lacking) just above the periphery. Surface hardly shining, rather 

 coarsely obliquely striate, seen under a lens to have excessively fine 

 close spiral stria?. Spire low-conic ; sutures impressed ; whorls 6, 

 somewhat convex, slowly increasing, the last not descending hi 

 front. Aperture oblique, white and showing the band inside. Per- 

 istorne somewhat expanded, decidedly widened by a white callous 

 thickening or rib within, margins all curved, converging, the upper 

 margin scarcely expanded toward its insertion. Umbilicus funnel- 

 shaped, penetrating deeply. Alt. 15, diam. 24 mill.

Allied to H. herrmannseni, but smaller, having a brown band ; 

 the last whorl not descending at the aperture, and the peristome 

 strongly labiate or calloused within.

Shell smaller (diam. 22 mill.), less depressed, ornamented with a 

 rather wide deep brown peripheral zone ; whorls 5 ; aperture less 

 oblique ; umbilicus minute ; last whorl subangular at its beginning. 

 Form and color recalling the Formosan H. succincta H..Ad. (Ancey.)

Shell umbilicated, depressed, carinate, rather thin, seen to be 

 very minutely granulated, under a lens ; oily-shining, pale fulvous ; 

 spire little elevated, apex obtuse ; whorls nearly 5, nearly plane, 

 regularly increasing, the last descending only a trifle in front, sub- 

 inflated under the rather acute carina ; umbilicus moderate, pro- 

 found ; aperture littl oblique, subangularly lunar, peristome whit- 

 ish, margins scarcely converging, the upper narrowly expanded, 

 basal subreflexed, columellar shortly ascending, subdilated above.

This form I have not seen. It belongs either in the present group 

 or in Cathaica. My reason for not placing it next to H. pyrrohozona 

 (the type of Cathaica) is that the surface is granulated, not simply 

 striate as in the species named.
