 nut, girt with a narrow band at the periphery. Whorls 6J, sub- 

 plane, forming a conic spire with acute apex ; last whorl obtusely 

 angulated, base convex, a little applanate before the aperture, very 

 shortly descending in front. Aperture oblique, lunate-rounded ;

Differs from H. friesiana (autea, p. 118) in the more elevated 

 spire, last whorl scarcely carinated, slightly angulated, base not 

 compressed, but more convex, rather inflated, peristome more ex- 

 panded. 



H. SCHMACKERI Mollendorff. PL 69, figs. 3, 4, 5. 



Shell moderately umbilicated, depressed globose, solid, obliquely 

 plicate-striate, spirally rugulose, chestnut-brown, with three yellow 

 bands, one at suture, one at periphery, the third around the um- 

 bilicus. Whorls 51, a little convex, the last inflated on the base, 

 obtusely angulated at the periphery, shortly descending in front.
