78. CycLOSTOMUS LAMELLOSUS. 
Shell ovate-conic, rather short, with several inequidistant, unequal, 
more or less interrupted spiral lines of brown, of which four or 
five appear on the penultimate whorl; with rather closely-set, 
sharp, elevated, transverse lamelle, which are more prominent 
at the sutures; without spiral striz, except a few ridges in the 
umbilicus; apex truncate, with the loss of two or three whorls; 
spire with the outlines quite convex ; about 3} whorls remaining, 
very convex, with a rather deep suture; aperture orbicular, 
with two peritremes, of which the outer one is narrow, auricu- 
lated above; reflected nearly into the plane of the aperture; 
the inner peritreme is rather stout, well produced, a little re- 
flected. The operculum has a spiral lamella, which has about 
44 whorls, and is but little elevated and much produced late- 
rally. Mean divergence about 50°; length, after truncation, 
0.49, greatest breadth 0.4, least br. 0.34 inch.
