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

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

 CaraucV Lessonii (Cuv. and Val. ix. p. 1 13) was brought from 

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

 by Cuvier to be the (/undi-parah of Russell, p. 144. The 

 Caranx speciosus {Cny.and\a.\.ix. -p. I oO), 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. 



" Saepe pedalis, totus argenteus, nitidissimus, dorsum parum cae- 

 rulescens. Iris argentea, pupilla nigra. Macula nigra sublunata 

 postice in angulo laminae operculi posticae. Pinnae parum lutescunt, 

 praecipue pinna analis. Habitat Tolaga." (Pisces Austr.) 



A pencil reference to Sc. hippos, with a mark of doubt, is 

 appended to the MSS. The Sc. hippos ? of Forster, of which 

 a figure exists in the Banksian Library, and a description in 

 Schneider (p. 28), was taken at Otaheite, and not in New 

 Zealand, as stated in the ^ Histoire des Poissons,' where it is 

 named Caranx for steri.
