86 FISHES. 



Blocli, 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- 

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



Lates, Cuv., 



Tlie 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 antieuts by the name of Lotus or Lates. 

 Other species are found in the rivers of Indiaf . 



Centropomus, Lacep. 



The Centropomes have the preoperculum dentated, but the operculum 

 obtuse and unarmed. Only one species is knowii]};. 



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, CllV.y 



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 [j. 



AspRo, Cuv., 

 Plave the body elongated; the two dorsals separate; ventrals broad; 



* It is also the Perca MitcMlli, New York Trans, v. I, 413. Add, Perca elongata, 

 Geoff. Eg. pi. xix, 1; — Labr. waigiensis, Less, and Garn., Cuv. and Val. II, 33; — 

 Labr. japonicus, Cuv. II, 85. 



t 'Ihe Piche naire of Pondicherry, or Cockvp of the English at Calcutta (Latis

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

 its characters, such as tlie Labrax lupus, tlie lutes, &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. 



II Gram, orienlalis, Bl., Cuv. and Val. II, pi. xxvii. La Sci&ne rayee, Lacep. IV, 323 ;
