" Tbis species is allied to the last described [A. succineus'] but is 

 distinguisbed by its higher spire, less marked sculpture, by the 

 strong ridge on the constriction, and by the more polygonal 

 aperture. The incision of tbe base, however, is slighter, and, in 

 this species, accompanied by a slight corresponding projection 

 beneath, which represents, on a small scale, the large ear-like basal 

 process in A. prosectus, Bens., from the Khasi Hills. The inner 

 peristome of that species also has a sliglit basal indentation within 

 the aperture." {Blanford.)
