136 PISCES. 



of Pentapoda, those whose mouth is less cleft, head more scaly, 

 body less elevated, and whose caudal is covered with scales to the 

 end.(l) 



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

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

 the angle of the jaws.(2) All these fishes have a pointed scale be- 

 tween the ventrals, and one above each of them. 



A third tribe is also composed of a single genus. 



Cantharus, Cuv. 



Teeth short and crowded, or bent and crowded (en cardes serrSes), 

 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; Sparus canth. , L. ; Rond. 1 20, and Duham. 

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

 brown; some small rough teeth behind the bent ones. 



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

 the teeth bent.(3) 



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

 genera. 



Boops, Cuv. 



Teeth of the external row trenchant, mouth small and nowise pro- 

 tractile. Several species are found in the Mediterranean. 



B. vulgaris; Sparus boops,L..x Rond. 136. 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. More oval; stripes of a 

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

 and emarginated. 



Oblada, Cuv. 



Differs from Boops in having small crowded teeth behind the inci- 

 sors, which somewhat approximates this genus to Cantharus.

 convey no correct idea of them.
