242 A. FE. Verrill—Mollusca of the New England Coast. 
small smooth callus. The aperture is oblique, nearly circular, 
encroached upon a little by the body-whorl. The lip is slightly 
thickened, with the margin rounded. In some specimens there is a 
slight, angular, posterior sinus, at the suture, and sometimes the ~ 
inner lip is a little thickened in the umbilical region. Color of all 
our specimens white, but none of them appear to have been living, 
although many are fresh and have a polished surface. 
Greatest diameter, 2°5™"; height, 1:5" ; diameter of the aperture,

Off Cape Hatteras, station 2109, in 142 fathoms (No. 35,731), about 
thirty specimens. 
This species bears some resemblance to &. anomala D’Orb., but is 
peculiar in having the whorls of the spire concealed, or nearly so, by 
the last whorl. 
Ethalia multistriata Verrill, sp. nov. 
Rotella striata? D’Orbigny, Moll. Cuba, atlas, pl. 18, figs. 29-31. 
This shell, although resembling in most respects that figured by 
D’Orbigny, differs in being more depressed, with a lower spire and 
less prominent base. The spiral lines are much finer and more. 
numerous, and the inner lip is distinctly thickened opposite the 
~ umbilicus. 
Shell small, much depressed, with the spire rising but very little 
above the body-whorl, and with the base distinctly flattened. 
Whorls about three and one half, separated by a distinct and slightly 
impressed suture. The upper side of each whorl is depressed, but the 
periphery is very convex and obtusely rounded. The nuclear whorl 
is moderately large, smooth, translucent, and regularly coiled. The 
entire upper surface, below the nucleus, and most of the base, are 
covered by very numerous fine, impressed, revolving lines, with 
interspaces which are a little wider than the lines themselves. On 
the inner half of the base, around the umbilicus, the spiral lines are 
obsolete. Just below the suture there is a stronger groove or slight 
depression, defining a small, subsutural, slightly raised ridge. The 
surface is also covered with very fine, but distinct, impressed lines of 
growth, which, in crossing the spiral lines, give them a slightly wavy 
or punctate appearance, and sometimes produce a minute and feeble 
reticulated structure. The aperture is very oblique, broader than 
long, with the anterior border somewhat flattened, the outer side 
very convex, and with a slight, angular, posterior corner, or sutural 
sinus, below which the body-whorl projects slightly into the aperture,
