchialine caves in the Bahama Islands (including Turks and Caicos Islands) (Kornicker and Iliffe, 1985:476; Kornicker and Palmer, 1987:610; Kornicker and Iliffe, 1989a). Only the Halocypridoidea are represented in the collections reported upon herein.

DISTRIBUTION.—Species of Halocypridoidea that have been collected in caves, including those reported herein, are listed in Table 1. With the exception of Euconchoecia bifurcata pax Kornicker in Kornicker and Iliffe, 1989a, from Palau, which is probably troglophylic, species listed have been interpreted to be troglobitic. Troglobitic species of Thaumatocypridoidea are more widespread than those of Halocypridoidea, which are known only from the Bahamas and Bermuda (Table 1).

Superfamily HALOCYPRIDOIDEA Dana, 1853

COMPOSITION.—This superfamily contains only the family Halocyprididae Dana, 1853.

Family HALOCYPRIDIDAE Dana, 1853

COMPOSITION.—The family comprises the subfamilies Halocypridinae Dana, 1853, Conchoecinae Claus, 1891, Archiconchoecinae Poulsen, 1969, Euconchoecinae Poulsen, 1969, and Deeveyinae Kornicker and Iliffe, 1985. Only the Deeveyinae are represented in the collections reported upon herein.

Subfamily DEEVEYINAE Kornicker and Iliffe, 1985

COMPOSITION.—The subfamily comprises the genera Deeveya Kornicker and Iliffe, 1985, and Spelaeoecia Angel and Iliffe, 1987.

DISTRIBUTION.—Members of this subfamily have been reported from Bermuda and the Bahama Islands (including Turks and Caicos Islands) (Table 1).

TERMINOLOGY.—The lettering of bristles of the 1st and 2nd antennae is that used by Kornicker and Palmer (1987:610–611) for Deeveya, and Kornicker (1989:314) for Spelaeoecia, and is based on the lettering system used by Skogsberg (1920:188, 575) for other taxa. The terminology used for the 6th limb is that mentioned by Angel and Iliffe (1987:551) as “segmentation that should be reconsidered”: the exopodite is interpreted to have 3 joints, and the joint considered to be the 1st exopodial joint in prior terminology is interpreted to be the basale, and the process (bearing 4–5 bristles) previously considered to be part of the 1st exopodial joint is interpreted to be the endopodite.

DISCUSSION.—The carapaces of species of Spelaeoecia differ from those of Deeveya in having a well-defined rostrum. The males of Spelaeoecia differ from males of Deeveya in 2 important characters: (1) the endopodite of the 2nd antenna bears a clasper on Spelaeoecia that is absent on Deeveya; (2) the posterior branch of the copulatory organ of Spelaeoecia has a narrow hirsute tip but is broadly rounded on Deeveya. Additional differences in the genera are listed in Table 2.

Posterodorsal corner of right valve with gland-bearing protuberance (Figure 2d,e,g,i).

Ornamentation: Surface with few long single bristles; small bristle at tip of protuberance in posterdorsal corner of right valve (Figure 2e,g,i). Surface appearing smooth, but at high resolution (× 40 objective, × 15 ocular, transmitted light) indistinct oblique striations observed on parts of valves (Figure 2h) (striations probably more distinct on living specimens). Edge of valve with 1 or 2 (usually 1) minute bristles between each pair of glandular tubes (Figure 2j).

Infold (Figure 2g): Broad infold except along hinge, narrower just posterior to inner end of incisur (Figure 2g); narrow list at about midwidth of infold extending from just ventral to incisur to posteroventral corner of valve; a 2nd list forming sclerotized bar just posterior to posterior hinge juncture, then extending ventrally as narrow ridge intersecting valve edge at posteroventral corner (Figure 2g).

