C. BELLULUS (Dkr.) Philippi. PL 34, fig. 5. 



Shell imperforate, elongate-conic, acute, solid, polished, grayish 

 or pinkish, with a few spiral orange lines, two on the penultimate 

 whorl ; the spaces between these lines marked with short white curved 

 lines in pairs, often forming a figure 8 shaped pattern. Whorls 

 about 8, nearly flat, the last rounded at the periphery ; spire 

 attenuated toward the acute purplish apex ; aperture small, con- 

 tracted, sulcate and iridescent within ; columella vertical, strongly 

 toothed below, Alt. 15, diam. 7 mill.

A very attractive little species. The color-pattern is quite con- 

 stant and characteristic. The interior of the mouth is more coarsely 

 sulcate than in other species, showing only about 6 folds ; the outer 

 and basal lips have a slight subraarginal porcellanous subdentate 

 thickening, which stops a little space short of the upper termination 

 of the outer lip,

Shell imperforate, elongate-conic, pointed, solid, polished, yellow- 

 ish, pink, or olive-green, with reddish or olive longitudinal lines in 

 pairs, sometimes separate on the last whorl, and usually with 

 numerous narroAV, rather obscure spiral pink or yellowish lines ; 

 sometimes with a few series of white dots on the upper part ; spire 

 conic, shorter, less attenuated than in C. bellulus ; whorls about 7, 

 scarcely convex, the last not carinate, finely striate beneath, smooth 

 above ; aperture rather large, often expanded smooth inside, lined 

 with intensely green nacre ; columella strongly toothed below.
