By A. L. Treadwell,Of the Department of Zoology, Vassar College, Poughkeepsle, New York.
INTRODUCTION.Some time ago the polychaetous annelid collections made by theUnited States Bureau of Fisheries- Steamer Albatross in the Philip-pines were sent me for description. As a result of a preliminarystudy the old species were identified and sent to the United StatesNational Museum some two years ago. Two new species were alsodescribed, but since pressure of other duties prevented my continuingthe work.the remainder of the collection was turned over to my as-sistant, Miss Ruth Hoagland, whose report follows this. A fewold species which I had overlooked are included in her report. Thesetwo papers together, then, comprise the report on the polychaetousannelids of this expedition.DESCRIPTION OF SPECIES.Family SYLLIDAE.Genus AUTOLYTUS Grube.AUTOLYTUS TRIANGULIFER Grube.Autolytus triangulifer Grube, 1S78, p. 132, pi. 7, fig. 8.The polybostricous stage was collected in considerable numbers atSan Miguel Harbor, Ticao Island. Grube reported that his speci-mens were incomplete. One specimen in this collection had in theposterior region 31 somites similar in structure, though narrowingvery noticeably toward the posterior end. These somites are largelycovered by the prominent parapodia. Somites 32, 33, 31, 19, 50,and 51 of the entire body have small parapodia and are covered dor-sally with a brownish pigment, an expansion of the median pigmentspots occurring in the anterior somites. Behind somite 11 was acolorless region containing about six somites with very small para-580

POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 5914lenger specimens. No elytra remained and the head in each wasbadly preserved, so that it was impossible to be certain as to theirnormal form. In all cases the head had been rolled over so that thebasal joint of the median antenna had been directly posteriorly.Some of the few remaining cirri showed a violet color and the innersurface of the proboscis is a dark color, as described by Mcintosh.Collected from D5122, Malabrigo Light, East coast of Mindoro,N. 46?

The specimen agreed with hisdescription except that he saw no antennae. No median antennawas preserved, but there were two lateral antennae with rather long,dark-colored basal portions nearly twice as long as the head, eachhaving a filamentous tip longer than the basal portion. On eachelytrophore, underneath the elytron, is a thin translucent plate likea shadow of the elytron.Mcintosh stated that the ventral setae are more prominent thanthe dorsal ones. In this specimen the dense tuft of slender serrateddorsal setae entirely obscures the stouter ventral one.

POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 593Family PHYLLODOCIDAE.Genus PHYLLODOCE Savigny.PHYLLODOCE DUPLEX Mcintosh.Pliyllodoce duplex McIntosh, 1885, p. 1G7, pi. 27, fig. 8; pi. 32, fig. 9; pi.15o, fig. 1.Collected at station D5113, Sombrero Island, Balayan Bay, 159fathoms, dark green mud bottom.Genus MYSTA Malmgren.MYSTA MACULATA, new species.A single specimen, with a length ?of approximately 60 mm. Widthof head between tentacles, 0.5 mm. ; width at somite 20, 1.5 mm.There were about 146 somitespresent, the posterior end havingbeen lost. Anteriorly the propor-tion of length of somite to breadthis as 1 to 8, and the dorsal cirri areinconspicuous. Beginning withapproximately the fortieth somitethere is a gradual change in theproportion of length to breadth,and toward the posterior end thisproportion is about as 1 to 2. An-teriorly the dorsal cirri are veryinconspicuous, and while theyoverlap one another to a certainextent they cover no part of thesomite surface. Posteriorly thesecirri become much more promi-nent, but still do not overlap thebody. Each dorsal cirrus ismarked with a median dark spot,rather faint anteriorly but veryprominent posteriorly. The gen-eral body color (in alcohol) is avery light brown, marked on thedorsal surface with dark spots,which in the anterior somites showa tendency to arrange themselves in a transverse row near theanterior border of the somite. Ventrally the body has a broadmedian dark band, spotted with white.The prostomium (fig. 1) is, roughly speaking, lens-shaped, withthe long diameter transverse, this long diameter being about one-fourth longer than the antero-posterior one. About one-quarter of

