generic relations, as no Bensonia is known from Peninsular India. 

 The following is a short description : 



Shell perforate, depressed, dark fulvous, with a narrow chestnut 

 stripe below the periphery, striated, finely and closely decussated ; 

 protoconch with undulating transverse striation ; spire convex ; 

 whorls 4, convex above, the last angulate above the periphery, 

 convexly swollen below ; aperture oblique, roundly lunate ; peri- 

 stome thin, chestnut, with a white thickened lip inside. 



Major diam. 19|, min. 16, height 10| mm. 



1 This resembles B. theobaldiana, but has fewer whorls and is 

 more angulate.
