204 NOTES ON A COLLECTION OF FISHES FROM QUEENSLAND, 



the preparation of a very favourite condiment. The air-bladder of 

 this species will probably be found, like that of P. jdebejus and 

 indicus, to give a profitable yield of isinglass. It is said to attain a 

 length of 4 feet. 



Sci^enid^e. 

 18. corvina argentea. 11. sp. 



D. 10, 1/29 ; A. 2/7. L. lat. 52. 



Height of body, about 3 J times in the total length ; length of 

 head, about four times in the same ; snout obtuse, convex, rounded, 

 the jaws equal, the maxillary extending to behind the middle of 

 the eye, which is large and about its own diameter distant from 

 the snout. An outer series of strong, curved, sharp teeth in the 

 upper jaw. Prreoperculum very slightly and distantly serrated ; 

 suprascapula crenulated ; coracoid entire. The first dorsal spine 

 is minute, the second and third very high, the other spines 

 becoming gradually lower to the tenth, which is very small ; the 

 second anal spine is very large, nearly as long as the first ray ; the 

 tail is rather pointed. Colour, silvery all over, the extreme edge 

 of the spinous dorsal fin is black. 



Lower Burdekin, in salt water. 



This is also an abundant and valuable fish, and is probably like 

 its congeners in the Indian seas, a yielder of isinglass.

The height of the body is contained 3 J times in the total length. 

 Body very compressed, the back from the dorsal fin to the snout 

 forming a very sharp, narrow ridge. Mouth oblique, the maxil- 

 lary broad and triangular at its extremity, fitting into an emar- 

 gination of the prseorbital, and extending to below the anterior
