" At first sight this shell might be taken for a variety of 

 C. shevaroyanibni, Beddome, from the Siilem district, to wliich it 

 is very nearly allied. It is, however, smaller, differs in the 

 relative proportion of height to breadth (a specimen 1 have of 

 C. shevaroijanum measures : alt. 2-3, lat. 3 mm.), and is of a 

 thinner texture. The cariiiations above are also not so strongly 

 marked, while the lira? in the umbilicus are stronger and appear 

 to be more numerous." {Sylces.)
