sharply set off from the cranium, on which it does not encroach ; cra- 

 nium broad and flattish above; mouth moderate, with canine teeth, 

 which may be fairly large, or may be very small. Teeth on vomer 

 and palatines and sometimes on tongue. Dorsal fin continuous; last 

 soft ray of dorsal and anal produced; no scales on dorsal and anal; 

 caudal forked; pectoral falcate, not shorter than head, the lower 

 rays not produced. 



This genus, as here understood, lies very close to Aprion, which 

 differs mamly in the subcylindrical body, larger teeth, and especially 

 in the very short and broad pectoral fin, which is about half head. In 

 Pristipomoides the species with the deeper body have the pectoral fins 

 most elongate. 



In the closely allied genus, Eooseveltia, the cranium is narrower and 

 with thickened ridges. Apsilus and Tropidinius have the skull of 

 Lutianus, with the fins of Pristipomoides, the occipital crest being 

 extended on the frontal region. These genera must be considered as 

 allies of Lutianus rather than of Aprion. 



The species of Pristipomoides differ considerably among themselves, 

 and the group may admit of further generic subdivision. Bleeker 

 unites all of these nominal genera to Aprion. 



The recognizable subgenera may be thus compared: 



Pristipomoides: Canine teeth strong; body elongate; pectoral fal- 

 cate, but relatively short; no teeth on tongue (approaching Aprion). 



Platyinius: Canine teeth moderate or strong; body compressed, not 

 elongate; pectoral falcate, very long; no teeth on tongue. 



Bowersia: Canine teeth weak; body compressed, elongate; pec- 

 toral long and falcate; no teeth on tongue. 



TJlaula^ Chxtopterus, name preoccupied) : Canine teeth very weak; 

 body compressed, elongate; pectoral falcate; tongue with a patch of 

 teeth.
