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 Eleotris, known here as the " Gudgeon," is as 

 yet recorded, though the genus exists in Australia, New 

 Zealand, and South America ; of the Oalaxidce, 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 

 Eiver, collected by Mr. Masters ; the " Common Eel," Anguilla 

 australis, and the well known " Fresh-water Herring," JBroto- 

 troctes 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 



27 Mammals 

 162 Birds 



6 Lizards 



3 Snakes 



7 Frogs, and ^ 



4 Fresh-water Fishes. 



Together 209 Yertebrata 



about thirty-seven of which may be considered peculiar to 

 Tasmania. 



The Invertebrata were collected to the number of more than 

 one thousand species, that is to say, of the class Insecta, nine 

 hundred and fifty species, and ninety-eight of the class 

 MoUusca ; twenty-one of the latter are Land-shells, and nearly 

 all peculiar to Tasmania. The insects appear, with few excep- 

 tions, to be identical with Australian species. 



The following is a list of the Invertebrata : —
