greater approximation to the truth than does Dobson's treat- 

 ment of it in the ' Catalogue,' where but a single species is 

 recognized. 



As Tomes stated, quite a number of species are distin- 

 guishable by the characters of their skulls, although it is not 

 at present possible to define them all completely. The 

 earliest name, timorietisls, Geoff., should, I think, be dropped 

 for the present, as it is impossible to identify it with certainty 

 among the Australian species, and it may yet turn up in 

 Timor. Prof. Trouessart tells me the forearm of the type 

 measures 42 mm., a very undi.stinctive length. For the large 

 species called titnoriensis by Tomes I should use major, 

 Peters, 1861 *, of which the type is the British Museum 

 specimen 44. 7. 9. 20. The other W.-Australian species is 

 geoffroyi. Leach (syn. aust rails, Pet.), which ranges over a 

 large part of the central area of the continent. In the north 

 and east we have gouldi\ Tomes, and in the south-east and 

 Tasmania unicAur, Tomes. In N. Australia also tliere is the 

 peculiar little iV. walkeri, Thos., with quite small ears and 

 bullfo, and in New Guinea N. microtis, Thos. Gray' sp'icificus 

 still remains to be identified; it has a skull very like that of 

 unicohr, but the forearm is shorter. It will, perhaps, yet 

 turn up in one of the " Islands of the Pacific." 



XLVII. — Descriptions of Three new Ftshes from South 

 Cameroon. By G. A. BOULENGER, F.R.S. 



(Published by permission of the Trustees of the British Museum.) 



Examples of three new species were contained in collections 

 of fresli water fishes recently made by Mr. G. L. Bates in 

 the Ja River, an affluent of the Sanga (C'ongo Basin), and 

 are here described. The types are preserved in the Britisli 

 Museum.
