158 A. EF. Verrill— Mollusca of the New England Coast. 
intersections of the cinguli and ribs, which are of about the same size, 
produce a pretty regularly cancellated structure, but on the last 
whorl the cinguli are more numerous and less prominent than the 
ribs. The nucleus is chestnut-brown and consists of about two and 
a half regularly increasing whorls, the apical one being very small 
and regularly coiled; this surface appears to have been minutely 
cancellated by microscopic lines. Aperture irregularly oblong or 
oblong-ovate, strongly angulated by the shoulder, and decidedly 
widest at the base of the columella. Canal short, somewhat con- 
stricted, nearly straight; outer lip thin, projecting forward below the 
shoulder, with a broad, rounded, rather shallow sinus at the middle 
of the subsutural band and a little removed from the suture. Oper- 
culum not present in the alcoholic specimens. 
Length of one of the largest specimens, 17"; breadth, 10™™ ; 
length of aperture, 10"™; its breadth, 3:5"; length of body-whorl 
to tip of canal, 12". Another more slender specimen is 15°5™™ 
long ;_8™™ broad; length of aperture, 9"; its breadth, 3™™.

PLATE XXXI, FIGURE 10. 
Shell small, short, fusiform, or subovate, with a low spire and very 
large body-whorl, forming about three-fourths the total length. The 
surface is finely decussated by longitudinal and spiral lines of nearly 
equal size. Whorls four below the nucleus, very rapidly increasing, 
strongly convex, but frequently slightly flattened at the periphery, 
and sometimes distinctly angulated at the shoulder, but more com- 
monly evenly rounded; last whorl very ventricose. Suture strongly 
impressed, often slightly channelled. The nucleus consists of two or 
three small, ight chestnut-brown whorls, with very finely cancellated 
sculpture. The apical whorl is very small and regularly coiled, 
Sculpture on the rest of the shell consists of numerous, rather fine. 
thin, regular revolving cinguli, which are separated by interspaces 
about twice their own breadth on the lower whorls, but more crowded 
on the upper ones. Two or three of the cinguli on the shoulder are 
usually coarser and a little farther apart than the rest, and the largest 
of these often forms a slight carina around the most prominent part 
of the shoulder. On the subsutural band the cinguli are less distinct 
and less regular, and often partially obsolete. Anteriorly they cover
