 1194. AGOXOSTOMUS PERCOIDES, Guuther. 



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

 Vilhforiu teeth iu the jaws and on the vomer and palatines; upper lip 

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

 its Avidth 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 more 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, (pereoideis,
