1194. AGONOSTOMUS PERCOIDES, Giinther. 



Head 3f; depth 3f. Dorsal IV-I, 8; anal III, 9; scales 40 to 42-13. 

 Vilhform teeth in the jaws and on the vomer and palatines; upper lip 

 thin; maxillary reaching beyond front of eye ; interorbital space flat, 

 its width 4 in head, rather greater than diameter of orbit, which equals 

 length of snout. Origin of spinous dorsal midway between snout and 

 base of caudal ; length of anterior spine m<5re than half that of head. 

 Soft dorsal as high as the spinous ; caudal deeply emarginate ; anal fin 

 higher than soft dorsal ; pectoral as long as head without snout ; ventrals 

 somewhat shorter than the pectoral fins. Nearly uniform greenish (in 

 spirits); blackish blotches between the dorsal spines. (Giinther.) 

 Fresh waters of San Domingo and probably of other islands, (percoides, 

 7rep/coet(5fo, like a perch.) 

 Agonosloma percoides, GUNTHEK, Cat., in, 464, 1861, San Domingo.

Depth 4^ to 4-J- in total length (about 3| without caudal). Dorsal IV- 

 I, 8; anal III, 9; scales 40 to 42, 12 in transverse series. Small teeth in 

 jaws and on the vomer and palatines. Upper lip thin ; maxillary reach- 

 ing eye ; interorbital space convex. Spinous dorsal somewhat nearer 

 snout than base of caudal. (Giinther.) Fresh waters of the West Indies 

 and eastern Mexico, Vera Cruz, etc. (monticola, inhabiting mountains.)

 Body moderately compressed, rather thick behind the head ; upper ante- 

 rior profile slightly convex above the opercles. Snout obtusely conic. 

 Preorbital not toothed. Rather narrow bands of villiform teeth in the 

 jaws, on the vomer, and on the palatines. Upper lip thick ; mouth
