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.) 



New Britian.

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 4J, 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 17* mill.

The expanded columella is pink ; the brown bands are generally

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