ICHTHYOLOGICAL NOTES (No. 2J.—0GILBY. 133 



•species may be easily distinguished by the width of the internarial region, which 

 in armatus is less than half the length of the nostril, in granulatus about two 

 thirds of the same. 



RAJID.E. 



I can not agree with Prof. Garman in his identification of the Australian 

 Skates. He places B. a astral is Macleay 27 in the synonymy of B. lemprieri 

 Richardson, 28 and B. scabra Ogilby 20 in that of B. nasuta Solander. 30 In my 

 opinion both B. australis and B. scabra are valid species, while B. lemprieri is 

 hardly separable from B. nasuta. 



ISOSPONDYLI. 



ELOPID^E. 



Some years ago Mr. Tate Regan published "A Revision of the Fishes of 

 the Genus Elops," 31 in which he describes as new two species E. hawaiensis and 

 E. a astral is. From an examination of the specimens in the Queensland and 

 Amateur Fishermen's Museums, I am convinced that the characters on which 

 Regan depends for the separation of the two forms are unstable, and that 

 E. australis should, therefore, be reduced to a synonym of E. hawaiensis. 

 Typical examples of both forms occur in Moreton Bay. 



DOROSOMATID.E. 



DOROSOMA COME (Richardson). 



About 1845 Richardson described the " Perth Herring" of the Swan 

 River as Ghatoessus routes 2 which name Giinther altered to C. erebi 33 in 1868; 

 Castelnau added G. richardsonii 3 * in 1873, in the belief that the " Bony Bream" 

 of the Murray River System differed from the western fish; not content with 

 this Zietz described the Central Australian form from the McDonnell Ranges as 

 G. horni 35 None of these three later names have any standing. True, Russell 

 in 1803 3G published a figure of an Indian species over the Hindustani name 

 ' ' Kome ' ' ; true also that Richardson mistook his West Australian fish for 

 Russell's, but I fail to understand how that vitiates the validity of Richardson's
