674 AUSTRALIAN BATRACHIA, 



(h) The Batrachia of West Australia. 



The number >jf species assigned to West Australia at different 

 times has been : — 



1841. — One species (Dumeril and Bibron, op. cit.) 



1841. — Six sjiecies — nominally seven, H. bioculata and H. 

 adelaidensis being treated as distinct — (Mr. J. E. Gray, op. cit.). 



1858. — Nine species — nominally ten, Mt/obatrachus and Chely- 

 flobatrachtis being treated as distinct — (Dr. Giinther, op. cit.). 



1867. — Five additional species either from Mr. Duboulay's 

 collection or forwarded by Mr. Krefft (Dr. Giinther, Ann. Mag. 

 Nat. Hist. (3), XX., p. 53). Total, fourteen species. 



1882. — Fourteen species (Mr. Boulenger, op. cit.). That is to 

 say, without additional material, Mr. Boulenger's revised list of 

 species practically differs from Dr. Giinther's only by the recogni- 

 tion of Jfjjobntrachvs and C hehjdobatrachus as identical, and the 

 substitution of Pseudnphryne gnentheri, n.sp., for P. bibronii. 



Of these fourteen species I have seen representatives of nine, 

 together with examples of six others not previously recorded, one of 

 whichdoes not quite satisfactorily agree with the description of any 

 known species For the data on which my observations are based 

 I am largely indebted to Messrs. E. P. Richards, H. Richards, 

 R. Helms, and especially to Mr. A. M. Lea, who have most kindly 

 taken some trouble to collect and forward specimens to me. By 

 the courtesy of Mr. Masters, Curator of the Macleay Museum, I 

 have also been able to examine the specimens collected by Mr. 

 Froggatt in the neighbourhood of King's Sound in 1887, part of 

 the general collections referred to by Sir William Macleay 

 (P.L.S.N.S.W. [2], ii. p. 1017). And by the kindness of Professor 

 Baldwin Spencer, of Melbourne, I have been able to see the 

 specimens brought back by the Calvert Expedition, which were 

 collected by Mr. G. A. Keartland while stationed at the junction 

 of Fitzroy River and Margaret Creek, about 150 miles from 

 Derby. 



The number of species at present assignable to West Australia 

 is twenty; but one or two of these need confirmation.
