posterior much larger and anterior with cutaneous rim. In- 

 terorbital broadly depressed and very slightly convex. Pre- 

 orbital a little long, width 3/4 its length and latter 2 in eye 

 horizontally. Postorbital width about i 1/4 in pupil, other 

 suborbitals all narrow. Hind preopercle edge slightly convex 

 and inclined anteriorly. 



Gill-opening extends forward to about middle of head or 

 opposite hind edge of pupil. Gill-rakers about 2 -f- 6 short 

 weak points, much shorter than longest filaments, about 1/4? 

 their length. Gill-filaments 2 in eye horizontally, pseudo- 

 branchiae 2 1/2. Teeth 2 ?, 4-?, ?, hooked and with slight 

 grinding-surfaces. 



Scales in lengthwise rows parallel with 1. 1., mostly uni- 

 form or all rather broadly exposed, and those on chest slight- 

 ly smaller. Predorsal scales not crowded. L. 1. complete, 

 decurved nearly to lower third in greatest depth and ascends 

 a little low at first along side of caudal peduncle. Tubes 

 simple, extend well over exposures of scales or for first 3/4 

 at least. 



Dorsal origin about midway between front nostril and cau- 

 dal base, graduated down from first branched ray which 

 longest, depressed fin reaching i 4/5 to caudal base. Anal 

 origin behind last dorsal ray, graduated down from third 

 simple ray which highest and depressed fin reaching i 1/2 

 to caudal base. Caudal (damaged) apparently emarginate. 

 Pectoral reaches 3/4 to ventral origin, which opposite dor- 

 sal origin, and ventral reaches anal. Vent close before anal.
