ing ribs, which are crossed by thin, raised, concentric 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

This species resembles C. Beanii in form, but has very different 
sculpture. 
Cocculina conica Verrill, sp. nov. 
Shell very small, thin, translucent, white, rather high, conical, with 
avery broad-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 portion 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.

Puncturella (Fissurisepta) eritmeta Verrill, 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 the extreme tip smooth and glossy. The pore is 
very small, situated very close to the apex, and it appears to be 
divided by a slight transverse septum, across the middle. The
