PuatE XXXI, FIGURES 7, 7a. 
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 subsutural 
band, which is covered with regular, strongly receding, raised lines, 
but destitute of spiral sculpture. The shoulder is rather prominent 
where the concave band joins the convexity of the whorl; the rest of 
the surface is covered with conspicuous, raised, 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 flatter, 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 
differentiated 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 sinall, regularly spiral, and without any strongly marked sculpture. 
Color grayish white, with a pale yellowish green epidermis, which 
is easily deciduous. 
Length 22™™"; greatest breadth, 117”; length of aperture, 14™™ ; its 
breadth, 5™™.
