in some cases, a distinct, subsutural raised line. Tlie fine spiral 

 lines between the carinje are rather more regular and distinct than 

 in the typical form. The nuclear whorl is a little prominent and 

 turned uj), rounded, smooth, glossy, and rather larger than in the 

 latter.

Plate XXXI, figure 15. 



Shell thin, delicate, stout-conical, with a rather high, regularly 

 tapered, acute spire, a narrow, deep umbilical ])ore, and a somewhat 

 produced base, which is sculptured by numerous (15 to 20) small, 

 spiral cinguli. 



Whorls seven, rapidly increasing, strongly angulated and cari- 

 nated in the middle. Suture distinct, very slightly impressed, 

 boi'dered below by a small, slightly i-aised, spiral ridge ; from this 

 the wide subsutural band rises, at an abrupt angle, to the carina of 

 the shoulder, forming a flat or somewhat concave upper slope on the 

 whorls. On the spire the shoulder is situated at about the middle 

 of the whorls, and the periphery, below the carina, is flattened and 

 descends nearly perpendicularly to the suture. On the last whorl a 

 second sharp carina surrounds the periphery, the space between the 

 two being a little greater than that above the first carina, the per- 

 ipheral band being here somewhat concave. Below the peripheral 

 carina the base is covered by fifteen to twenty smaller and distinctly 

 raised, thin cinguli, of which the two or three outermost are but 

 little smaller than the carinse, and separated by spaces two or three 

 times their own breadth ; near the umbilicus the spirals again 

 become a little stronger and wider apart, while over the greater part 

 of the base they are slender and very close set, the grooves between 

 being scarcely as wide as the lines; midway between the center and 

 circumference there is a low, ill-defined spiral ridge, corresponding 

 to the anterior einus of the lip; the innermost spiral line forms a 

 thickened border for the umbilicus. The spaces between the carinse 

 are crossed by numerous, very delicate, flexuotis, raised riblets, 

 which are close and very regularly spaced, and rather more promi- 

 nent on the last whorl than on the spire; those on the subsutural
