7. C. ZEBROIDES (E. A. Smith). 



"Shell rather solid and heavy foe its size, -.'ate, white, 

 varied with numerous close-set and slightly oblique reddish- 

 brown stripes, which are rather regular and only slightly un- 

 dulating; spire obtusely conical, while towards the apex which 

 is rather rounded and not acute, suture but slightly oblique, 

 crenulated; whorls 7, quite convex, the third and fourth from 

 the nucleus ornamented with a close granulation, the granules 

 being elongate; on the two succeeding whorls they are less 

 conspicuous, and on the last become almost obsolete; aperture 

 small, not equalling half the entire length of the shell, 

 within coated with a white opaque enamel and streaked here 

 and there rather indistinctly by the exterior brownish strip' - : 

 columella coated with a thin white callosity, which extends as 

 far as the upper extremity of the outer lip; it is a little 

 arcuated and rather abruptly but obliquely truncated at 1h- 

 basal end; peristome simple, regularly curved, and thin."