Glands: Posterodorsal corner of right valve with protuberance bearing along dorsal edge 5 or 6 minute glandular openings forming row just anterior to minute V-shaped indentation (detail in Figure 2g); small bristle at posterior corner of indentation. Left valve with minute glandular protuberance about halfway between posterior hinge juncture and posterodorsal corner of valve (Figure 2c). Outer edge of infold with minute tube-like glandular openings between point just ventral to incisur and posterior hinge juncture (USNM 193440 with about 18 tubes on each valve, mostly along anteroventral and ventral margins (Figure 2j), none observed along anterior edge of rostrum, and very few along posterior margin of valve).

Selvage (Figure 2g,j): Narrow bare lamellar prolongation extending from point just ventral to incisur to posterodorsal corner of each valve, not observed along either edge of rostrum or straight edge of valve between posterior hinge juncture and posterodorsal corner (on right valve prolongation not present dorsal to apex of glandular protuberance).

Hingement: Each valve with narrow sclerotized ridges forming bar between posterior juncture of hinge and posterodorsal corner of valve that may serve as locking structures when valves are closed (exact configuration of ridges difficult to resolve with light microscopes) (Figure 2g).

Central Adductor Muscle Attachments (Figure 2a,b,g): Difficult to determine exact number on specimens in collection, 3 of the scars on right valve of USNM 193440 shown in Figure 2g.

Carapace Size: USNM 193440, length 0.98 mm, height 0.55 mm; USNM 193441, length 0.98 mm, height 0.46 mm.

First Antenna (Figures 2b, 3a,b): With 8 joints but 3rd and 4th joints partly fused, boundary indicated by ventral and dorsal marginal indentations: 1st joint with terminal ventral lobe with numerous short spines; 2nd joint with short, indistinct, diaphanous, dorsal bristle, and distal medial spinules; 3rd joint bare, longer than 4th; 4th joint with short dorsal bristle with indistinct short marginal spines. 5th joint slightly shorter than 4th, with 1 or 2 long ventral unringed filaments. 6th joint shorter than 5th, bare. 7th joint about same length as combined 5th and 6th joints, with short spinous dorsal a-bristle, ventral b-bristle about images length of c-bristle, and long ventral c-bristle. 8th joint small with 4 terminal bristles (anterior medial d-bristle about twice length of a-bristle; long lateral e-bristle about same length as c-bristle, stout with indistinct rings and few widely spaced minute marginal spines; medial, f-bristle narrow, about images length of e-bristle and oriented obliquely ventrally; and long, stout, g-bristle lateral to f-bristle and ventral to e-bristle, about images length of e-bristle). The b- to g-bristles with terminal papillae. (The diaphanous bristle on the dorsal margin of the 2nd joint could be easily overlooked; it appears spine-like with the ×10 and ×20 objectives, but is bristle-like with the ×40 and ×100 objectives using ordinary transmitted light).

Seventh Limb (Figure 7n,p): Similar to that of adult male.

Furca (Figure 7o): Similar to that of adult male except “unpaired” bristle bifurcate (not 2 separate bristles as on adult male).

Genitalia: Small process bearing terminal spine present on left side of body between epipodite of 6th limb and proximal end of 7th limb in vicinity of receptaculum seminis, which was not visible (Figure 7p).

Gut Content: Gut gorged with many crustacean-like claws, but not otherwise identified. (The contents of the gut suggest that the species is either a carnivore or scavenger.)

Maturity and Sex of Specimen: Not known with certainty. Two oval masses containing globules, both inside the posterior part of the body, could be eggs. The furca of the specimen bears 7 claws on each lamella, the same number as on the adult male, which indicates the specimen is either the adult or A-1 stage. The absence of a copulatory limb, as well as the lack of a convex dorsal margin on the endopodite of the 2nd antenna, both present on the A-1 male S. bermudensis described by Kornicker and Iliffe (1989b), indicate that the specimen is not male. The carapace of the specimen is shorter than those of the 2 adult males in the collection (0.82 mm for specimen, 0.98 mm for 2 adult males). The specimen bears a small spined process on the left side of the body between the epipodial appendage of the 6th limb and the 7th limb (Figure 7p); a similar process was found on the adult female S. bermudensis described by Kornicker and Iliffe (1989b), as well as on the adult female of S. sagax, new species, described herein. Because of the spined process, it is tentatively concluded that the specimen is an adult female.

