86 FISHES. 



Bloch, Schn. pi. 20, (the Rock-fish), with longitudinal blackish 

 stripes*. 



We might also separate from Labrax a species of the United 

 States, whose scales extend to the maxillary bone — Labrax mucro- 

 nattis, Cuv. and Val. II, xii. The 



Lates, Cup., 



The Varioles, hardly differ from the Perches, except in having deep notches 

 and even a small spine at the angle of the preoperculum, and also 

 deeper notches in the sub-orbital and humeral bones. 



Lates niloticus, Cuv. ; Perca nilotica, L. ; Keschr of the Arabs, 

 Geoff. Egyp. Poiss. pi. ix, f. 1. A very large and excellent fish of 

 a silver colour, known to the antients by the name of Lotus or Lates. 

 Other species are found in the rivers of Indiay. 



Centropomus, Lacep. 



The Centropomes have the preoperculum dentated, but the operculum 

 obtuse and unarmed. Only one species is known J. 



Centrop. undecimalis, Cuv. ; Scicena undecimalis, Bloch, 305 ; 

 Cuv. and Val. II, xiv. A large and excellent fish, known through- 

 out the hot parts of America by the name of Pike, whose muzzle, in 

 fact, is depressed like that of our true Pike ; but its teeth are small 

 and crowded, and all its remaining characters are those of Perches 

 with two dorsal fins; it is of a silver colour tinged with greenish; a 

 blackish lateral line §. 



"Grammistes, Cuv., 



Have the preoperculum and operculum armed with spines, but without 

 notches ; the dorsals approximated ; scales small, and as if buried in the 

 epidermis ; no sensible spine to the anal fin. 



The species are small, with longitudinal white streaks on a black- 

 ish ground. They inhabit the Indian Ocean ||. 



Aspro, Cuv.,

I Lacep. in his genus Centropomus, comprehends several Fishes which have not 

 its characters, such as the Labrax lupus, the kites, &c 



§ Bl. pi. 305, has improperly given it a red tinge; the Sphyrene orvert, Lacep. V, 

 pi. iv, f. 2, is nothing else than a bad figure of this fish; it is also the Camuri of 

 Marcgrave.
