Genus PLATOPHRYS Swainson 



Eyes and color on the left side; body ovate, strongly com- 

 pressed; mouth of the large type, but comparatively small; the 

 maxillary one third or less of the length of the head; teeth 

 small, subequal, in one or two series, no teeth on vomer or 

 palatines; interorbital space broad and concave, broadest in 

 adult males; gill rakers moderate; dorsal fin beginning in front 

 of eye, all its rays simple; ventral of colored side on ridge of 

 abdomen; caudal convex behind; pectoral of left side usually 

 with one or more filamentous rays, longest in the male; scales 

 very small, ctenoid, adherent; lateral line with a strong arch 

 in front; coloration usually variegated. 



All the species are extremely closely related and can be dis- 

 tinguished with difficulty. On the other hand, the variations 

 due to differences of age and sex are greater than in any other 

 of our genera.
