oncl and most prominent forms the carina of the shoulder; the other 
three are on the anterior half; some faint additional ones appear on 
the caual ; the three preceding whorls have the subsutural and the 
sharp median carina, and usually the third carina is more or less 
exposed at the suture. Between the first and second carinae the sur- 
face is flat or slightly concave. The whorls are crossed by numerous 
thin, delicate, flexuous, regularly spaced, raised riblets, which are 
conspicuous between the carinae, and produce sharp nodules where 
they cross them. The nucleus is small, rounded, light chestnut-brown, 
minutely cancellated with microscopic lines running in two directions. 
Sinus of the lip shallow, rounded. Length, 4 mm ; breadth, 2 ujm . 
A larger specimen, with six whorls, has, on the last whorl, seven 
regular, thin, elevated, well-spaced, spiral cinguli, between the carina 
of the shoulder and the base of the canal, and additional finer ones 
on the canal ; a faint one also appears on the middle of the subsutu- 
ral band. The body-whorl is crossed by numerous, regular, distinct, 
but fine, curved riblets, or raised lines of growth, which are excurved 
on the canal, angulated and excurved at the shoulder, and incurved 
at the suture. The canal is a little curved, short, narrow, a little 
constricted at its base by the incurvature of the outer lip. 
Length, f'oO™ 111 ; breadth, 2 , 25 mm . 
Two examples were taken at station 894, in 365 fathoms, off New- 
port, R. I., 1880; another was dredged at station 994, in 368 fathoms,

Plate LVII, figure 17. 
A smaller and more slender species than the preceding, with a 
much smaller nucleus, a more acute spire, and with the carime sharp, 
but not nodulous. 
Whorls seven, angular, the lower ones carinated and shouldered. 
Body-whorl with six revolving carinae, besides one or two on the 
canal; one is just below the suture; the three largest surround the 
middle; the median one is most prominent. Between the subsutural 
and second carinae the space is concave and crossed by numerous 
elevated, thin, curved riblets, corresponding to the labial sinus; simi- 
lar but less prominent and less curved riblets cross the interspaces 
between the other carinae, but do not cross the carinae themselves.
