spire, whorls 5 to 8, obliciue, last whorl iuflatctl, aperture 

 widely ovate ; outer lip extremely thin, fragile ; inner lip some- 

 what expanded, columella fold inconspicuous ; columella 

 white, scarcely twisted. Long. 25. Lat. 12. Apert. 15 mill. 

 But tliis is a large size. 



Habitat. — Everywhere in South Tasmania about Hobart. 

 This shell is very like Limiuva starjnalis, Linn, but the spire is 

 not so attenuated, the aperture not nearly so expanded, the 

 columella fold is inconspicuous, the columella white, and the 

 shell much smaller and thinner. It also comes near some 

 American species.

 obliqua, pallide-carnea, spira brevi, anfractibus 4> duabiis apicali- 

 hus parvis, rotuwlis, pemdtimo tnajusculo, ultimo inflato ; post

 obsoleta. 



L. shell ventricose, subumbilicata, oblique, horny, spire 

 short, whorls foui*, the two apicial ones small, 

 rounded, the penultimate somewhat larger, the last 

 inflated ; concave behind, the columellar aperture pyriform, 

 obliquely expanded in front, outer lip thin, inner lip 

 expanded, columellar plait almost obsolete. Long. 11. Lat. 

 &. Aperture 9 mill. 



Habitat, very common about waterworks near Hobarton. 

 Closely allied to preceding, but the spire is more conspicuous 

 and the shell oblique, more solid, and altogether larger,
