" The yoiiDg of C. mlagiricum preserved its distinctness from 

 C. Jerdoni in the same condition by its sculpture, colour, the 

 depression of the spire, the broad flattening observable above 

 the shoulder of the whorl, the angulation of the shoulder, the 

 excavation of the perioniphalum, its compressed angulated edge, 

 and by the blue colour of the interior, \\ hich is bordered with 

 chestnut in the young, but gradually gives place to the orange of 

 the peristome in the adult example of C. nilagiricum, while She 

 whole of the interior is wliite in both states of G. Jerdoni. The 

 spiral striae are not very conspicuous on the underside of 

 C. nihgiricuni, and are entirely discontinued at a short distance 

 from the periphery, the region of the umbilicus being smooth. 

 In most of the allied species the umbilicus audits neighbourhood 

 are pale, but in this species the dark chestnut ground colour of 

 the shell extends over the whole exterior surface where not broken 

 by flecks or streaks of whitish." (Benson.)

Original description : — " Shell umbilicated, turbinate, keeled ; 

 sculpture, apex smooth and shining ; five distinct lirate ribs run 

 contiguous to the suture on the lower margin of the whorls, 

 commencing with the third whorl ; these have two finer thread- 

 like ribs between them, and similar fine liration is continued above 

 and on the lower surface of the shell, crossed by strong lines of 

 growth on the epidermis. Colour umber-brown, marbled with 

 madder-brown, given off from a few strong spots of this colour 

 next the suture ; tiie peripheral rib is dashed with white at 

 intervals. Spire conoid, sides flat, apex sharp ; suture shallow ; 

 whorls 5, subconvex, the last sharply keeled, forming a strong 

 rib ; aperture oblique-ovate, ample on the outer margin, grey 

 within ; peristome white, well thickened in mature shells, sharply 



reflected.

" In these eastern liills this form takes the place of C. zehrinus 

 of the Khasi Hills &c., but it is much larger, the spinil ribbing is 

 much stronger, the whorls are more convex, and it is more openly 

 umbilicated.
