 Snapper. 



Head 314 ; depth y/2 ; D. IX, 13; A. Ill, 8; scales about 52 to 

 base of caudal; 6 scales between origin of spinous dorsal and 

 lateral line; 12 scales between origin of spinous anal and lateral 

 line; mandible 2V10 ii^ head; fourth dorsal spine 2^.^ ; third anal 

 spine 4^ ; second dorsal ray 334 ; second anal ray TiVs ', least 

 depth of caudal peduncle 3; ventral 1^/7; snout 2^4 in head, 

 measured from tip of upper jaw; eye 5^2 ; maxillary 3; interor- 

 bital space 3^. Body elongate, and back little compressed or 

 elevated. Head small, compressed, and upper profile nearly 

 straight from tip of snout to nape. Snout rather long, pointed. 

 Eye circular, a trifle anterior. Mouth large, and mandible 

 strongly projecting. Maxillary oblique, reaching posterior nos- 

 tril, and falling well short of front of orbit. Distal expansion of

 caudal. On dorsal and anal a patch of small scales before base 

 of each spine or ray. Scales on predorsal region and along bases 

 of fins reduced in size. Tubes of lateral line branched. Spinous 

 dorsal inserted a little behind ventral, margin slightly convex, so 

 that fin is graduated from fourth .spine, which is longest. Rayed 

 dorsal inserted before anal or a little nearer base of caudal than 

 orbit. Anal spines graduated to third, which is longest, and rayed
