Genus POMACENTRUS. 



The following is the history of the Pacific American species of Po- 

 macentrus. In 1845, Tschudi (Fauna Peruana, Ichthy., 17} 

 described the species Pomacentrus latifrons, from Huacho. We 

 have not seen this species but according to Tschudi's description it 

 must differ from all the other Pacific-American forms in having the 

 dorsal rays XIII, 20, instead of XII, 15.