COMPARISONS.—The carapace of S. styx differs from that of S. bermudensis in being smaller and in having the gland in the posterodorsal corner of the right valve on a small projecting process. The 1st antenna differs in not having ventral bristles on the 3rd and 4th joints; also, the dorsal bristle on the 2nd joint of styx differs from that of bermudensis in being diaphanous and shorter. The furca of styx differs from that of bermudensis in not having claw 2 on a stout protuberance. Known specimens of bermudensis have claw 2 of the furca broken off near its base, whereas all 3 specimens of S. styx in the present collection have claw 2 unbroken. Additional differences are listed in Table 3.

VARIABILITY OF UNPAIRED BRISTLE OF FURCA.—The distibution of bifid and single unpaired bristles on 12 specimens of S. sagax is 4 single and 8 bifid.

COMPARISONS.—The 1st antenna of S. sagax differs from that of S. bermudensis in having a shorter dorsal bristle on the 2nd joint and no ventral bristles on the 3rd and 4th joints. The short dorsal bristle on the 2nd joint of the 1st antenna of S. sagax is well defined, not diaphanous as on S. styx. The basale of the mandible of S. sagax differs from that of S. styx in having 1 instead of 2 minute lateral bristles. The posterodorsal shell gland of S. sagax is not on a process projecting well above the dorsal shell edge as on S. styx. The carapace of S. sagax is much larger than that of S. styx (male S. sagax length 1.63–1.73 mm, male S. styx length 0.98 mm). The adult S. sagax bears 8 furcal claws compared to 7 on S. styx. The 2nd furcal claw is unbroken on both S. sagax and S. styx, but is broken on known specimens of S. bermudensis. The tip of the anterior lobe of the copulatory organ of the male S. sagax is without the numerous teeth on that of S. styx and without the large foot-like process on the organ of S. bermudensis (Kornicker, 1989). The unpaired bristle posterior to the furca of both S. bermudensis and S. styx is bifid, whereas S. sagax has either simple or bifid bristles, but the latter about twice as often.

DISCUSSION OF VENTRAL APRON.—Angel and Iiffe (1987:617) designated a curving shield anterior to both the anus and leading edge of the furca as the “apron.” Apparently when fecal pellets are extruded from the anus the apron is pushed away from the furca (Figure 13a,c). The apron protects the anus when a fecal pellet is not being extruded, and probably helps prevent feces from fouling appendages anterior to the apron. The apron is present on all known species of the genera Spelaeoecia and Deeveya.

Spelaeoecia capax Kornicker, new species

FIGURE 14

ETYMOLOGY.—From the Latin capax (spacious) in reference to large size of the species.

MATERIAL—Alfonso Dean Blue Hole, Long Island, Great Bahama Bank, 3 Aug 1985, USNM 193449, 1 carapace (holotype).

DISTRIBUTION.—Known only from Alfonso Dean Blue Hole.

REMARKS.—The senior author received 2 specimens of which the smaller was lost along with the body, but not the carapace, of the other. Additional specimens are not available, nor are additional collections planned by the junior authors. Therefore, the carapace of the specimen is described herein. Because the morphology of the carapace clearly shows it to belong to an undescribed species, and because the locality where it lives is confined, and so additional specimens should eventually be collected, the species is named rather than left in open nomenclature. Before the specimens were lost they were identified as a species of Spelaeoecia.

FIGURE 14.—Spelaeoecia capax Kornicker, new species, holotype, USNM 193449, sex unknown, length 2.49 mm: a, complete specimen from right side showing glands (not all marginal glands shown); b, inside view of right valve; c, inside view of posterior part of flattened valves; d, outside view of rostrum of right valve showing glands; e, inside view of anterior of left valve, outside surface of shell stippled; f, inside view of rostrum of left valve, outer surface of shell stippled; g, inside view of inside of posterior of right valve with small part of left valve attached; h, inside view of part of ventral margin of right valve showing marginal glands and ducts leading to pores; i, outside view of posterodorsal gland of right valve.

