EDIBLE FISHES OE NEW SOUTH WALES. 31 



frequents localities liavins a saudj bottom at a moderate depth, and, tliere- 

 fore, but rarely comes into contact with the Snapper fislier, no remedy is 

 likely to be found until our magnificent stretches of outside sandy grounds 

 are properly surveyed, and scientifically fished by powerful steam trawlers. 



This species is a native of the southern coast of Australia, tlie first 

 example described having been obtained on the coast of Soutli Australia, 

 and extends its range northwards along our own seaboard at least as far 

 as Cape Hawke, beyond which I have been unable to trace it. Macleay 

 records it from Tasmania, but Johnston in his more recently published 

 Catalogue of the fishes of that colony makes no mention of it ; it is, however, 

 certain to occur in Tasmaniau seas. A closely allied but very distinct 

 species — R. recurvirostris, Eichardson — characterised by an increased number 

 of dorsal spines, and a broad curved black band extending from the origin of 

 the dorsal to the end of the anal, occurs there and on the Victorian coast, 

 but has not as yet been recorded from New South AYales waters, whence, 

 however, a third easily distinguished species, recently described as H. 

 elevatus. Ems. & Ogl., but which is probably the Japanese R. ti/pus, Schleg., 

 has been taken on two occasions by the trawl in from thirty five to seventy 

 fathoms between Botany and Port Hacking Heads ; this species may be 

 easily recognised by the greatly increased number of dorsal and anal rays, 

 and especially by the great comparative height of the body, which is 

 contained only two and a third times in the total length.
