"A variety of it, differing sliglitly, which is nmch hirger and 

 more depressed in form, but which iii the creiiate peristome and 

 in form of constriction is the same, occurred in the valley of the 

 Dikrang and in the Yetai Eavine. This variety measures in alt. 

 0*18 [4'5 mm.], major diam. 0-i:5 in. [6-25 mm.]." (Godwin-

Orif/iitcd description : — " Shell depressedly and glohosely conoid, 

 very openly umbilicated ; sculpture: costulation fine, somewhat 

 irregular and distant as it approaches the termination of the 

 sntural tube, it is then close and sti-ong. Behind the aperture it 

 is quite smooth. Distinct longitudinal stria) are to be seen on the 

 u])i)Hr whorls; colour dull pale ocliraceous; spire low, apex small, 

 papillate; sutui-e much impressed; whorls 4g, the last swollen, 

 smooth portion behind aperture short with no ridges; aperture 

 ciicular, slightly angulate above near suture ; peristome creiuilated 

 on the outer margin, four de])ressions with strongly defined inter- 

 mediate processes, straight above, well rounded on the columellar 

 side; operculum muliispiral, very concave, and outer margin 

 turned inwards. 



" Major diam. 0-75 [? 7-5], alt. axis 0-3 [? 3]. Size of largest :

 strong and close-set next the sutural tube, becoming gradually 

 finer posteriorly; colour bleached; spire high, conical, apex tine: 

 suture impressed, sutural tube very long ; wlioi'ls 4|, well rounded 

 on the sides, the constriction is short ; aperture ovately circular, 

 subvertical ; peristome double, deeply and sharply crenulated, 4 

 deep channels running backwards separated by V-shaped barriers,

" Tliis maybe compared with A. vesica from the same great 

 valley, but its sjure differs and the crenulation is sharper and finer. 

 It may also be compared with A.lohitensis from Brahmakuiid, but 

 the difference is quite specific." {Godivin- Austen.)