DESCRIPTION (Figure 14).—Carapace uncalcified, flexible, elongate; dorsal margin straight, ventral margin broadly convex; anterior incisur dorsal to midheight (Figure 14a,b). Anterior of valve viewed from inside with edge of valve slightly sinuate (Figure 14e,f); anterior outer part of rostrum broadly overreaching edge of valve and with rounded tip (Figure 14e,f); in lateral view posterodorsal corner of each valve evenly rounded (Figure 14a–c).

Ornamentation: Surface with fairly long bristles forming row just within valve edge, and minute bristles along valve edge. Surface with thin, slightly oblique striations.

Infold: Broad infold especially along shell posterior. Narrow posterior list forming narrow bar posterior to posterior juncture of hinge, then extending ventrally as narrow ridge intersecting valve edge at posteroventral corner (Figure 14b,c,g). (Anteroventral and ventral list present on previously described species of the genus not present, but that list tends to be less well developed or absent in juveniles, and possibly explains its absence in S. capax.)

Glands: Posteroventral corner of right valve with numerous minute glandular openings, many more than on previously described species of Spelaeocia, but exact number could not be determined because of their small size (Figure 14c,g,i). Distinct amber cell clusters in anterior part of shell and along margins, each cluster with duct leading to small external pore (Figure 14a,d,h) (ducts leading from marginal clusters to valve edge easily visible (Figure 14h), but more difficult to see away from valve edge).

Carapace Size: USNM 193449, length 2.49 mm, height 1.27 mm.

COMPARISONS.—The carapace of S. capax is much larger than those of known species (maximum length in mm: S. capax 2.49, S. bermudensis 1.64; S. styx 0.98; S. sagax 1.77). The posterior infold is much broader in S. capax than in other species. The large glandular clusters in the anterior part of each valve of S. capax are not present on previously described species. The gland at the posterodorsal corner of the right valve of S. capax has many more pores than in other species.

On each side of body, just lateral to, or just within unknown receptacle lies an elongate “horizontal organ” containing thin thread-like horizontal filaments (Figure 17j); the organ lies dorsal to the gut in lateral view and on each side of it in dorsal view. The functions of the unknown receptacle, as well as the vertical and horizontal organs are unknown.

FIGURE 21.—Deeveya styrax Kornicker, new species, paratype, USNM 193452, adult female, length 3.00 mm: a, right 1st antenna (only proximal part shown of bristles of distal joints) and Bellonci organ, lateral view; b, joints 5–8 of left 1st antenna, medial view; c, endopodite of left 2nd antenna, medial view; d, endopodite of right 2nd antenna (only proximal part shown of bristles of joints 2 and 3), medial view; e, distal parts of coxale and basale of right mandible, anterior to left (not under cover slip), medial view; f, right 7th limb, lateral view; g, right lamellar of furca, lateral view; h, posterior of body from left side (only proximal parts shown of furcal claws), anterior to left; i, posterior part of body from left side showing 7th limb and genitalia, anterior to left.

FIGURE 22.—Comparison at same magnification (×20 objective, × 15 ocular) of 3rd joints of the 1st antennae of species of Deeveya (all except D. jillae, which is from an A-1 male, are from adult males or females): a, D. spiralis, holotype, USNM 193117, adult female, left limb, medial view; b, D. jillae, holotype, USNM 193298, A-1 male, left limb, medial view; c, D. bransoni, holotype, USNM 193301, adult female, left limb, medial view; d, D. styrax, paratype, USNM 193452, adult female, right limb, lateral view; e, D. hirpex, holotype, USNM 193593, adult female, right limb, lateral view; f, D. medix, holotype, USNM 193592, adult male, left limb, medial view.

Deeveya spiralis Kornicker and Iliffe, 1985:476, figs. 1–13.—Kornicker and Palmer, 1987:619, fig. 6.

