Plate XXXI, figures 7, la. ' 



Shell stout-fusiform, with a rather short, regularly tapered spire, 

 a broad and deep posterior sinus, and a very short and wide canal. 



Whorls seven, moderately convex, with a wide, concave subsntural 

 hand, which is covered with regular, strongly receding, raised lines, 

 but destitute of spiral sculpture. The slioulder is rather prominent 

 where the concave band joins the convexity ot the whorl ; the rest of 

 the surface is covered with conspicuous, ]-aised, obtuse, unequal 

 revolving cinguli, separated by deep interspaces of nearly the same 

 breadth, on the spire; on the anterior part of the body-whorl 

 the cinguli become broader and Hatter, and separated by narrower 

 grooves, which are covered by numerous rather close, raised, longi- 

 tudinal lines, or lines of growth, which are less conspicuous where 

 they cross the cinguli; this arrangement produces a finely cancellated 

 structure, in which the spiral lines are much more distinct than the 

 others. Aperture narrow-ovate, continuing backward in a broad and 

 deep sinus next the body-whorl. The outer lip is thin and sharp, and 

 projects obliquely forward in a broad curve. The canal is scarcely 

 diiferentiated from the rest of the aperture ; it is short and rather 

 broad, and nearly straight. The columella is straight, with a sinuous 

 inner margin. The inner lip extends forward on the body-whorl in 

 a broad, regular curve, defined by a thin layer of enamel. Oper- 

 culum apparently wanting. The nuclear whorls are eroded, but 

 are small, regularly spiral, and without any strongly marked sculpture. 



Color grayish white, with a pale yellowish green epidermis, Avhich 

 is easily deciduous.
