peduncle strongly compressed, rather deep, and least depth about 

 f its length. 



Head strongly compressed, rather deep, and profiles more or less 

 similarly convex. Snout rather blunt, rounded, convex, and upper 

 profile pronouncedly convex. Eye circular, rather large and well 

 anterior. Adipose tissue developed. Mouth a little inclined and gape 

 extending nearly f length of head. Maxillary slender, long, and 

 furnished with a single series of fine or minute teeth to its distal ex- 

 tremity which reaches almost to gill-opening in front of origin of 

 pectoral. A similar series, though very minute, along margin of 

 mandible. Vomerine teeth a little larger than those on palatines 

 which are very small and uniserial. Also a still smaller series on each 

 pterygoid. Symphysis of mandible reaching about opposite posterior 

 nostril. Tongue small, little free, rounded, reaching forward till a 

 little in front of anterior orbital rim and with a free asperous patch 

 above. Nostrils close together, superior and a little nearer front rim 

 of orbit than tip of snout. Interorbital space with a slightly elevated 

 median ridge so that it is a little convex. Opercle and top of head 

 posteriorly with varied shallow flutings. Cheek with shallow perfora- 

 tions, and some above eye posteriorly. 



Gill-opening extending forward till opposite front rim of pupil. 

 Rakers about 14 + 20?, slender, long, and longest much longer than 

 filaments. Pseud obranchise smaller than filaments. Isthmus rather 

 broadly rounded though compressed above. Shoulder-girdle notched 

 once on each side below for reception of interopercle, and above behind 

 opercle an adipose-like tract. 



Scales cycloid, large, and caducous. Dorsal and anal with scaly 

 basal sheaths. Scales on base of caudal rather small. Pointed 

 axillary flap at base of pectoral f length of fin and inner rays of each 

 fin approximated. A similar ventral flap. 



Origin of dorsal nearer base of caudal than tip of snout and first 

 branched ray longest. Anal inserted about opposite first fourth in 

 length of depressed dorsal or much nearer origin of pectoral than base 

 of caudal, and its anterior rays elevated. Caudal forked and lobes 

 pointed. Pectoral low and reaching origin of ventral. Tip of de- 

 pressed ventral reaching at least opposite origin of dorsal. Vent 

 close in front of anal. 



Color in alcohol pale brownish, paler or whitish below. Back with 

 edge of each scale sprinkled with a series of brownish dots. A double 

 series of brownish dots down middle of back. Top of head, snout, and 

 opercle brownish with darker brownish dots. Upper posterior portion
