I have not seen this species, and the type is said to be lost from 

 Benson's collection in the Cambridge museum. Perhaps it was not 

 returned by PfeifFer, and is now in Dohrn's collection. 



It resembles A. sylheticus in the globose base and groove at root 

 of the columella, but differs in being stouter in form, two-banded be- 

 low, and with a brown streak behind the lip, which is said to be pale 

 lilac colored. Nevill mentions but does not describe a var. gfflbosa 

 from Chittagong, probably identical with the following: 



Var. vicarius Fulton. PI. 62, figs. 67, 68, 69. 



Differs from A. sinensis " in being not so broad in proportion to 

 its length and in coloration. It is broader than sylheticus, and in- 

 stead of being an uniform green color, it is yellow, with two (some- 

 times three) more or less distinct dark brown bands encircling the 

 lower part of the last whorl. This variety varies a great deal in size 

 and form. I give here dimensions of two specimens out of a series 

 in the British Museum : length 33, diam. 17 mill.; length 21, diam. 

 14 mill." (Fulton}.
