BELONOPERCA, 10 new genus 



Type. — Belonoperca chabanaudi, new species. 



Body rather short, robust, compressed. Head large, with elongated 

 or attenuated muzzle. Eye moderate, little before middle in head. 

 Mouth protractile, lower jaw protruding. Maxillary large, well 

 expanded, with long slender supplemental bone. Teeth fine, villiform, 

 in bands in jaws, on vomer and palatines, none on tongue. Tongue 

 long, slender, free. Interorbital moderate. Cranium, preorbital and 

 maxillary more or less finely rugose striate. Preopercle denticulate. 

 Opercle with 3 spines. Gill rakers moderate. Scales finely rough- 

 ened, uniformly small. Caudal basally and over rays covered with 

 minute scales, fins otherwise naked. Lateral line complete. Two 

 dorsals, entirely separate, first with 7 strong spines and rayed fin 

 with weak spine and 10 rays. Anal with 3 slender, weak spines and 

 7 rays. Caudal truncate or slightly emarginate. Pectoral much 

 shorter than ventral. 



One species, of small size. Greatly suggestive, in a superficial way, 

 of the American Centropomus. 



Diagnosis. — Known by its pikelike appearance, separated dorsals 

 and reduced soft dorsal and anal rays. 



16 BtXos arrow; -jripK-q perch; with reference to its contour suggestive of an arrowhead.
