" Nearly equal in size to G. himalayanus, Pfr,, from the same 

 localitv, it is distinguished from it by its form, depressed last 

 whorl, wide umbilicus, sculpture, verticality of the angle at 

 the upper part of the mediocre aperture, and by the colour of the 

 peristome. There are indications of a broad light chestnut zone 

 below the dark band at the periphery. The compressed character 

 of tlie last whorl presents a strong contrast to the subglobose form 

 of C. himalayamis in that part." (Benson.)
