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. ' '
