Genus I.— CARANX.

 Trachurus, Cuv. & Val. Hist. Nat. Poise, ix. p. 6, 1833. 

 Carangichthys, Bleek. Celebes, iii. p. 760 



Branchiostegals seven : pseudobrancliijie present. Body oblono^, or elevated, 

 or subcylindrical, more or less compressed. Cleft of moutli moderate. Eyes 

 lateral, with or without adipose lids. Dentition feeble, more or less complete. 

 Two dorsal fins, the first continuous, with about eight feeble spines which are 

 sometimes rudimentary, and having in front of its origin a recumbent spine 

 directed forwards : the second dorsal more developed than the first, and 

 similar to the anal ; the posterior rays of both these fins sometimes wholly 

 or partially detached: two preanal spines, which are sometimes rudimentary, 

 separated by an interspace from the anal fin. Scales minute. Lateral line 

 with an anterior curved and a posterior straight portion, the latter covered 

 with large plate-like scales, which are usually keeled, and sometimes spinate ; 

 these are rarely continued on to the anterior curved portion. Airbladder 

 bifurcated posteriorly. Pyloric appendages in large numbers. 



Geographical disfrihufion.— Almost all temperate and tropical seas, more 

 especially abundant in the latter. 



This is a very large and complex genus, embracing species with little or no 

 external resemblance to one another, and might conveniently bo subdivided 

 into two or more genera.
