cheeks ; sometimes a black isli spot on suboperculum ; vertical

Cichlasoma mojarra, Meek, is founded on a very small 

 specimen with malformed spinous dorsal. I have carefully 

 compared the smallest examples in the British Museum 

 Collection with Dr. Meek's figure, and I am quite certain as 

 to the identity of C. mojurra with C. Salvini.
