S. National Museum for study^ This series contamed material fi-om many sources, of which the most important werethe collections of the late Henry and Arthur Adams, of Pastel ofDunker, and Hilgendorf. Numerous specimens of species inade-quately described by Arthur Adams from Japan were among the mostvaluable tor our work, and the importance of accurately figuring and
:
adequately dcsc.ribing them was evident, as, until such descriptionswere made pubhc, no small number of species of the Japanese faunamust remain doubtful.Though mostly small and to many students uninteresting, the Pyra-midellida^^ exist in much larger numbers than is generally realizedlo obtain a satisfactory view of their specific characters, in mostcases the species must be studied under the microscope, and to getaccurate figures of these minute creatures enlarged photographs orcamera lucida drawings are essential. The difficultv of obtainino- thesein the present instance was much enhanced bv the death of ou" chiefdraftsman and faithful collaborator, the latc^ Dr. J. C. McConnell, forProceedings U. S.

Thenucleus was described from one specimen and the post-nuclear charac-ters from the most perfect individual in the collection^ which belongsto the same lot; this has sixteen post-nuclear whorls, and measures:long. 17, mm.; diam. 4.5 mm. This specimen is a little more slenderthan the average individual. One, having fourteen post-nuclear whorls,measures: long. 14.2 nun.; diam. -4.3 mm. Some show five well-devel-oped, subequal and subequally spaced interrupted lirations on theouter lip. The line spiral striations are quite superficial and do notappear on specimens which are somewhat worn. There are two otherspecimens, No, 180076, in the U. S.

riate XXVI, %. 4.Ododomia panamensis Clessin, Mart. C'liein. Conch. Cab., 2(1 ed., Pyramid. 1900,p. 120; })1. XXVIII, fig. 9.Shell small, heavy, elongate-ovate, whorls increasing regularly insize, milk white, shining. Nuclear whorls small, almost completel}-obliquel}' immersed in the tirst of the succeeding volutions. Post-nuclear whorls moderately and evenly rounded, of porcellanous tex-ture, withoutany apparent marking, separated by well marked sutures.Periphery of the last whorl full and rounded. Base inflated, wellrounded. Aperture small, decidedly rissoid, almost channeled ante-riorlv, posterior angle acute; outer lip decidedlv curved backwardanteriorly, very thick within but beveled to form a sharp edge; colu-mella extremely short, somewhat reflected and connected posteriorlywith the very strong parietal callus, which is fully as thick as theedge of the outer lip and connects with it at the posterior angle ofthe aperture, thus forming a complete peristome. A prominentoblique fold is present on and a little anterior to the insertion of thecolumella.There are two specimens of this species in the Berlin collection fromPanama. We have considered the best preserved individuals, whichevidently served Clessin for his description and tig-ure as his type, andhave here rediagnosed and figured it. It has six post-nuclear whorlsand measures: Long., 3.1 mm.; diam., 1.5 mm.Clessin for some unaccounta])le reason changed the characters of theaperture in the above-cited figure to harmonize with the t3q:)icalOdosfoiiud. aperture. He seems to have failed entirely in recognizingthe peculiarities of the present species.??Ann, Mag. Nat. Hist., VIII, 1861, p. 304. &Ann. Mag. Nat. Hist, 1860.cCat. I, 1817, p. 508.
