 decidua, vestita, castaneo-fasciata. Peristomate duplici, antice valde

A single specimen occurs in the collection, rather more tumid than 

 Ava specimens. 



3. 0. n. s. 



A distinct but not very well defined species, approaching near to 

 C. excellens, but wanting the funiculate keel of that species. Only a 

 few dead shells were collected.

A single broken specimen, but evidently a new species, recalling in 

 form G. in volvulus, only larger, and for its size a lighter shell.
