" This form was sent to uie as A. hosei, G.-A., var., but it is 

 decidedly diiferent from that species, which has a more elevated 

 spire, the last whorl much less tumid, the outer peristome much 

 broader and almost auriculated at the insertion, the columella 

 deeply sinuate, paler colour, etc. In fact the nearest relation of 

 the new species is none of the Bornean Ahjccd, but A. jar/ori, 

 V. Mart., of Java. It differs from the latter by greater size, half 

 to one whorl more, the deeper constriction, the last whorl hardly 

 deflected and therefore the less oblique aperture." (Moellendorff.)
