Close to A. contrarius in having a nodule at the posterior ajigle of 

 the aperture, but, as Fulton says, it " differs in coloration, being 

 white above with two dark brown and two pale yellow bands on the 

 last whorl, the topmost yellow band being continued above ; lip and 

 columella pink." I think it would be more justly ranked as a variety 

 of A. contrarius. 



Schepman's single young specimen from Sumba Island may not be 

 this species, as the characteristic tubercle at the mouth angle is not 

 developed until maturity. 



Var. albolabiatus Fulton. PI. 65, fig. 31. 



" Differs from suspectus in being larger, in having a white lip and 

 columella, and only two dark-brown bands on last whorl, the upper 

 being continued at the suture of the upper whorls." (Fulton.) Timor.
