320 ANNUAL RECOED OF SCIENCE AND INDUSTRY. 



flesh is said to be excellent and rather red, on which account 

 it is called the Burnett salmon. It is quite restricted in its 

 habitat, having only been met with in the Burnett and the 

 Condamine Rivers. The Osteoglossum leichardti reaches a 

 weight of twenty-five pounds. The fish is very handsome, 

 and is taken with the hook. The Neoceratodus hlancTiardi is 

 something like the Ceratodus, but differs in the structure of 

 the teeth. It is found in the River Fitzrov, and attains a 

 weight of from forty to ninety pounds. 



The rivers in which this fish is found become almost dry at 

 certain seasons of the year, and it is still a problem what be- 

 comes of them, although it is suggested by some that they 

 bury in the mud, and remain there until the return of water.

POEY's catalogue of CUBAN FISHES. 



Professor Felipe Poey, the veteran Cuban ichthyologist, 

 has recently published a catalogue of the species of that isl- 

 and, in which he enumerates seven hundred and thirty spe- 

 cies. Of these, seventy-eight are considered somewhat doubt- 

 ful, leaving six hundred and fifty-two. Of these, sixty-four 

 will probably prove to be undescribed, but the determination 

 of this will depend upon further researches and compari- 

 sons. 



HABITS OF THE SALMON. 



Mr. Henry Lee has lately published some of his observa- 

 tions on the salmon in the Brighton Aquarium in the London 

 Field^ which throw much light upon some of the vexed ques- 

 tions in regard to the natural history of this noble fish. He 

 states that in April, 1873, nine salmon smolts, taken in the 

 Usk River on their way to the sea, were placed in the aqua- 

 rium. These were kept in tanks, some of them in fresh wa- 

 ter, to which salt was afterward added gradually ; the others 

 were placed directly in the salt water, the latter apparently 

 sustainiufv the chano-e better than the others. Most of these 

 fish died after a short time ; two, however, remained, which 

 Avere fed on shrimps and minced fish, and grew so fast that 

 their increase was appreciable day by day. At the end of 

 twelve months after their receipt, or, in April, 1874, only one 

 survived, and this fish for a time ceased to grow, and was
