acanthoptervgians. in 



D. macrophthalmus ; Sp. macrophth.,' V>\. 272. Red, witli very 

 large eyes; much rarer than the preceding, and about half its size. 



We distinguish from the other species of Dentex, by the name of Pen- 

 TAPODA, those whose mouth is less cleft, head more scaly, body less ele- 

 vated, and whose caudal is covered with scales to the end*. 



By that of Lethrinus, we distinguish such as have no scales on the 

 cheek ; most of them, as in Hsmulon, have some red about the angle of 

 the jaws f. All these fishes have a pointed scale between the ventrals, 

 and one above each of them. 



A third tribe is also composed of a single genus, 



Cantharus, Cnv. 



Teeth short and dense as the pile on velvet, or bent and crowded like 

 cards all round the jaws; those of the external row being the strongest; 

 body elevated and thick; muzzle short; jaws not protractile. Two species 

 are found in the Atlantic and Mediterranean. 



Canth. vulgaris ; Spams canth.,!^.; Rond. 120, and Duhara., 

 sect, iv, pi. iv, f. 1. Silver-grey, longitudinally striped with brown; 

 some small rough teeth behind the bent ones. 



Canth. brama; Spams hrama, L. About the same colour; all 

 the teeth bent J. 



In a fourth tribe the teeth are trenchant. It comprises two genera, 



Boops, Cuv. 



Teeth of the external row trenchant, mouth small and not at all pro- 

 tractile. Several species are found in the Mediterranean. 



B. vulgaris; Spams boops, L. ; Rond. 136; La bogue vulgaire. 

 Twenty-four teeth in each jaw, with an oblique, cutting edge ; the 

 body oblong, with longitudinal gold-coloured stripes on a silver 

 ground. 



B.salpa; Sparus salpa, L. ; Bl. 265; La Saupe. More oval; 

 stripes of a more brilliant gold, on a ground of burnished steel; teeth 

 broad and emarginated. 



Oblada, Cuv. 



Differ from Boops in having small crowded teeth behind the incisors, 

 which somewhat approximates this genus to Cantharus. 



Ob. melanums; Spams melanurus, L. ; Salv. 181. Silvery, 

 striped with blackish ; a broad black spot on each side of the tail.

 species.

 no correct idea of them.
