Aperture diagonal, lunate-elliptical ; peristome expanded, thickened, 

 purplish, margins joined by a thin callus, columellar margin dilated.

Differs from H. Caspar i in being smaller, higher, whorls more con- 

 vex, the last one inflated, obtusely angulated (not carinated), in the 

 narrower umbilicus and the bands.

H. (HADRA) BOURKENSIS E. A. Smith. Unfigured. 



Shell narrowly umbilicated, depressed-globose, sub-thin, shining, 

 yellowish, ornamented with two rufous-brown zones above the mid- 

 dle ; whorls 5i, a little convex, rather slowly increasing, separated 

 .by rather profound suture, striated by delicate growth-lines, min- 

 utely granulated above, the- last a trifle descending in front, rounded 

 at the periphery, more shining below than above, scarcely granu- 

 lated ; spire short, obtuse at apex. Aperture wide, lunate, pale 

 brownish, ornamented above with a zone of darker; peristome thin, 

 pale, slightly expanded, columellar margin dilated and reflexed, half 

 covering the umbilicus. Alt. 14J, greater diam. 20, lesser 17 ? mill.; 

 aperture, length 10, width 9? mill. (Smith, Annals and Mag. N.

 This species, in general appearance, is considerably like H. 

 Broughami Angas and H. Angasiana Pfeiffer. The banding is 

 exactly the same as that of the latter species, but its epidermis is 

 yellower. It is also distinguished by its less globose form, smaller 

 body-whorl, its more glossy surface, especially the under surface, 

 the much smaller umbilicus and much thinner peristome, and a dif- 

 ferent granular sculpture on the spire. H. Broughamilbas an addi- 

 tional brown band below the periphery, has a finer granulation 

 above, the umbilicus is more open and surrounded by a colored 

 zone, and the aperture is wider. H. Stutchburyi Pfr. is a smaller 

 form, more finely granular above, and in the type the spiral zones 

 are much narrower than in the present and the two above-named 

 species.
