sage, and in 20 fathoms Gulf St. Vincent. Dredged dead

large and small, mostly worn; in 55 fathoms off Cape Borda, 
57, up to an inch long; in 110 fathoms off Beachport, 16 in: 
moderate condition; in 130 fathoms off Cape Jaffa, 6 very 
poor; in 200 fathoms off Beachport, 1 fragment. It appears 
to live at about 20 fathoms, not in the very shallow nor in the 
very deep water. Some of the shells from 40 fathoms have 
axial lines, about 16 in a whorl, which seem like cracks in the 
deeper layer of the shell substance, and become visible as the 
outer scabrous covering is worn off. 
On the Base there may be as many as twelve distinct spiral 
lire, or only three or four obsolete threads near the periphery. 
Generally three or four larger threads encircle the middle 
third of the spire-whorls; sometimes twelve or fourteen of 
nearly equal size are distributed over the whorl. The peri- 
pheral cord may be very stout, and project considerably beyond 
the suture, so imbricating the whorl below; or it may not 
project at all, and the whorls may be uniformly sloping or dis- 
tinctly convex.

Kiener in his description and plate represents the species 
as quite smooth. But actually besides the two prominent 
keels there are seven to ten spiral striz, generally one more 
above the carina than below. In addition there are, crossing 
these, very fine lamellar striz, following the curve of the-
