'• In the thickened rounded form of tbe peristome this species 

 assimilates to A. conicus, !mt the minute notches on the inner 

 imii'gin are peculiar and unlike what is seen in any form I am 

 acquainted with. It seems intermediate between the above 

 \_A. stoliczhti] and ^4. diagonius." (^Godivin- Austen.)

Original description: — "Shell globosely conoid, solid, well 

 umbilicated ; sculpture : very fine, close transverse costulation near

 distant longitudinal liration also at this ])art ; a few distant in- 

 distinct lira; cross tbe smooth portion in front of the constriction; 

 colour whitish stone; spire fairly high; suture well impressed; 

 whorls 4, sides well rounded, the last very tumid : aperture nearly 

 -circular, subvertical on the columellar side; peristome double, very

//ah. India: Sihbiuu, Abor Hills {Oalces). 



■• The sculpture, particularly that of the swolleii portion of the 

 last whorl, near the sutural tui)p, is characteristic of several 

 species of Ali/cm of the Abor Hills.'' (Godivin- Austen.)
