82. Neetroplus Gunther. 



Neetroplus Gunther, Fish. Cent. America, 469., 1869. (Type, Neetro- 

 plus nematops Gunther.) 



This genus differs from Cichlasoma chiefly in having anteriorly a 

 row of flat, incisor-like teeth, behind which is a band of villiform teeth. 



In the numerous specimens of Neetroplus carpintis examined by 

 me, the incisor-like teeth are not always evident, which indicates 

 some doubt as to the validity of the genus.
