Original description :— " Differs from the described form from 

 Arakan [i.e. inciranu^, in the mouth being larger, and there is a 

 tendency to undulation on the outer margin of the peristome, 

 p-enerally two notches are present. 



" Major diameter 0"24" [6 mm.], minor diam. 0-24" [6 mm.] ; alt. 

 0-16" [4, mm.]; diam. of aperture O-ll" [2"75 mm.] ; suturai tube 

 009" [2-25 mm.]." (Gochvin-Austen.)

 Burrail Range (7000 ft.), IS'aga Hills (Godwin-Austen); Lhota 

 JSfaga Hills, Asalu. 



In 1893 Godwin-Austen, after comparing this shell with typical 

 A. ingranii, became convinced that it was quite distinct and gave 

 it the specific name of distinctus. Another form, from the Dafla 

 Hills, originally considered to be a variety' of ingrami, was like- 

 wise raised to specific rank under the name of macgregori, 



A variety is recorded from Sadia, collected by M. Ogle, on 

 page 363 of the same work and figured on pi. 137, figs. 2, 2 a, 2h. 

 It is stated to differ from the type in its flatter depressed shape, 

 rounded aperture, and the shorter distance from it to the 

 suturai tube.
