The color-pattern in the several specimens before me is quite con- 

 stant. The superior. part of the last whorl is convex, then sloping, 

 giving the periphery the suggestion of an angle ; and this appear- 

 ance is often visible at the aperture. 



H. KUIINI Pfeiffer. PL 59, figs. 55-57. 



Umbilicate, depressed, thin, striatulate above and below rather 

 densely granulated, diaphanous, pale reddish-corneous, with a sub- 

 sutural zone of large spots (anteriorly bipartite), then some narrow 

 obsolete bands, and below the periphery ornamented with an inter- 

 rupted reddish fascia; spire a little elevated, apex plane; suture 

 profound; whorls 41, convex, regularly widening, the last angular 

 above the middle, the angle vanishing anteriorly, a trifle descend- 

 ing, convex beneath ; aperture slightly oblique, lunar, submargari- 

 taceous inside ; peristome thin, the margins distant, right margin 

 very slightly expanded, basal slightly flexuous, very narrowly re- 

 flexed, columellar margin reflexed in a triangular plate, not closing 

 the narrowly perforating umbilicus. (Pfr.)

Closely allied to the preceding, but granulate beneath, and 

 (apparently) lacking spiral lines there. 



H. ANDICOLA Pfeiffer. PL 58, fig. 49. 



Umbilicate, depressed, thin, granulate above and beneath, opaque, 

 whitish-corneous, banded with a number of reddish interrupted, or 

 spotted zones, the interstices flammulate with red ; spire plane ; 

 whorls 4, convex, the last dilated, rounded ; aperture rounded- 

 lunar ; peristome thin, margins joined by a thin callous, upper mar- 

 gin narrowly expanded, basal slightly reflexed, columellar dilated, 

 reflexed, half covering the narrow umbilicus. (Pfr.)
