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 1151, in 89 to 234 fathoms. An. 

 unusually large living specimen was taken by the Albatross at 

 station 2004, K 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 sutui-e 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
