The Vertebrata of Tasmania. 41 



The Tasmanian frogs are also few in number. The Hj/lce, or 

 " Tree Erogs," represent three species, viz., the common " Grolden 

 Tree Frog," Hyla aurea; "Ewing's Tree Frog," Hyla ewingii ; 

 and a kind, which I consider to be identical with Hyla vcrreauxii, 

 all of which are common on the mainland of Australia. Of 

 Swamp-Progs, we find the widely distributed Limnodynastes 

 tasmaniensis, a Pseudophryne discovered by Mr. Masters and 

 probably new, Pteroplirynus tasmaniensis, and P. lcevis,the two latter 

 much infected by thelarvseof a small fly of the Grenus Batracliyomya, 

 (Macleay,) which insects are also found on allied species in 

 Australia. 



These are all the species of frogs known from Tasmania, up to 

 the present time. 



The fishes, such as inhabit fresh water only, are also limited. No 

 PJleotris, known here as the " Gudgeon," is as yet recorded, 

 though the genus exists in Australia, !New Zealand, and South 

 America ; of the Galaxidce, the so called " Black-fish," appears to 

 be most common in the Tasmanian streams ; this is Richardson's 

 Galaxias truttaceus; we also have specimens of the Galaxias 

 attenuatus, from the Ouse River, collected by Mr. Masters ; the 

 " Common Eel," Anguilla australis, and the well known " Fresh- 

 water Herring," Prototroctes marcena. I wish I could have added 

 the Salmon, but at present no authenticated specimens exist in 

 any of our colonial museums. Competent judges state that the 

 Salmon has been duly acclimatized and has been frequently 

 observed in the Derwent, it is therefore much to be regretted, 

 that no specimen has yet been caught, if only to prove beyond 

 doubt the success of one of the greatest experiments of modern 

 times. 



In summing up the whole Yertebrata of the island, leaving out 

 the extinct Dingo, Seals, "Whales, and Marine fish, we find there are 

 26 Mammals 

 162 Birds 



6 Lizards 



3 §nakes 



7 Erogs, and' 



4 Eresh-water Eishes. 



Together 208 Yertebrata 



about thirty-seven of which may be considered as peculiar to 

 Tasmania.
