moreover Tryon (1. c.) has some doubt about the identity of the quoted figures, I asked the 

 advice of Mr. E. A. Smith, who judged it could not be separated from C. bicolor Hinds.

This specimen is still very small but characteristic, by its large umbilicus : a few spiral 

 lirae, also recorded by Sowerby and Löbbecke, are distinctly visible.

Tryon (1. c.) declares this form to be merely a synonym of C. crenifera, but this seems 

 to go too far, it will be always separable by its lamellose ribs, vvhich in the specimen from 

 Stat. 33 are often varix-like, even nearly without exception on the last whorl, which has the 

 brown blotches below the shoulder. If specimens are slightly rubbed and if the ribs are relatively 

 thin, the distinction may be difficult. But at least it will be a well-marked variety.
