This species was taken in 1882 at station 1092, in 202 fathoms, one 
young dead ; station 1097, in 158 fathoms, two young dead, with large 
fragments; station 1109, in 89 fathoms, one young dead; station 
1113, in 192 fathoms, one living; and fragments were also taken at 
stations 1117, 1120, 1121, and 1154, in 89 to 234 fathoms. An 
unusually large living specimen was taken by the Albatross at 
station 2004, N. lat. 37° 19’ 45”, W. long. 74° 26’, in 98 fathoms, 
March 23d, 1883 (No. 35,655). 
Mr. Dall thinks this species is identical with one from the Medi- 
terranean.

Shell small, conical, with a regularly tapering, acute spire, with a 
smooth, somewhat glossy surface, usually light chestnut-brown in 
color. Whorls about six in the largest specimens, moderately 
convex, with the suture well impressed, but not deep, usually show- 
ing by translucency an internal sutural line just below the suture. 
There is no distinct sculpture unless microscopic and very indistinct 
lines of growth. Apical whorl very minute, regularly spirally coiled, 
slightly prominent, so as to produce a very acute apex. Last whorl 
very large, somewhat swollen, forming more than half the length of 
the shell. Base moderately produced, without any umbilicus, and 
destitute of sculpture. Aperture short-ovate, with an acute angle 
posteriorly, broadly rounded in front, with the inner margin oblique 
and only slightly sinuous; the outer lip is thin and sharp, convex 
and evenly rounded; the columella-margin is excurved, with the 
edge thickened and slightly everted, closely covering the umbilical 
region ; it joins the anterior margin in a regular curve and continues 
along the margin of the body-whorl in a slightly sinuous line, form- 
ing there a distinct but closely adherent inner lip, consisting of a 
thin deposit continuous with the deposit of the umbilical region. 
Operculum subspiral, translucent, chestnut-brown. The shell is
