A rare species of which a single imperfect specimen is before me. 

 Described from a specimen in the Cumingian collection. By error, 

 the figure is connected by lines on my plate with H. pascalia. 



H. FEISTHAMELI Hupe. PL 60, figs. 16-18 ; pi. 58, figs. 46-48 ; 

 pi. 53, figs. 8-10. 



Umbilicate, depressed, carinated, thin, light brown, paler beneath, 

 with a series of short inconspicuous reddish spots below the suture 

 and another immediately above the periphery; the space between 

 these rows either unicolored or obscurely obliquely streaked with 

 tawny ; immediately below the peripheral angle there is a continuous 

 reddish line, as in H. amazonica, but much narrower ; and the rest 

 of the base is encircled by few or many articulated reddish lines, 

 some of them sometimes almost continuous ; and there is usually a 

 wider fascia within the umbilicus. The surface is shining, and all 

 over densely obliquely strongly striate ; the strise under a lens appear- 

 ing as sharply cut undulating, frequently anastomosing little folds. 

 The spire is low, blunt at apex. Whorls 5 (apical two smooth) ; 

 regularly, gradually widening, only slightly convex, the last with an 

 acute white carina, convex beneath ; aperture slightly oblique, 

 lunar, whitish tinged with lilac inside, and faintly showing the 

 peripheral fascia, peristome very narrowly expanded, basal margin 

 subreflexed, subsinuous, columellar margin expanded in a triangular 

 plate slightly impinging upon the umbilicus. Parietal callous 

 scarcely perceptible. 



Alt. 17, diam. maj. 35, min. 31 mill. ; umbilicus 3 mill. 



Alt. 15, diam. maj. 35, min. 29 J mill.; umbilicus 4 mill.
