are two additional ones, nearly as strong, around the periphery, 

 and one or two faint ones on the subsutural band. On tlie last 

 whorl there are eight or nine revolving carinre below the shoulder, 

 besides six or seven on the siphon. The longitudinal sculpture con- 

 sists of numerous, rather narrow, angular, longitudinal ribs, which 

 run nearly straight across the whorls, parallel with the lines of 

 growth, which are rather conspicuous, distinctly raised and lamelli- 

 form, covering both the ribs and their interspaces. The ribs in 

 crossing the revolving carinse form small, rounded or subconical 

 nodules, of which those on the shoulder and on the sutural carina are 

 the most prominent and most compressed. The ribs are continued 

 across the subsutural band, on the lower whorls, in the form of thin, 

 raised lamellie, somewhat larger than the intervening lines of growth ; 

 but on the upper whorls the ribs, across the entire breadth, are thin, 

 lamelliform, and bent forward, rising in the form of small angles in 

 crossing the revolving cinguli. The surface is covered by a closely 

 adherent epidermis, which bears minute, sp:>rsely scattered hairs, 

 especially along the summits of the revolving cinguli. The nucleus 

 is minute, regularly coiled, depressed, and largely covered by the 

 succeeding whorl. The first or apical whorl is smooth and translu- 

 cent, but on the second the normal sculpture is gradually developed. 

 The aperture is rather broad-ovate, more than half the length of the 

 shell. Columella is straight, with a strongly sinuous inner margin. 

 The canal is rather short and broad, not constricted. The opei'culum 

 is thin, yellowish white, translucent, ovate, somewhat pointed poste- 

 riorly, and slightly truncated on the postei-ior part of the outer 

 margin ; the nucleus is at the extreme posterior tip. Color of the 

 shell white, with a pale flesh-colored tint on the spire.

Station 203S, N. lat. 38° 30' 30", W. long. 69° 08' 25", in 2033 

 fathoms, one living specimen (No. 34,840). 



The generic relations of this shell are somewhat doubtful. Tn 

 general appearance and sculpture it resembles certain species of Bela, 

 but the character of the nucleus and the hairy epidermis, together 

 with the character of the operculum, indicate that it belongs to or 

 near iSlpho. This is also indicated by the fact that there is no 

 distinct sinus in the outer lip, nor are the lines of growth distinctly 

 excurved in crossing the snbsutural band. In size and shape the shell 

 resembles J3ela hebes and Gymnohela curta^ var. angidata, from both 

 of which it differs decidedly in sculpture. The specimen described 

 may, however, be the young of a much larger species.
