viz. Crinia, Hylodes^ kc, prove that too great an importance has 

 been attached to the modilications of this organ, and in most 

 cases I must refuse to admit them as generic characters." It 

 may be that it is attaching undue weight to the character 

 "tympanum concealed" to rank it as of generic importance in 

 Heleioporus. On the other hand two species of the genus are 

 already known, and the character in question is allowed due 

 weight in discriminating Cri/ptotis and Phanerotis; and therefore 

 as the definition of the genus, as it at present stands, excludes the 

 frog now under consideration the best course open to me seems 

 to be to propose a new genus for it. 



Reference has already been made to the fact that Heleiojjorus 

 albopunctatus, Gr., has by two authorities been recorded as a 

 Sydney frog, namely in the second edition of the British Museum 

 Catalogue, and by Keferstein in his well-known paper — records 

 the correctness of which I believe to be open to doubt on the 

 following grounds. Mr. Krefft knew this frog well enough ; 

 nevertheless in his three lists of Australian frogs published 

 during the years 1867-71 he gives as the habitat of H. albopunc- 

 tatus King George's Sound ; or Western Australia (particularly 

 King George's Sound), Murray River, North Australia (?) ; or 

 West and North Australia"^ : never does he include it among the 

 species known to occur in New South Wales. Nor have local col- 

 lectors of a later date been any more successful in finding it in this 

 colony. It is very remarkable therefore that the single specimen 

 from Sydney in the British Museum should stand recorded in tlie 

 Catalogue as presented by Mr. Krefft ; and that Keferstein's five 

 su])posed Sydney specimens should have been part of a collection 

 supplied either by Mr. Krefft himself or by the late Dr Schuette 

 who in his turn probably obtained all, or all but the Sydney 

 specimens forwarded by him, from Mr. Krefft. Moreover the 

 last of Mr. Krefft's papers appeared in " The Industrial Progress 



* Evidently Mr. Krefft is only quoting most of these localities on the 

 authority of Dr. Giinther [B. M, Catalogue (first edition) and Ann. Mag. 

 Nat. Hist. July, 1867 (3), xx. p. 54] ; not so, however, in regard to King 

 Oeorge's Sound.
