Its nearest ally appears to be C. pacifica, Gredler, from Hunan; 

 but the present species is larger, the mouth, is more quadrate, with 

 a sharp sinus just above the lamella superior. Internally the lamella 

 superior and lamella inferior do not so nearly approach one another, 

 and the lamella subcolumellaris is a trifle more conspicuous ; the shell 

 is also somewhat broader.
