AUSTRALIAN LAND SHELLS. 85 



Habitat. Poit Western, Victoria. Quoy et Gaimard. 

 The preceding is taken, from Quoy, who remarks that the animal is 

 black, large, with an elongate neck, and contractile into the shell. 



205. Vitrina Strangei. PJr. Plate XIV. Fig. 9, 9 a. large 

 variety. Plate XIV. Fig. 3, 3 a. small variety. 



PJr., Pro. Zool. Soc, 1849, p. 132. 

 Peeve, Cone. Icon. sp. 48. 



Shell depressly semi-globose, thin, smooth, transparent, very faintly 

 arcuately striated, more conspicuously at the suture, and sometimes, 

 under the lens, shewing indications of spiral impressed lines, golden, 

 yellowish, greenish, or pale hyalme; spire small, slightly prominent, 

 suture impressed, slightly bordered; whorls 3, slightly convex, 

 rapidly increasing, last depressed above, rounded outwardly, and 

 more convex below ; aperture oblique, large, lunate, rounded ; 

 peristome simple, rather blunt, margins approximating, right dilated 

 forwards, columella receding, much curved, with a narrow membra- 

 nacious margin. 



Diameter, greatest 065 ; least 0'45 ; height G"25 ; aperture 0"40 long ; - 37 

 wide, of an inch. 



Habitat. Cook's River. Lane Cove. Mulgoa. Dural. Clarence 

 and Pichmond Rivers, N. 8. W. Brisbane. Fitzroy River, Queens- 

 land. Cox. 



A shell so widely distributed might be expected to present many 

 variations, yet it does not, excepting those of mere size, colour, 

 and degree of transparency ; almost universally, however, it is a 

 beautifully bright, clear, transparent shell. 



206. Vitrina hyalina. Pfr. Plate XIV. Fig. 7, 7 a. M.C. 

 PJr., Pro. Zool, Soc, 1854, p.' 296. 



Shell clepressly-globose, very thin, smooth, pellucid, greenish hyaline ; 

 spire slightly elevated, slightly obtuse; whorls, nearly 4, slightly 

 convex, last smooth towards the suture, which is margined, distantly 

 radiately striated, *rounded at the base, rather wide ; aperture 

 diagonal, lunately rounded ; peristome simple, right margin rather 

 dilated in front, columella very much arched. 



Diameter, greatest 27 ; least 0'21 ; height 0-14 of an inch. 



Habitat. Moreton Bay. Strange. 



The smallest recorded Australian species, found, I believe, on trees. 

 Specimens of a small leaf-inhabiting Vitrina from Queensland 

 and the Richmond River, and also Elizabeth Bay in the vicinity of 

 Sydney, in my collection, I refer, but not with certainty, to this 

 species. The whorls in the largest are not more than 3 ; the spire 

 is not elevated, and the columellar margin is membranous. I may 

 add that they are not the young of other species. 



207. Vitrina virens. Pfr. Plate XIV. Fig. 5, 5 a. M.C. 

 Pfr., Pro. Zool. Soc, 1848, p. 108. 



Reeve, Cone. Icon. sp. 14. 



Shell depressed, somewhat broadly ear-shaped, or roundly elliptical,
