brown round the umbilicus. I am indebted for it to Mr. Water- 

 house, the curator of the South Australian Museum. {Brazier.) 



H. SUBLORIOLIANA Pilsbry. PI. 58, figs. 10, 11, 12. 



Shell depressed, narrowly umbilicated, rather thin, light yellowish 

 with a chestnut band at the suture, another just above the periphery, 

 the interior of the umbilicus also chestnut colored ; surface striatu- 

 late, not granulate ; outer lip simple, suddenly dilated at columella 

 into a small triangle partially covering the umbilicus. 



The contour is considerably like H. cassandra, but the spire more 

 conoidal ; whorls 5, moderately convex, the last rounded at the 

 periphery, a trifle descending in front. Aperture oblique, rounded 

 lunar, delicate flesh-colored within, showing the bands ; peristome 

 simple, white, the columellar triangular dilation flesh-colored. The 

 surface is delicately obliquely striatulate but not at all granulated. 



Alt. 14, greater diam. 23?, lesser 20 mill.; width of umbilicus 1 

 mill.

H. lorioliana Cox, Monogr. Austr. L. Sh., p. 52, t. 3, f. 4a, 4b, not 

 of Crosse ! 



Far more depressed than the true H. lorioliana Crosse, with speci- 

 mens of which I have compared it. 



H. CASSANDRA Pfeifler. PI. 58, figs. 7, 8, 9. 



Shell depressed, moderately umbilicated, the spire low ; whitish, 

 with two pale brown bands above ; surface delicately striatulate and 

 densely microscopically granulate all over, save the polished apical 

 whorl. Columella triangularly dilated half over the umbilicus. 



The shell is depressed, spire broadly convex and low; rather 

 thin ; nearly white beneath, pale isabelline above, with a pale brown 

 band at suture and another above periphery. Whorls 5, the inner 

 one polished, convex; suture at first impressed, then becoming 

 shallower. Last whorl depressed, rounded at the periphery, slightly 

 descending in front ; aperture round-lunar, white within ; peristome 

 simple, the columella suddenly expanded, half covering the um- 

 bilicus. 



Alt. 13, greater diam. 23, lesser 19 J mill.; width of umbilicus 2 

 mill.
