yellow-greenish or blackish, the apex eroded, yellow ; and there is a 

 streak of yellow on the base just below the columellar teeth.

This species is similar to C. gallina in form and characters of the 

 aperture. It is lusterless, purple or black, the apex usually eroded, 

 orange-colored ; the teeth of the columelia are white ; and there is 

 never a yellowish streak at the base, as in the var. tincta of the last 

 species. The whorls are spirally lirate, sometimes smooth except on 

 the base, sometimes strongly lirate above. The suture is margined 

 below by an impressed line, and by elevated, foliaceous incremental 

 lamella?. This last feature may almost always be detected, although 

 sometimes but very slightly developed.

One of the most abundant mollusks of the Californian Coast. The 

 shell never shows the longitudinal folds and stripes characteristic of 

 typical C gallina, nor has it the basal yellowish streak of the smooth 

 var. tincta. The foliated subsutural margin is characteristic, also, 

 though not always developed. 



C. BRUNNEUM PhilippL PL 27, figs 36-38. 



Shell imperforate, conical, solid, russet-yellow, brown, orange- 

 colored or deep crimson ; spire conic ; sutures deeply impressed ; 

 whorls about 7, convex, smooth, obliquely lightly striate, the last 

 sometimes obsoletely undulated or plicate below the suture ; base de- 

 pressed, deeply concave in the center ; aperture very oblique ; 

 columelia one or two toothed near the base ; umbilical callus white ; 

 place of the umbilicus deeply excavated.

The smooth surface and the color of this species will distinguish it 

 from any of its allies. It is according to Lischke found upon the
