CLASSIFICATION OF FISHES, ETC. 



very small; the first ray serrated; the rest nearly 

 obsolete. * 



K. arginosus. Cuv. {Jig. 71.) 



3. SuBFAM. TRACHIURIN^. 



Ventral fins wanting^ or merely rudimentary ; finlets 

 none ; body narrow_, linear ; jaws lengthened, the under 

 much the longest, and having the chin pointed ; teeth, 

 in general, large, remote, unequal, and acute. 



TRicHirBus Vand. (^Jig.'72a.) Caudal fin none; the tail 

 being gradually narrowed and attenuated to a point ; 

 anal fin none ; dorsal fin commencing on the nape, 

 and extending nearly the whole length of the body, 

 haumela Sch. Cuv. pi. 224. (lepturus Auct.') 



^rrs-rr-r' 



LEPiDOPrs Gouan. Caudal fin small and forked {^jig. 

 72. ?/.) ; pectoral falcated in the middle (c) ; head, 

 body, and dorsal fi.n as in Trichiurus ; but there is a 

 short and narrow anal fin. 



L. ensiformis Vandeli. Cuv. pi. 223. f 



Ammodytes Linn. {fig. 73.) Pectoral fin simply pointed; 

 anal fin long and fully developed ; caudal forked ; 

 lateral Une close to the dorsal ; teeth small. 

 Siculus. Zool. 111. i. series 1. pi. 63. 



* This singular type appears to represent, in this sub-family, the Acan- 

 thurinw and the genus Pricdon : if this view is correct, its analogy to all 

 the serrated rayed fishes, as Trigla, Batistes, Siluridce, kc, becomes mani- 

 fest. 



t M. Cuvier lias changed the specific names of these two fishes without any 

 necessity. I have restored Schneider's to one, and Vandelli's to the other ; 

 the references which foUow are merely for the figures. It is quite obvious 

 that Lepidopus is intimately allied to Ammodytes^ though placed by Cuvier, 

 without any assigned reason, in a diflFerent order.
