INDEX TO THE LAND SHELLS OF VICTORIA. 
After Panda and Paryphanta, this is the largest Victorian snail. 
When deprived of its characteristic bristly epidermis, it seems 
transformed into another species. It is obvious that this is what 
Professor Tate doubtfully recorded* from Fernshaw as II. mansueta, 
Pfr. The latter is a Queensland shell bearing a general resemblance 
to C. victorice in size, form, and colour. But C. mansueta may be 
distinguished in all stages of growth by the broader umbilicus and 
sparser bristles. Professor Tate’s record (op. cit.) of H . brevipUa, 
Pfr., from Melbourne is evidently again a misquotation for C. vic- 
tories. During the preparation of the Revised Census of the Terres- 
trial Mollusca of Tasmania , Mr. W. F. Petterd was not quite satisfied 
of the identity of C. brunonia with C. victorice. In the last letter we 
received from him, he had decided that they were the same. This 
decision is here adopted. The species seems to be common and 
widely distributed. We have received specimens from the fol- 
lowing places : — Western Port (type locality, Masters and Petterd), 
Victorian Alps (French), Jan Juc (Kershaw), Forrest (Steel), Lome 
(Pritchard), Loutit Bay (Kershaw), and Cape Otway (Petterd). 
Beyond Victoria it is only known from King Island, and from Mt. 
Kosciusko.

This species is generally distributed throughout the State. It 
was first recorded from Victoria by Mr. W. F. Petterd, who remarked 
that “ specimens from the Dandenong Range, Victoria, are identical 
with those from the northern portion of this island ”f, i.e., Tasmania. 
Professor Tate appears to have considered, on the contrary, that 
mainland shells should be specifically distinguished from the Tas- 
manian, and proposed to name the Victorian form, which he recorded 
from Sale, Cape Otway, and Fernshaw, as Helix exoptata, but he 
never published a formal description or noted differential characters. 
The size principally distinguished R. ruga from its northern 
relations, and it may prove a dwarf of a widespread species which, 
in different parts of Australia, has received different names. We
