longitudinal striae, spire rather obtusely convex, obsoletely coro-

C. HEPATICUS, Kiener. PI. 14, fig. 65. 



Shell conically turbinatcd ; spire flat-convex, slightly chan- 

 neled ; bocty-whorl grooved towards the base ; white, brown- 

 stained at the apex. Length, 1*75 inches.

An obscure form, of very doubtful specific value.

Spire depressed, with raised apex, compressedly tuberculate ; 

 body-whorl smooth, grooved towards the base ; white, base 

 stained with violet-chestnut. Length, 1*7 inches. 



Habitat unknown. 



I have before me two specimens, agreeing perfectly with 

 Sowerby's figure. The shell differs in form, thickness and 

 coloring from all the varieties of C. lividus. 



C. UNICOLOR, Sowb. PL 14, fig. 67. 



Shell long and narrow, spire convex, distantly tuberculate, 

 body-whorl smooth, substriate towards the base ; fawn-color, 

 tinged with violet, aperture violaceous. Length, 1/7 inches.

May possibly be a variety of the preceding species.

Shell yellowish fawn-color, obsoletely banded with white at 

 the middle and upper part, sometimes the bands are not contin-

 encircled by obsolete impressed lines, stained with violet-chestnut 

 towards the base ; spire low, convex, with rather obtuse rounded 

 tubercles ; interior white, stained with light violet.