MATERIAL.—Holotype, USNM 193117, adult female; paratype, USNM 193118, adult female.

DISTRIBUTION.—The Hole, a marine cave on Providenciales Island, Caicos Islands, Turks and Caicos Islands.

REMARKS.—Kornicker and Iliffe (1985:477) interpreted the 2 specimens of D. spiralis in their collection to be adult females; because of having only 7 claws on each lamella of the furca they were interpreted to be A-1 females by Kornicker and Palmer (1987:621); reexamination of the holotype revealed a well-developed genital tube, which, combined with the large size of unextruded eggs in the ovaries, led to the conclusion herein that the 2 specimens are adult females, as originally described.

SUPPLEMENTARY DESCRIPTION OF ADULT FEMALE (Figure 22a, 23a–c, 29a, 30).—Mandible (Figure 23a): Coxale endite with bristle on anterior and posterior ends of proximal tooth.

Sixth Limb: End joint of 6th limb of holotype with 4 or 5 bristles (2 claw-like, 1 short, 1 or 2 long ventral).

Furca: Gland leading to pore between 1st and 2nd claws.

Genitalia (Figure 23b,c): Left side of holotype with genital tube. 3 bristles in vicinity of tube and posterior to base of 7th limb.

FIGURES 22c, 23d,e, 29b, 30

Deeveya bransoni Kornicker and Palmer, 1987:610, figs. 1–6.

MATERIAL.—Holotype, USNM 193301, adult female; paratype, USNM 193302, A-1 female.

DISTRIBUTION.—Evelyn Green's Blue Hole and Stargate Blue Hole, South Andros Island, Great Bahama Bank.

REMARKS.—Kornicker and Palmer (1987:611) interpreted the 2 specimens in their collection to be A-1 female (holotype) and A-2 female (paratype). Reexamination of the A-1 female revealed a well-developed genital tube and 2 bristles in its vicinity; this led to the conclusion herein that the holotype is an adult female. The paratype is without genitalia and is interpreted to be an A-1 female.

SUPPLEMENTARY DESCRIPTION OF ADULT FEMALE (Figure 22c, 23d,e, 19b, 30).—Mandible (Figure 23d): Coxale endite with bristle on anterior and posterior ends of proximal tooth. Basale with 4 proximal bristles (1 long slender bristle with short marginal spines and 3 plumose bristles (2 long, 1 short)) (Kornicker and Palmer (1987:615, fig. 2a) overlooked the short plumose bristle).

Furca: Kornicker and Palmer (1987:617) incorrectly stated that a stout triangular protuberance follows claw 7; no protuberance is present, and its absence is correctly indicated in their illustration of the furca (Kornicker and Palmer, 1987, fig. 3d). (A triangular protuberance is present following the 6th furcal claw of the A-1 female, and it probably is an Anlage of the 7th claw of the adult.)

Genitalia (Figure 23e): Left side of holotype with genital tube. 2 bristles in vicinity of tube.

Endopodite with 1 proximal medial bristle and 7 ventral bristles (2 claw-like unringed pectinate). 1st exopodial joint divided into 2 parts: proximal part with 7 bristles (1 very long bare terminal dorsal bristle, 1 shorter plumose dorsal bristle just proximal to terminal bristle, 1 distal plumose lateral bristle at midwidth, 1 subventral lateral bristle, 1 subventral medial bristle with short marginal spines, and 2 ventral bristles); distal part with 3 bristles on or near ventral margin. 2nd exopodial joint with 1 dorsal and 2 ventral bristles. 3rd exopodial joint with 4 terminal bristles. Limb illustrated in Kornicker and Iliffe (1989a, fig. 13a).

Copulatory Organ (Figure 23g): With 2 branches: anterior branch more weakly developed and narrower than posterior branch, with transparent triangular process at tip; posterior branch with minute rounded process at tip. (It is possible that anterior and posterior branches are twisted on specimen and could be reversed.)

