fourth dorsal spine 3^; eleventh dorsal ray 2f ; third anal spine 3/o; 

 seventh anal ray 3^; caudal If; least depth of caudal peduncle 3^; 

 pectoral If; ventral 2; ventral spine 3^; snout 5^ in head measured 

 from tip of snout; eye 7; maxillary 2yo ; interorbital space 5. 



Body robust, elongate, compressed, profiles rather evenly and 

 similarly convex, so that contour is somewhat fusiform, and greatest 

 depth at base of fifth dorsal spine. Edges of body rounded, chest 

 broadly so. Caudal peduncle compressed, and least depth about f 

 its length. 



Head large, robust, slightly compressed, and with greatest width 

 swollen below. Upper profile more inclined than lower, nearh^ 

 straight, and but slightly concave over eye. Snout convex, its length 

 about half its width. Eye a little longer than deep, rounded, high, 

 and near first quarter in length of head. Mouth inclined obliquely, 

 and broad mandible protruding a little in front. Lips a little broad 

 and fleshy. Maxillary well exposed, reaching about f an eye- 

 diameter beyond eye, and its expansion about I of horizontal orbital 

 diameter. Bands of rather small fine teeth in jaws, a few canine-like 

 in front of upper and along rami of lower posteriorly. Rami of 

 mandible not elevated inside of mouth. Bands of minute teeth on 

 vomer and palatines. Buccal membranes broad in mouth. Tongue 

 broad, rounded and a little free. Nostrils close together on side of 

 snout above front of eye, anterior with a tube ending in a cutaneous 

 flap posteriorly. Posterior nostril midway between anterior and 

 upper front of eye. Preorbital narrow, its width about f horizontal 

 orbital diameter. Preopercular margin convex posteriorly, that 

 edge finely serrated, and about 3 large denticles at corner. Opercular 

 spines 3, median largest and closer to lower, also a little posterior. 



Gill-opening extending forward opposite front of orbit, and upper- 

 most margin horizontal. Gill-rakers vi, 3 + 8, vi, clavate, and longest 

 half of orbit or same of gill-filaments. Gill-filaments | of horizontal 

 orbital diameter. Pseudobranchiffi about f of filaments. Isthmus 

 broad, bevelled in front, and broadly keeled posteriorly. 



Scales all rather finely ctenoid, largest on opercle and middle of 

 side, and very small and reduced along edges of body, especially pre- 

 dorsal region and chest. On predorsal region, and cheek above, 

 scales more or less truncate. Scales disposed over trunk in more or 

 less longitudinal series, and somewhat inclined posteriorly, also
