AUSTRALIAN LAND SHELLS. 83 



oval, within coloured as without; peristome simple, right margin 

 dilated forwards, anterior regularly, and columella slightly arched. 



Diameter, greatest 0'83 ; least 0*60; height - 35 ; aperture 045 long ; 

 0*45 broad, of an inch. 



Habitat. Island in Macquarie Harbour, Tasmania. Milligan. 



This remarkable, shining, and nearly black Vitrina resembles in 

 a most striking manner very young specimens of Helix Busbyi, of 

 New Zealand, but, like all others of the genus, is imperforate.

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



Peeve, Cone. Icon. sp. 21. 



Shell depressed, very thin, diaphanous, smooth, shining, very faintly 

 plicately striated ; spire minute, not projecting, suture impressed, 

 faintly margined ; whorls 3j, enlarging rapidly, last rather narrow 

 at the base, rather depressed above, less so below ; aperture large, 

 elliptically lunate ; peristome simple. 



Diameter, greatest 65; least 040 ; height 0*25; aperture - 40 long ; 

 - 32 broad, of an inch. 



Habitat. Lane Cove, N. S. W. 



Reeve remarks of this, that it is distinguished chiefly by its narrowly 

 produced transverse form.

 from Peeve. 



Pfr., Pro. Zool. Soc, 1856, p. 326. 

 Peeve, Cone. Icon. sp. 42. 



Shell depressly sub-globular, outline oval, very thin, slightly striated, 

 pellucid, shining, yellowish hyaline ; spire scarcely convex, white ; 

 suture hardly margined ; whorls 4, slightly convex, third perceptibly 

 pellucidly radiate, last rounded ; aperture oblique, lunately sub- 

 circular ; peristome thin, margins converging, somewhat inflected, 

 right strongly arched in front, columella nearly straight, short, 

 thread-like. 



Diameter, greatest 0'53 ; least 0"45 ; height 0-33 of an inch. 



Habitat. Australia. 



Not having seen a specimen of this most globular of Australian 

 Vitrina, I have drawn upon Pfeiffer Hon. DTel. Yiv., Vol. IV., 

 p. 796. Peeve says it is globose, and but little depressed, thin, sub- 

 membraneous, with the apex opaque, milky white. I may observe 

 that this kind of white apex is occasionally met with in other 

 species, and frequently in V. Strangei. 



201. Vitrina Verreauxi. Pfr. Plate XIV. Fig. 14, 14 a. M.C. 

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



Peeve, Cone Icon. sp. 21. 



Shell depressly auriform, thin, diaphanous, slightly shining, smooth, 

 frequently rugosely striated at the suture, faintly elsewhere ; spire 

 nearly flat, suture impressed, narrowly margined ; whorls 3, the last 

 depressed above, produced, rounded at the periphery and below ;
