62~ THE VICTORIAN NATURALIST. 



ranges appear to be too dry and devoid of vegetation — except 

 eucalyptus saplings — to harbour land forms. After thoroughly 

 examining this radius, however, I started further afield, and was 

 rewarded with much better success. I have now extended my 

 radius to sixteen miles, but as this embraces a very large tract of 

 country I do not pretend to have made anything like a thorough 

 examination of it yet, but hope to do so by degrees. My best 

 hunting-grounds at present are the granite ranges of Hafcourt 

 and Mount Alexander, about eight miles to the north ; Expedi- 

 tion Pass reservoir, four miles to the east, on the junction of the 

 granite and silurian slate and sandstone ; Mount Franklin and 

 the adjacent basaltic country, sixteen miles to the south ; and the 

 neighbourhood of Yandoit, twelve miles to the south-west, also 

 basaltic. My list now comprises ten species, viz. : — Two Helices, 

 one Succinea, two Limn^ea, three Bulini, one Ancylus, and one 

 Unio. They have nearly all been identified for me by Dr. Cox 

 and Chas. Hedley, Esq., of Sydney, to both of whom I am 

 greatly indebted for the very kind assistance they have given me 

 in my endeavours to find out something about this branch of our 

 local fauna. I will now proceed to make a few remarks on the 

 various species. 



Charopa tamarensis, Petterd (described in Petterd's "Mono- 

 graph of Tasmanian Land Shells," p. 30), from Launceston, 

 Tasmania, and not hitherto known to exist elsewhere. Mr. 

 Hedley writes that both he and Mr. Brazier compared my 

 specimens with authentic examples received from Petterd, and 

 there can be no doubt about the identification. I found this 

 very minute species in the crater of Mount Franklin, but have 

 not taken it nearer to Castlemaine yet. Mount Franklin, be it 

 noted, is north of the Dividing Range. Query : How did a 

 species hitherto recorded from Tasmania only get there ? 



Charopa retepora, Cox. — Dr. Cox thought at first this was 

 an undescribed species, but eventually identified it as one he had 

 named from specimens received from Flinders Range, South 

 Australia. It is a pretty little shell, of a light horn colour when 

 the animal — which is black — is extracted ; and the whorls, when 

 examined under the lens, are seen to be beautifully ribbed. It is 

 not uncommon in the ranges nortli and east of the town, and I 

 also took it in the crater of Mount Franklin, in company with 

 H. tamarensis. It is found under logs and stones, in gullies, and 

 also on sides and summits of hills. The specimens vary in that 

 some are umbilicated and others not. 



Succinea australis, Ferussac. — I took two single specimens 

 of this shell under an old log quite near the town. Later on I 

 found a considerable number under the bark of eucalyptus trees 

 in the Expedition Pass Reservoir reserve, and since then 1 have 

 found it to be very common at Harcourt, under the bark of trees.
