" Tliis species is allied to the last described (.4. succineus), but is 

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

 strong ridge on the constriction, and by the more polygonal ajier- 

 ture. The incision of the base, however, is slighter, and in this 

 epecies accompanied by a slight corresponding projection beneath, 

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

 in A. ])rosectus, Bens., from the Khasi Hills. The inner peristome 

 of that species also has a slight basal indentation within the 

 aperture." 



'• I am indebted for a few perfect specimens of this species to 

 Captain Ingram, who found them upon the western side of the 

 Arakan range. I obtained one imperfect specimen at 8houkbeng 

 on the Prome and Tongoop road, close to the summit of the hills.''
