" This at first sight recalls A.birugosus, of the Khasi Hills, but is 

 larger, more globose, the ridges near the aperture more developed, 

 the aperture quite circular without the notch on the lower 

 margin. It is near A. khasiacus, but smaller; the ridges in tliat 

 species are unequal, the anterior much the smallest." {Godwin- 

 Austen.)
