Family — Sci^Nid^, Cuv, 



Branchiostegals seven. Pseudobranchise sometimes concealed. Body compressed and 

 rather elongate. Eyes lateral, of moderate or small size. Mouth in front of or 

 below snout. Cheeks unarmed : opercles sometimes weakly armed. Muciferous 

 system on the head well developed. Teeth in villiform bands : canines present

 spines of first dorsal usually feeble : anal with two spines : pectoral rays 

 branched : ventrals thoracic, having one spine and five rays. Scales ctenoid.

Genus — Scijena, Cuv. 



Johnius, BIocli : Corvina, pt., Cuv. ; Leiostomus, pt., Cuv. & Val. : 

 ttomoprion, Holb. 



Pseudobranchia. Body oblong. Eyes of moderate size, and the inter-or- 

 bital space rather broad and slightly convex. Snout rounded ; the upper jaw 

 longer than the lower, or both equal. Cleft of motitJi horizontal or slightly 

 oblique. Barbels absent. The outer row of teeth generally the largest : 

 canines absent. Air-vessel present. Pyloric appendages Jew, or in moderate 



numbers. 



This genus has been subdivided artificially, in accordance to the 

 length of the second anal spine, as follows: — (1) weak and about half 

 the length of the first ray, Scieena : (2) moderately strong and nearly two- 

 thirds as long as the first ray, Johuius : (3) very strong and about 

 equalling the first ray in length, Corvina.
