 striate, silky, pellucid, chestnut-corneous. Spire turrite, the 

 apex rathor obtuse, suture impressed, whitish, subcrenulate. 

 Whorls 9, a little convex, the last one not one-third the length, 

 rounded at base. Columella a little arcuate, white-calloused, 

 somewhat twisted, obliquely truncate at the base of the sub- 

 rhombic-semioval aperture; peristome simple, unexpanded, 

 ihe right margin regularly arcuate. Length 22, diam. 7 mm. ; 

 oblique length of aperture 7.5, width 4 mm. (Pfr., from spec,

The initial half whorl is smooth, the next two whorls closely, 

 very regularly striate vertically. Then the coarser, post- 

 embryonic sculpture begins (pi. 10, fig. 4). The striation is 

 rather sharp but uneven, and the striae are strongest at and 

 near the suture, decreasing downwards. It resembles G. noti- 

 gena somewhat, but the early whorls are not attenuated, and 

 there are 2y 2 embryonic whorls. 



Col. Beddome remarks: " I found the smaller variety very 

 abundant on the top of the Myhendra Hill (Ganjam). The 

 larger variety, found near Calcutta and in central India, and 

 well figured by Hanley, is a rare shell. It has a shorter and 

 blunter apex and fewer whorls than G. vandalica, but speci- 

 mens of that species sometimes do duty for it in collections."
