Fam. 3. SERRANID^. 



Perciform fishes with the second suborbital produced into a subocular 

 lamina (subocular shelf), usually with teeth on the palate, separate 

 lower pharyngeal bones, gill-membranes free from isthmus, 6 or 7 

 branchiostegal rays, and two nostrils on each side. Spinous dorsal well 

 developed ; soft portion of dorsal usually not much more developed 

 than anal ; latter usually with 3 spines. Ribs usually sessile on the 

 anterior vertebree, inserted on the transverse processes when these are 

 well developed. 



Mostly marine and represented over the greater part of the world. 

 Five genera have members in African fresh waters.
