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 differentiated 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, off Tromso. 
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.

Puate XXXII, FIGURE 9. 
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
