ALTCvEUS. 215 



Spire de])re.ssly colloidal ; suture dei-p; apex obtuse, rather redder 

 than the remainder of the shell. Whorls 3|. convex ; the last 

 round, scarcely descending towards the mouth, very little swollen 

 at the side, and ornamented on the inflated portion for a short 

 distance with close fine costulation, which extends beneath to the 

 umbilicus and renders the shell opaque in that spot. Constriction 

 long, smooth, swelling considerably in front towards the mouth, 

 sntural tube short, about j- to ^ of the periphery of the penultimate 

 whorl. Aperture oblique, circular, deeply sinuate at the junction 

 with the penultimate whorl, and at the lower right margin ; 

 peristome double, the inner lip projecting and continuous, 

 outer lip retrorelict. Operculum horny, nuiltispiral, externally 

 concave.

 " Very near A. huviiUs, W .JManL, from Pegu, but distinguished 

 by its lower spire, wider umbilicus, nu^re sinuous mouth, and 

 especially by its high polish, In which it is only equalled by 

 A. niiidus, \V. Blanf." (Blanford.)
