Representatives of the third division of Caranx, e Les Ca- 

 rangues ' (Cuv.), also exist in the seas of Australia. The 

 Caranx Lessonii (Cuv. and Val. ix. p. ] 13) was brought from 

 New Holland by MM. Lesson and Garnot, and is considered 

 by Cuvier to be the gundi-parah of Russell, p. 144. The 

 Caranx speciosus (Cuv. and Val. ix. p. 130), which inhabits the 

 Red Sea, the Indian Ocean, and the Polynesian Archipelago, 

 was brought by Bougainville (le fils) from New Holland. 

 The Scomber platinoides of Solander, of which the only me- 

 morial is the following brief notice, is probably a member of 

 this division.
