Allied evidently to H. brevidens, but has a wider umbilicus and 

 lacks the basal tooth.

 This species described in P. Z. S. 1873, p. 207, from Borneo, seems 

 to belong here rather than in Fruticicola or Dorcasia. 



H. BREVIDENS Sowerby. PI. 55, figs. 37, 38, 39, 40, 41. 



Shell depressed-subglobose, narrowly, partly covered umbilicate,. 

 the upper surface only slightly convex, lower surface very convex ; 

 light brownish horn-color, with a narrow chestnut supra-peripheral 

 band, which ascends the spire just above the suture, becoming dif- 

 fused on the inner whorls. Lip narrowly but evenly and flatly re- 

 flexed, the basal margin with a small tooth. 



The shell is thin, light, delicately substriate, covered with very 

 closely, regularly placed, short hairs, on the upper whorls and apex 

 the scars alone remaining. Whorls 4?, the last a little descending 

 in front, swollen below, bluntly subangular around the very narrow 

 umbilicus, not constricted behind the lip except in the immediate 

 vicinity of the umbilicus. Aperture lunar, somewhat oblique, flesh- 

 colored inside, terminations of peristome remote. Alt. 12J, greater 

 diam. 21 mill.

The low spire, swollen base, nearly closed umbilicus, and cloth- 

 ing of fine hairs or hair-scars are the more prominent characters of 

 this shell. 



H. SANZIANA Hombron & Jacquinot. PI. 37, figs. 51, 52, 53, 54. 



Shell umbilicated, globose-depressed, solid, striatulate and all over 

 granulated, a little shining, reddish, with a chestnut peripheral band 

 and an obsolete one above and below ; spire depressed-semiglobose, 

 apex plane, wide ; whorls 5, a little convex, sensibly increasing, the 

 last scarcely descending in front ; periphery subangular, base con- 

 vex ; aperture nearly vertical, subangulate-lunate, bluish-white in- 

 side. Peristome expanded, brown-edged ; basal margin a little
