ing ribs, which are crossed by thin, raised, conceutric lines of growth, 

 so as to form a row of small granules or vaulted scales along each 

 rib. Along the sides the ribs are fainter, and posteriorly they are 

 nearly obsolete, while the concentric lines remain distinct. Color 

 grayish white. 



Length of aperture, 6'°'" ; breadth, 4-3""" ; height, 3""" ; length of 

 anterior slope, 6""". 



Station 1096, in 317 fathoms, N. lat. 39° 53', W. long. 69° 47', 

 1882 ; one specimen (No. 38,081). 



This species resembles C. Beanii in form, but has very different 

 sculpture. 



Cocculina conica Vernii. sp. nov. 



Shell very small, thin, translucent, white, rather high, conical, with 

 a very bi'oad-ovate or nearly round base and a prominent, sub-spirally 

 twisted apex, which is turned strongly backward, and obliquely to 

 the left. The sub-spiral apex is relatively rather large, and the 

 extreme tip seems to have been deciduous. The anterior slope of the 

 shell rises at first rather abruptly, and then becomes very convex, 

 forming the central and highest part of the shell, from which it 

 descends a little to the apex ; the posterior slope is concave under 

 the overhanging apex, and then descends with a short, abrupt slope 

 to the margin, which extends back but little beyond the apex. The 

 sculpture consists only of rather irregular, concentric raised lines of 

 growth, which run sub-spirally on the upper poi'tion of the shell. 



The animal, in alcohol, has a nearly round foot and two small, 

 slender, cylindrical tentacles, and is apparently without eyes. 



Length and breadth, about 1"'" ; height, about the same. 



Station 2078, in 499 fathoms, N. lat. 41° 12' 50", W. long. 66° 12' 2()". 



Puncturella (Fissurisepta) eritmeta Veniii, sp. nov. 



Plate XXXII, figures 19. 19a. 

 Shell small, thin, delicate, translucent white, glossy, moderately 

 elevated, with the base between elliptical and ovate, somewhat nar- 

 rowed anteriorly, having both ends evenly rounded and the sides 

 somewhat compressed, but still moderately convex. The apex is 

 minute, nearly central, compressed, turned backward, but scarcely 

 incurved, and with tlie extreme tip smooth and glossy. The pore is 

 very small, situated very close to the apex, and it a|>pears to be 

 divided by a slight transverse septum, across the niiddlo. The
