A, E. Verrilli—Mollusca of the New England Coast. 173 
cal whorl is very small, closely and regularly coiled, largely covered 
by the next whorl, which is at first smooth, then shows delicate spiral 
lines which gradually become stronger; the next two whorls are 
covered with rather strong, elevated, spiral cinguli, unequal in size 
and obtuse at summit, separated by interspaces of about the same 
width. The first whorl below the nucleus has four or five cinguli ; 
the next has one or more smaller lines in each of the interspaces be- 
tween the primary ones; the succeeding whorl has about ten to 
twelve prominent cinguli, with some additional ones of smaller 
size; on the lower whorls the cinguli become much more numerous, 
covering the whole surface, the most prominent surrounding the 
periphery and having three to five smaller ones between them; just 
below the suture the cinguli are often less prominent than elsewhere, 
and are rendered wavy by transverse ribs. The two upper whorls, 
below the nucleus, are generally destitute of transverse ribs, or have 
them but slightly developed; on the succeeding whorls they become 
somewhat more conspicuous ; they are broad, low, rounded at the 
summit, nearly straight, but a little receding just above the middle 
of the whorls, and are evenly spaced, having concave intervals about 
equal to their own breadth. On the lower whorls there are about 
twelve to fourteen of these ribs. Both the ribs and interspaces are 
equally crossed by the revolving cinguli, and their entire surface is 
covered by fine, close, raised or slightly lamelliform lines of growth. 
Outer lip sharp, thin, rather evenly rounded, contracted at the base 
of the canal, which is moderately long, narrow, twisted, and a little 
recurved. Aperture long-ovate, rather narrow, regularly incurved 
on the inside. Columella strongly bent and spirally twisted in a 
sigmoid curve. Opereulum broad-ovate, obtusely rounded at the 
anterior end, with the nucleus situated slightly within the margin of 
the inner edge, from which the lines of growth diverge in a sub- 
spiral manner. There is often a slight notch on the inner margin, 
just back of the nucleus. Epidermis inconspicuous. Color, in alco- 
hol, pale pink or pinkish white, translucent, usually white or 
yellowish white when dried. 
Length of one of the larger specimens, 21"; breadth, 9"™"; length 
of body-whorl and canal, 14"; length of aperture, 10"; its breadth, 
4". Other specimens are decidedly stouter than the one measured,
