Differs from typical albizonatus by the smaller size, by having one 

 whorl less, a stronger keel, and it wants the white keel-band of 

 albizonatus. The surface is densely punctulate or granulose, below 

 as well as above. This is the most strongly carinated of the chain of 

 white Ceylonese Amphidromes, which has its opposite extreme in the 

 rounded A. ceylanicm. Named for M. E. Simon, the araneologist, 

 who collected the types in 1892, while exploring Ceylon for spiders. 

 Fig. 17 is a copy of the type figure, representing a specimen from 

 Galle. Fig. 18 was drawn from a shell collected at Udagama by 

 Mr. Collett. It was one of these that I dissected. 



A. PHYSALIS (Benson). PI. 1, fig. 13. 



Shell nearly covered perforate, ovate-conic, rather thin, obliquely 

 striatulate, whitish, glossy ; spire conic, the apex obtuse, suture 

 lightly impressed. Whorls 5^, somewhat flattened above, the first 

 granulated, the rest decussated with minute spiral striae, last whorl a 

 little swollen, four-ninths the length of the shell, usually angulate at 

 the periphery. Aperture ample, oblique, truncate-pyriform ; peri- 

 stome expanded, the margins reflexed, joined by a thin callus ; colu- 

 mellar margin very broad above, appressed, obliquely lightly im- 

 pressed, nearly covering the narrow, pervious umbilicus. Length 

 27-28, diam. 16-17, aperture 14-16 mill. (Bens.)
