24-6 CLASSIFICATION OF FISHES, ETC. 



subfalcated ; caudal forked ; scales small,, distinct ; 

 ventral moderate, pointed. 



S. georgianus. Cuv. pi. 245. 



Seriola. Body oblong ; dorsal fins two, distinct, the 

 first spinous, and having an incumbent spine, 

 pointing forwards at its base ; pectoral fins small, 

 pointed, but not falcated ; scales of the body small, 

 but well-defined and obvious ; two spines close to 

 the base of the anal fin ; tail not carinated. 



Nomeus* C. General shape and character of Naucrates, 

 but the dorsal spines are united into a distinct fin 

 by being connected with a membrane ; tail not cari- 

 nated ; ventral fins very large, considerably exceeding 

 the pectorals in the typical species ; pectorals, and 

 lobes of the caudal fin, roimdecL 



Peronii. Griff. Cuv.pl. 26. 1. nigro-fasciatus. Riipp. i. 

 argyromelas, Cuv. pi. 269. pi. 24. fig. 2. 



Temnodon Cuv. First dorsal fin much smaller and 

 lower than the second ; mouth large, lower jaw 

 longest, both armed with detached acute teeth in 

 each jaw in the front row, and others much smaller 

 behind ; velvet-like teeth are also on the tongue, 

 palate, and vomer ; second dorsal and anal covered with 

 small scales : representing Scorpis. 

 saltator. Cuv. pi. 260. 



Seriola Cuv. Body oblong, fusiform; first dorsal fin 

 small, low, with an incumbent spine at its base, point- 

 ing forward ; second dorsal long ; the posterior rays 

 short ; the rays sometimes divided into finlets ; pec- 

 toral and ventral fins about equal. 



S. DumeriliL Cuv. pi. 258. 



Psenes Cuv. Body broad, oval ; snout very short, ob- 

 tuse, nearly truncate, having the general form and 

 proportions of Trachinotus ; first dorsal fin as high 

 as the second, and without an anterior spine directed 



* The discovery of the first species in our list connects Seriola and Cen- 

 tronotus in the most perfect manner by the union of Naucrates with No» 

 metis.
