Por the purpose of serving as a starting point, and to determine the 

 identity of this the first mentioned of Australian Succinea, I have 

 copied. Pfeiffer's description, taking the measurements from my own 

 specimens. Perhaps l( acutely" had better be substituted for 

 "acuminately;" I cannot count more than 3 whorls, the number 

 represented in Ferussac's figure. 



When Perussac named and described this species, he gave as its 

 habitat " Australian Isles." Quoy and Gaimard afterwards found 

 in Tasmania a Succinea, which the)' also referred to S. Australis, and 

 figured and described it. Of course, neither their descriptions nor 

 figures agree perfectly. Pfeiffer, many years afterwards, having 

 previously in 1848 pointed out the discrepancy between the figures, 

 in 1 8 - j 9 Jlon. Ilel. Viv., Vol. IV., p. 812 gives an original 

 description of S. Australis from Tasmanian specimens, with which 

 certain of those in my collection agree. It may be mentioned here, 

 in case it should be supposed that New Caledonia is included in the 

 range of this species, that in the " Faun. Conch , Sfe., de la Nouvelle 

 Caledonia,'''' by M. Granics, the figure given from a New Caledonian 

 specimen is that of another species, as one glance at the left lip will 

 show, while the description is Pfeiffer's, verbatim, from Tasmanian 

 specimens. 



In Menke's specimen, " Molluscorum JVovce Hollandice" he records, 

 p. 6, the existence of Succinct' amphibia, of Drap., as occurring 

 under the bark of Eucalypti, in the district of Hay, W. Australia, 

 and S oblong a, Drap., in the fissures of calcareous rocks, not far from 

 the sea, near Perth, Western Australia. The first of these is by 

 Pfeiffer looked on as a synonj-rn of S. putris, Lin., and like the 

 latter is believed to be confined to Europe.
