The Indian Museum is indebted to the late Dr. Oldham for several fine speci- 

 mens of a form of this handsome species collected in Assam by Mr. Masters ; they 

 agree exactly in every respect with the type form, having light yellow-coloured 

 apertures, &c., only they are a trifle larger in size ; it is probably one of these speci- 

 mens which is figured in the ' Con. Indica,' pi. xxxiii, figs. 1, 2 (Khasi Hills) ; it 

 differs widely from Mousson's Javan species, by the acutely angled periphery, by its 

 much more open umbilicus, and by the broad basal band, &c. A fine variety of this 

 species, C. suhlcevigatus, var. pealiana, occurs in the Naga Hills.^ 



Type from Upper Burma : axis 29, diam. 46 mm.