These are shorter than the head, ratherthick, and taper rapidly to a sharp point. Two other tentacles areattached to the ventral surface of the head and are not visible fromabove. These are similar to the dorsal tentacles in form, but areheavier. One pair of small eyes lies near the anterior border. Justposterior to the right hand one of these is a dark spot which re-sembles an eye, but is, I think, merely a surface marking. Twotentacular cirri on either side are attached to the first somite. Theyare much like the tentacles in form, but about twice as large. Themouth is bounded anteriorly by the prostomium, while about one-third of the posterior border is made up of an anterior prolongationfrom somite 2.The first parapodium is about two-thirds as long as the second, butis similar to it in all other respects.A well-developed parapodium (fig. 2?an anterior view of thefifteenth) shows the setigerous portion prolonged into bifid presetallip, behind which arises a row of about 25 compound setae withelongated basal joints. The notocirrus is broadly rounded and car-ried on a large cirrophore. The neurocirrus is bluntly conical inoutline, with its dorsal surface next the setigerous lobe rather deeplyexcavated.The compound seta (fig. 3) has the basal portion very slightlycurved, the convex side apparently with a narrow transparent edge,which thickens abruptly at the apex. The apex has a sharp hookat the end of the convex surface, with a much heavier curved hookopposite it. This larger hook lies a little inside the line of the con-cave margin, which is continued into a much smaller spine. Ap-parently other smaller spines of uncertain arrangement are locatedaround the base of the large hook. The terminal portion is broadat the base and tapers to a sharp point, the whole terminal portionbeing about as long as the free part of the basal portion. Near itsbase there are minute denticulations along its thinner edge. I was
'. . . ?unable to determine the extent of these denticulations, but thinkthat they do not go beyond the middle of the joint. With carefulfocussing, fine lines, giving it a shagreen appearance, may be seen onthe surface of this terminal joint.A later parapodium (fig. 4) shows a cirrophore larger than thecirrus, and there is a black spot in the center of the cirrus. In thepreparation the whole cirrus was bent away from the observer sothat the cirrus was really larger than appears in the figure. Thesetae in these parapodia are similar to those farther forward.Collected a? station D5146, Sulade Island, vicinity of Siasi, 24fathoms, coral sand and shell bottom.Type.?Cat. No. 18940. U.S.N.M.
POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 595Family NEREIDAE.The collection contained large numbers of heteronereis stages ofNereis. , Since during this phase the bodily changes are such as toobscure specific characters I have relied almost entirely in determin-ing species on the characters of the jaws and paragnaths. Thesedeterminations must therefore be regarded as provisional.Genus NEREIS Linnaeus.NEREIS MASOLOCENSIS Grube.Nereis masolocensis Geube, 187S, p. 75, pi. 5, fig. 4.The Albatross specimens corresponded exactly with these in re-spect to tooth structure. Grube states that 22 anterior somites aremarked with a brown stripe on either side. In these not more than17 or 18 were so marked. A prominent feature is a brown bandacross the entire dorsal surface of the second setigerous somite.Collected at Bohuao; Varadero Harbor, Mindoro; Subic; TavaIsland ; San Miguel Harbor ; Varadero Bay, Mindoro ; " Electriclight, July 20, 1908," station D5403, Capitancillo Island, betweenLeyte and Cebu, 182 fathoms, green mud bottom.NEREIS PECTINIFERA Grube.Nereis pectinifera Grube, 1S78, p. 66, pi. 4, fig. 5 ; pi. 5, fig. 5.Collected at Labuan Blanda Island.NEREIS TONGATABUENSIS Mcintosh.Nereis iongatabuensis McIntosh, 1885, p. 212, pi. 34, figs. 7, 8, 9 ; pi. 16a,figs. 5. 6, 7.Collected at Nasugbu Luzon.NEREIS (PLATYNEREIS) INTEGER, new species.An epitokous form, characterized by an enormous development ofthe prostomium, so that the antennae are thrown to the ventral sur-face, all that is visible from above being the enormous eyes and theshovel-shaped prostomium (figs. 1 and 2).Male.?The prostomium rounded, its margin entire, the portionanterior to the eyes being very thin and translucent. In some indi-viduals the palps may be seen through this translucent region. Theanterior eyes are the larger, and they are situated on the latero-ventral portion of the head.The dorsal tentacular cirrus (lost in the specimen figured) ex-tended in other specimens to the eighth somite. The median cirri-(fig. 1) are much shorter.On the ventral surface (fig. 2) appear the flattened antennae,which normally hang at right angles to the prostomium, but are