COMPARISONS.—The carapace of D. hirpex is smaller than those of D. styrax and D. spiralis, and larger than that of D. bransoni (Figure 30). The adult of D. jillae is unknown but the small size of the A-1 instar suggests that adults will be much smaller than D. hirpex (Figure 30). The clear round disks at intersections of reticulations of D. hirpex are larger than those of D. styrax, D. spiralis, and D. bransoni, but slightly smaller than those of D. jillae (Figure 29). The 3rd joint of the 1st antenna of D. hirpex (Figure 22e) is more elongate than that of D. jillae (Figure 22b).

COMPARISONS.—Carapace of D. medix similar to that of D. jillae in having large disks. Adult D. jillae unknown, but length probably with range of 1.32–1.35 mm (determined by multiplying length of A-l male (1.07 mm) by estimated growth factors of 1.23 and 1.26), much shorter than length of adult male D. medix (1.73 mm) (Figure 30). 3rd joint of 1st antenna of D. medix more elongate than that of D. jillae (width of distal end of 3rd joint of 1st antenna as percent of length of dorsal margin 31% for D. medix (Figure 22f) and 38% for D. jillae (Figure 22b)). Carapace of adult D. hirpex much larger than that of D. medix (length 2.36 mm compared to 1.73 mm)(Figure 30). Carapace of D. medix differing from that of D. bransoni in having larger disks at intersections of walls of reticulations (Figure 29b,f).

DISCUSSION OF GENUS

The carapaces of known species of Deeveya mainly differ in overall size (Figure 30) and in the diameter (relative to breadth of polygons) of disks at the intersections of walls forming polygons (Figure 29). The carapace of D. spiralis differs from those of other species in having bifurcating rather than simple bristles along the anterior margin. The 1st antennae of some species differ in length (relative to width) of the 3rd joint (Figure 22). The spination of the posterior bristle of the end joint of the endopodite of the mandible differs on some species (D. spiralis and D. bransoni). The end joint of the exopodite of the 5th limb of D. spiralis bears 5 bristles, whereas other species have only 4. The number of bristles in the 3 groups of bristles farming the epipodites of the 5th and 6th limbs may differ slightly among species but intraspecific variability is not known, and these bristles are difficult to count on an undissected specimen and easily break off during dissection. The 5th and 6th furcal claws of D. spiralis bear stouter marginal teeth than those claws of other species. The number of bristles on appendages of known species are compared in Table 2, but intraspecific variability is not known. The adult male is known only for D. styrax and D. medix, but the considerable differences in the tip of the anterior branch of the copulatory organ of those species indicates that it will be useful in identifying other species.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

Manuscripts intended for series publication receive substantive review (conducted by their originating Smithsonian museums or offices) and are submitted to the Smithsonian Institution Press with Form SI-36, which must show the approval of the appropriate authority designated by the sponsoring organizational unit. Requests for special treatment—use of color, foldouts, case-bound covers, etc.—require, on the same form, the added approval of the sponsoring authority.

Review of manuscripts and art by the Press for requirements of series format and style, completeness and clarity of copy, and arrangement of all material, as outlined below, will govern, within the judgment of the Press, acceptance or rejection of manuscripts and art.

Copy must be prepared on typewriter or word processor, double-spaced, on one side of standard white bond paper (not erasable), with 1art″ margins, submitted as ribbon copy (not carbon or xerox), in loose sheets (not stapled or bound), and accompanied by original art. Minimum acceptable length is 30 pages

Front matter (preceding the text) should include: title page with only title and author and no other information, abstract page with author, title, series, etc., following the established format; table of contents with indents reflecting the hierarchy of heads in the paper; also, foreword and/or preface, if appropriate.

First page of text should carry the title and author at the top of the page;second page should have only the author's name and professional mailing address, to be used as an unnumbered footnote on the first page of printed text.

Center heads of whatever level should be typed with initial caps of major words, with extra space above and below the head, but no other preparation (such as all caps or underline, except for the underline necessary for generic and specific epithets). Run-in paragraph heads should use period/dashes or colons as necessary.

