This species is intermediate between C. silckimensis and 

 C. khislana, but it has the last whorl proportionately much wider 

 than the latter, nearly equalling half of the entire length of the 

 shell. The shell is firmly plicate-striate and decussated. Two 

 specimens in the British Museum measure 16x6-5 mm.
