" With a general resemblance in form to G. indicus, Desli., it 

 will be at once distino;uishod by the absence of a keel or acute 

 spiral ribs, by tlie wider umbilicus, less developed peristome, and 

 more elevated form. The very gradual ai'cuation of the coluiuellar 

 lip is also an essential character, detracting from the uniformity 

 of the cii'cular aperture. The sinus observable at this part, 

 impinging on the plane of the aperture, is also conspicuous in 

 C. indicti,s. 



" A variety occurs in which the shell is of a pale buiF colour, 

 darker towards the apex, the bands and markings being obsolete, 

 and the colour of the peristome being equally vivid with that of 

 the typical shells. Another thinner variety occurs in which the 

 interior coloured lip is not present." {Benson.)
