On Two New Species of Land Shells,

Plate 12, Figs. 2. 3. 5. 



The following new species were placed in my hands for 

 description by Dr. James C. Cox, F.L.S. The first is from 

 Tasmania. A medium sized form, very closely allied to Helix 

 atramentaria, of the Dandenong Ranges, Victoria. In color, 

 enamel, and the form of the embryo it is very similar, but it 

 is smaller, more sloping, less discoid, and of fewer whorls. I 

 have figured both species on the accompanying plate, so that the 

 differences may be seen at a glance. It is very desirable that 

 the animal should be studied, as the highl}^ enamelled exterior 

 surface, which is also smooth, renders it probable that the 

 Victorian shell is also a Helicarion, with a caudal gland. The 

 membranaceous edge makes it very probable. It should be 

 observed that without a knowledge of the animals Albers * places 

 our Australian Vitrinoe as Helicarion. This genus was established 

 by Ferussac in 1821, for the Australian H. Fyeycineti f G. B 

 Sowerby subsequently united it to Vitrina. Latreille, Blainville. 

 and Sander Rang regarded it only as a sub-genus. Menke, in 

 1830, and Beck, in 1837, J revived the genus, which is thus 

 defined by Adams : — " Mantle with two free lobes in front on the
