H. PUDICA Pfeiffer. Unfigured. 



Narrowly umbilicated, trochiform, rather thin, striatulate, having 

 close, forward-descending strise above, beneath decussated with sub- 

 concentric striae ; buffish-fleshy ; spire conic, rubescent above, apex 

 rather obtuse ; suture light ; whorls 5, slightly convex, the last not 

 descending, subacutely cariuated in the middle, more convex on the 

 base, having a single chestnut band at the carina ; somewhat tumid 

 in front. Aperture very oblique, rounded-subrhombic ; peristome 

 subroseous calloused, upper margin a little expanded, basal flexuous, 

 reflexed, dilated above the umbilicus, provided with a nodule within, 

 at the insertion. 



Alt. 14-15, greater diam. 22, lesser 19 mill. (Pfr.)

H. LEINARDIANA Crosse. PI. 11, figs. 13, 14, 15, 16, 17, 18, 19. 



Half-covered umbilicate, depressed -trochiform, solid but rather thin, 

 about equally convex above and below the acute peripheral keel. 

 Surface striatulate and covered with a close, fine sculpture of for- 

 ward-descending wrinkles, becoming concentric beneath. Spire low- 

 conic, apex obtuse. 



Whorls 41, rather convex, the earlier red or purple (rarely 

 whitish), the remainder white or buff, with a brown band above, 

 usually wide or split into two or three, and a broad band below the 

 white or buff peripheral zone ; the suture is bordered below with white 

 or buff. The upper surface sometimes has a faint bluish band, and 

 scattered purplish dots. 



Aperture oblique, vividly banded inside; peristome narrowly ex- 

 panded, pink at the terminations of the bands and at the root of the 

 columella ; basal and columellar lips reflexed, the latter straightened, 

 having a callous fold in the middle, and dilated half over the rather 

 large umbilicus. Alt. 15, greater diam. 21, lesser 171 mill.

 color, but the upper one is sometimes faint, the surface then usually
