Inhabits New Holland. Dr, Leach. And is a fresh-water 

 shell. Schroeter. 



Shell an inch and a quarter long, and three-quarters of an inch 

 broad, of a somewhat glossy waxy white colour, with rather 

 broad more or less undulated dark chestnut longitudinal 

 stripes, of which some are interrupted ; it has six or seven 

 rather ventricose whirls, of which the body-whirl is thrice 

 as large as the next, and the lip by the pillar is reflected so 

 as almost entirely to conceal a small obsolete umbilicus. 

 My friend Dr. Leach favoured me with a specimen of this 

 shell from New Holland, under the name of H.striatus, and 

 it is very nearly allied to Bulla Zebra, which belongs to the 

 same natural family ; but my present attempt is only to de- 

 fine the species, and 1 have therefore left that shell in the 

 Genus to which it has been referred by other authors. 



FLUViATiLis. 162. Shell sub-tiiiTeted, very smooth, 

 and brown with darker spots ; aperture nearly 

 round, and the throat whitish.

 ture is roundish, and the inside bluish white.
