Head deep, well compressed, and becoming more or less constricted 

 below. Snout rather broad, and convex, upper jaw projecting a little. 

 Eye anterior, without adipose lids. Maxillary reaching front margin 

 of orbit, and partially exposed. Mandible, with rami forming a right 

 angle, exposed median strip on chin rather broad. Teeth ciliiform, 

 uniserial, and rather long in jaw. Symphysis with usual process. 

 Tongue not free, fleshy. Preorbital finely serrate. Nostrils well 

 separated, posterior closer to upper front rim of orbit than to anterior. 

 Interorbital space broad, and a little convex. 



Gill-opening extending forward till opposite middle of eye. Gill- 

 rakers numerous, fine, slender, shorter than filaments which are about 

 I of eye. Pseudobranchice about half of orbital diameter. 



Stomach gizzard-like, muscular. Intestine long, with many convo- 

 lutions. Peritoneum dark brown. 



Scales moderately large. A long, pointed, scaly flap at ijase of 

 spinous dorsal and another between bases of ventrals. Soft dorsal and 

 anal covered with small scales over their greater portions. Base of 

 caudal scaly. 



Spinous dorsal inserted nearer base of caudal than tip of snout, and 

 second spine a trifle longest. Soft dorsal inserted nearly midway be- 

 tween origin of spinous dorsal and l^ase of caudal. A little less than 

 half of base of anal inserted before origin of soft dorsal, third spine 

 longest, second but little shorter, and first short. Caudal emarginate, 

 lobes pointed and producing a forked appearance when fin is not ex- 

 panded. Pectoral inserted a little above upper rim of orbit, and fall- 

 ing about opposite origin of spinous dorsal. Ventral inserted about 

 opposite middle of pectoral, and spine nearly f length of fin. 



Color in alcohol pale brown, back slightly darker, and tinged with 

 dull olivaceous. No traces of streaks on side. Base of pectoral 

 scarcely darker than rest of fin. Fins all plain pale brownish.

Type No. 9,771. Gabun country, West Africa. P. B. DuChaillu. 



Six co-types, also with same data. They seem probably related to 

 Liza schlegeli (Bleeker),* but that species is said to have but 30 scales 

 in a lateral series.
