"^. huniilis resembles somewbat the minute A. armillatus, B., 

 but differs in the very much greater distance to which the strongly 

 marked costulation upon the tumid portion of the last whorl is 

 carried back from the constriction, the distance being in both 

 species proportional to the length of the sutural tube. A. humilis 

 is futher distinguished by its longer constriction, by the descent 

 of the mouth, and the greater tumidity of the last whorl. The 

 coloui', as in many Alyccei, is probably not quite constant, some 

 specimens being white and translucent." {Blanford).

Original description : — " Shell subobtusely perforated, turbinate, 

 pale amber or white, smooth, finely ribbed o)i the swollen portion 

 of the last whorl, with sign of subdistaut ribbing behind the 

 termination of the sutural tube. Spire conoid, apex blunt, suture 

 impressed. AVhorls 4, rounded, last very slightly swollen, then 

 moderately constricted, swelling again in a low ridge, somewhat 

 recurved. Constriction smooth ; sutural tube rather short, tine ; 

 auerture subvertical, round. Pei-istome deeply waved within ; 

 salient angles between the undulations nodose; inner lip continuous, 

 outer reflected, considerably near the umbilicus.