The large anterioreyes with their latero-ventrally directed lenses occupy a considerablepart of the ventral surface. Posterior and ventral to these are thepalps with their two portions nearly equal in size, hanging downso as to cover the sides of the mouth. While in the figure they areshown under slight pressure, their direction is only very slightlychanged by it.The jaws have each a large terminal and five smaller lateral teeth.I could discover no trace of paragraths.The dorsal cirri of the first seven somites are enlarged, increasingsuccessively in size until the seventh is reached (fig. 3 of theseventh ) . The notopodiumhas two obtuse subequallobes, the acicula-extendinginto a short conical lobebetween them. The neuro-podium has a dorsal coni-cal lobe, into which theacicula extends, and anobtuse ventral lobe similarto that of the notopodium.Dorsal cirrus elongated,its terminal portion bentand slightly flattened asshown, somewhat fore-shortened, in the figure.Setae of notopodiumwith long " camerated

shafts, the terminal jointset into rather a deepsocket. The terminal jointis long, slender, and verysharp pointed, with nu-merous very sharp teethalong the greater part ofone edge. The teeth areall drawn out into fine processes, which bend apically so that eachcovers over several of those distal to it. In the ventral bundle are afew similar to the dorsal and others having the terminal portionshort, narrow as compared with the basal joint, with one large toothat the apex and a row of very fine teeth along one margin.The parapodia, from eighth to fourteenth inclusive, are unmodified,though the general structure of neuropodium, notopodium, ventralcirri, and setae are essentially as in the seventh. The dorsal cirrusis much shorter and tapers slowly to a blunt end.

POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 597The parapodial modifications begin on somite 15. In a modifiedparapodium the neuropodium has a dorsal, and the notopodium aventral sagittal lobe, which overlap, the notopodial being anterior.Dorsal to the slender dorsal cirrus is a broad rounded lobe withventral to it, a lanceolate one extending to nearly the end of thecirrus. The ventral cirrus is much like the dorsal in form, but rela-tively a little heavier. Ventrally it carries a plate shaped like thatof the dorsal but larger. Dorsally, attached to its base, this cirruscarries a zigzag three-pronged outgrowth, while on the ventral sur-face of the neuropodium is another outgrowth very similar to thisbut with four prongs. The setae are of the usual type with broadterminal joint toothed along one edge.Most individuals show traces of brown spots on the dorsal sur-face. When best developed these appear in the anterior unmodifiedportion as prominent spots on the parapodia from the eighth to thefifteenth. In the modified portion there is a median dorsal and twolateral brown spots in each somite, with a double row of smallerbrown spots on the dorsal surface of each parapodium. Ventrallythese markings are most prominent in the modified region, wherethe median row breaks up into a double row of smaller spots and theparapodial row tend to coalesce into a single one.In the collections were a number of females in the epitokous condi-tion, but none which resembled the above-described males sufficientlyto justify one in identifying them as of this species.Collected from Subic Bay ; Santa Cruz Harbor, Marinduque ; SanMiguel arbor, Ticao Island, a large number of individuals beingfrom the latter locality ; Port Matalvi, Luzon, and Eomblon.Type.?Cat.
