the shell. One of the spiral lines just above the suture and one or 
two of those at the shoulder are stronger than the rest. Between 
the ribs the revolving lines are roughened by fine lines of growth. 
The four nuclear whorls (fig. 2a) aré evenly rounded and in strong 
contrast with those that follow them. The first one is very minute, 
forming a very acute apex; the surface is finely cancellated by two 
sets of lines running obliquely in opposite directions. The aperture 
is elongated and rather broad in the middle ; the outer lip has a deep 
and broad posterior sinus, below which it projects strongly forward 
and is regularly arched to the base of the canal; the canal is narrow, 
nearly straight, slightly prolonged ; the columella is straight and 
tapered, with its inner edge forming a slightly sinuous curve; the 
inner lip is smooth and polished, with a thin coat of enamel which 
extends somewhat forward in a regular curve on the body-whorl. 
The color is white with a pale grayish tinge, with the exception of 
the nuclear whorls, which are deep chestnut-brown.

PLATE XXXI, FIGURES 3, 3a. 
Shell small, delicate, fusiform, with an elevated and very acute 
spire and a slightly elongated, straight canal. Whorls angulated 
and turreted, sculptured with ribs and revolving lines, which form 
rows of small, sharp nodules at their intersection around the per- 
iphery, and especially at the shoulder. Whorls about four, below the 
nucleus, which is unusually elongated and composed of four pale 
chestnut-colored whorls, which are finely and regularly cancellated. 
The apical whorl is very minute and prominent, giving the spire a 
very acute tip. The nuclear whorls increase rapidly and regu- 
larly in size, and are regularly rounded. The sculpture passes 
somewhat gradually into that of the next lower whorl, which is 
distinctly ribbed and carinated, with a single row of sharp tuber- 
cles around the middle. The lower whorls of the spire have the 
shoulder at about the middle, and below it two or three raised cin-
