FAMILY III. 



SCIENOIDES. 



This family is closely related to the Percoides, and even 

 presents nearly similar combinations of external characters, 

 particularly in the indentations of the preoperculum;, and in 

 the spines of the operculum ; but both vomer and palatines 

 are without teeth ; the bones of the cranium and face are ge- 

 nerally cavernous and form a muzzle more or less gibbous. 

 The vertical fins are frequently somewhat scaly. 



Some of the Scienoides have two dorsals, and others have 

 but one ; among the former we first find the genus, 



SciiENA, 



Whose common characters consist of a gibbous head, supported by 

 cavernous bones, two dorsals, or one deeply emarginate, whose soft 

 part is much longer than the spinous; a short anal, a dentated preo- 

 perculum, an operculum terminating in points, and seven branchial 

 rays. If it were not for the absence of the palatine teeth, these fishes 

 would resemble the Perches. The entire head is scaly; their nata- 

 tory bladder is frequently furnished with remarkable appendages, 

 and the stones in the sac of the ear are larger than in most fishes.(2) 

 We divide this genus as follows: 



Sci^NA, Cuv. 



Spines of the anal, weak; neither canini nor cirri. 



Sc. vmbra, Cuv.; Peisrey of Languedoc; Fegaro of the Ge- 

 noese; Umbrina of the Romans, &c. Six feet and more in 

 length; numerous branched appendages on each side of the na-

 a mountainous body. 



(2) This determination of the genus Scijena is in accordance with the opinion 

 of Artedi; it has been variously modified by Linnsus and his successors, but in 

 our opinion not very successfully.
