Three of the specimens arc cjuite alike, (lilTcrinL;- onh- in size, on account of afje, so I 

 have described them as tlie tyjic; the fourth is much more developed in sculpture, so uiuch 

 that I was in dtiubt if it ought not to be seixu'ated, the spirals are stronger, there is a spiral 

 in the excavation, on the contrary the last whorl has at all only 12 si)irals, besides that below 

 the suturi\ which is weaker, and I fmd very fuie s[)irals in the interstices, the last rib before 

 the i)eristome is strongl)- developed; as it is however not impossible that the other spcciuiens 

 are not (piite developed, I think the other differences ma)- be individual; unlorlunalely the 

 nucleus of the fine specinien is worn, the outer layer being lost, so I could not make out, if 

 it has been identical.

Tryon unites C. cohnnbelloides Reeve with this species, but Boettger (Nachrichtsbl. der 

 Deutschen INIal. Gesellsch. 1895, p. 19) has clearly pointed out the differences between the 

 two species.

The spire of the only specimen is broken, so the shell has only 4 whorls and the iden- 

 tification is somewhat doubtful.
