"It is related to the Burmese A. tanbonaJis and to A. stranyu- 

 latus, Hutton. Inferior in size to the former, it is easily distin- 

 guished by its sculpture and by the peculiar development of the 

 outer lip at its insertion and base, while the narrow columellar lip 

 gives an appearance of artificial truncation to the peristome at 

 that part. In the variety the internal lip is not developed. The 

 margins of the whorls in the operculum are not conspicuously 

 raised as in A. wnbonalis." (Benson.) 



Godwin-Austen records a variety — unnamed — from Cherra 

 Poonjee, in the Ponsonby collection, whicb is smaller than the 

 usual typical form, and tliough quite similar in shape, shows a 

 decided tendency to crenulation on the outer margin of the peri- 

 stome ; a similar tendency he observed in other species. 



Some specimens from I'eria Ghat he noted being as much as 

 8 mm. in major diameter, varying much in size even from this 

 locality, fully-grown specimens being only G mm. Prom some 

 places'all are small ; G. Nevill distinguished them as var. minor. 



Prom Eywuk, at the foot of the Garo Hills, he found the 

 form to differ considerably in having a tendency to a crenulate 

 peristome.

Original description: — "Shell very openly umbiiicated, de- 

 pressedly conoid, covered with a strong epidermis ; scul])ture : 

 costulation strong, very close and regular on upper whorls, still 

 more so next sutural tube, where 21 ribs can be counted, the tube 

 is rather short ; colour ochraceous with a green tinge ; spire low, 

 apex small ; suture well impressed ; whorls 4, tumid, sides 

 rounded, the distance from the constriction to the aperture is not 

 great, and is crossed just behind it by a well-defined ridge of 

 regular breadth ; aperture circular, obtusely angulate on upper 

 inner margin ; peristome simple, double, not reflerted ; operculum 

 black, multispiral, concave, whorls rougli and raised above