Tabulations within text (lists of data, often in parallel columns) can be typed on the text page where they occur, but they should not contain rules or numbered, table captions.

Formal tables (numbered, with captions, boxheads, stubs, rules) should be submitted as carefully typed, double-spaced copy separate from the text; they will be typeset unless otherwise requested. If camera-copy use is anticipated, do not draw rules on manuscript copy.

Taxonomic keys in natural history papers should use the aligned-couplet form for zoology and may use the multi-level indent form for botany. If cross referencing is required between key and text, do not include page references within the key, but number the keyed-out taxa, using the same numbers with their corresponding heads in the text.

Synonymy in zoology must use the short form (taxon, author, year:page), with full reference at the end of the paper under “Literature Cited.” For botany, the long form (taxon, author, abbreviated journal or book title, volume, page, year, with no reference in “Literature Cited”) is optional.

Text-reference system (author, year:page used within the text, with full citation in “Literature Cited” at the end of the text) must be used in place of bibliographic footnotes in all Contributions Series and is strongly recommended in the Studies Series:“(Jones. 1910:122)” or “…Jones (1910:122).” If bibliographic footnotes are required, use the short form (author, brief title, page) with the full citation in the bibliography.

Footnotes, when few in number, whether annotative or bibliographic, should be typed on separate sheets and inserted immediately after the text pages on which the references occur. Extensive notes must be gathered together and placed at the end of the text in a notes section.

Bibliography, depending upon use, is termed “Literature Cited,” “References,” or “Bibliography.” Spell out titles of books, articles; journals, and monographic series. For book and article titles use sentence-style capitalization according to the rules of the language employed (exception: capitalize all major words in English). For journal and series titles, capitalize the initial word and all subsequent words except articles, conjunctions, and prepositions. Transliterate languages that use a non-Roman alphabet according to the Library of Congress system. Underline (for italics) titles of journals and series and titles of books that are not part of a series. Use the parentheses/colon system for volume (number): pagination: “10(2):5–9.” For alignment and arrangement of elements, follow the format of recent publications in the series for which the manuscript is intended. Guidelines for preparing bibliography may be secured from Series Section, SI Press

Legends for illustrations must be submitted at the end of the manuscript, with as many legends typed, double-spaced, to a page as convenient.

Illustrations must be submitted as original art (not copies) accompanying, but separate from, the manuscript. Guidelines for preparing art may be secured from Series Section. SI Press. All types of illustrations (photographs, line drawings, maps, etc.) may be intermixed throughout the printed text. They should be termed.

Figures and should be numbered consecutively as they will appear in the monograph. If several illustrations are treated as components of a single composite figure, they should be designated by lowercase italic letters on the illustration; also, in the legend and in text references the italic letters (underlined in copy) should be used: “Figure 9b.” Illustrations that are intended to follow the printed text may be termed Plates, and any components should be similarly lettered and referenced: “Plate 9b.” Keys to any symbols within an illustration should appear on the art rather than in the legend.

Some points of style: Do not use periods after such abbreviations as “mm, ft, USNM, NNE.” Spell out numbers “one” through “nine” in expository text, but use digits in all other cases if possible. Use of the metric system of measurement is preferable; where use of the English system is unavoidable, supply metric equivalents in parentheses. Use the decimal system for precise measurements and relationships, common fractions for approximations. Use day/month/year sequence for dates: “9 April 1976.” For months in tabular listings or data sections, use three-letter abbreviations with no periods: “Jan, Mar, Jun,” etc. Omit space between initials of a personal name: “J.B. Jones.”

Arrange and paginate sequentially every sheet of manuscript in the following order: (1) title page. (2) abstract, (3) contents, (4) foreword and/or preface, (5) text, (6) appendixes, (7) notes section, (8) glossary, (9) bibliography, (10) legends, (11) tables. Index copy may be submitted at page proof stage, but plans for an index should be indicated when manuscript is submitted.
