marked, somewhat impressed suture. Whorls four, increasing rap- 

 idly, rising abruptly from the suture to the strongly convex shoulder, 

 and somewhat flattened at the periphery. The apical whorl is not 

 very small, but rather prominent. The body-whorl forms much the 

 larger part of the shell, and is rather evenly rounded in the middle, 

 strongly produced anteriorly, and narrowed gradually to the tip 

 of the short canal. The sculpture consists of very thin, raised, 

 rather close and regularly spaced revolving cinguli, of which there 

 are about twelve on the penultimate whorl ; on one specimen one of 

 these is a little more prominent than the rest. Fine, close, regular, 

 and distinctly raised flexuous lines of growth also cover the whole 

 surface of the lower whorls, crossing both the cinguli and their inter- 

 stices, but most distinctly the latter; these lines of growth are much 

 finer and more numerous than the cinguli ; the two upper whorls are 

 smooth. Aperture somewhat crescent-shaped, not very broad, 

 pretty evenly rounded on the outside, prolonged anteriorly into a 

 short rudimentary canal, and with the inner margin rather flexuous, 

 the columella-margin being straight or a little convex in the middle, 

 while there is a marked excurvature in the umbilical region; the lip 

 is thin, simple, but striated within by revolving lines which show 

 through. The canal is not difierentiated from the aperture by any 

 constriction, and ends in a simple and slightly prominent notch ; the 

 columella-lip is reflexed over the umbilicus, nearly concealing it in a 

 front view. The umbilicus seen in an end view is narrow and deep.

Station 2084, N. lat. 40° 16' 50", W. long. 67° 05' 15", in 1290 

 fathoms. Two living specimens (No. 38,077). 



The original specimens described by Friele were from 223 and 656 

 fathoms, and from 650 fathoms, ofFTromso. 



This shell agrees closely with the description and figure quoted. 

 It seems to me very doubtful whether it really belongs to the genus 

 Trichotropis. It may prove to belong to Admete.

Shell brown, small, rather thick, short and stout, composed of 

 about three rapidly increasing whorls, which are crossed by strong 

 transverse ribs, but are destitute of spiral lines. The apical whorl is 

 relatively rather large, regularly rounded, making a small, obtuse
