192 A. K. Verrill—Mollusca of the New England Coast. 
left of the central line, so that the shell is a little one-sided, with the 
lateral slope on the right side longer and more gently sloping than 
on the left. 
Length of shell, across aperture, 20™; greatest breadth, 18™™ ; 
height, 9"™; front margin to apex, 20™™. 
The animal resembles that of Capulus Hungaricus, but the mus- 
cle by which it is united to the shell is far less developed. The ten- 
tacles are large, stout, blunt, with well developed eyes on a basal 
swelling. There are two large plumose gills situated in a large cer- 
vical cavity and attached on the left side, but extending entirely 
across the back of the neck, so that the tip of the larger gill is 
visible back, of the right tentacle. The foot is rather small, in 
the alcoholic specimen, and has the anterior corners produced into 
short obtuse auricles. The dorsal part.of the animal is moderately 
convex and does not show, in the preserved specimen, a subspiral 
form corresponding to that of the shell. The apical portion contains 
a large cluster of ova, which is distinctly visible through the integ- 
ument. 
Station 2062, near Le Have Bank, off N.8., on rocky bottom in 
150 fathoms. One living specimen (No. 35,274). It was associated 
with Primnoa reseda and other arctic forms. 
This species has not been previously recorded as living in the 
North Atlantic, south of Iceland, unless P. radiatum Sars, from 
West Finmark, be a variety of it. It was originally described from 
Okhotsk. Friele records it from off Iceland, in 290 fathoms. It 
occurs in the post-pliocene at Uddevalla, and in the Coralline Crag 
of England (as Capulus fallax 8. Wood, t. Jeffreys).

Eulimella lucida Verrill, sp. nov. 
PLATE XXXII, FIGURES 3, 3a. 
Shell rather large for the genus, long and slender, with a tall, reg- 
ularly tapered, acute spire, composed of about eleven whorls besides 
the nucleus, which is small, prominent and strongly upturned. 
The whorls are much flattened and but little convex. The suture is 
distinct, but scarcely at all impressed, especially on the upper half of 
the spire, and not very oblique. The surface is everywhere very 
smooth and polished, with a very brilliant luster, without any sculp- 
ture whatever, and with exceedingly indistinct lines of growth. 
The aperture is almost regularly ovate, narrowed posteriorly, where
