above, and greatest distal width about j of eye. Upper lip thin, 

 tough, tight. Lower lip similar, only a little more fleshy on each 

 side of mandible. Teeth in jaws rather small, strong, tricuspid, 

 slightly compressed with median cusp greatly enlarged and pointed, 

 edges of teeth otherwise entire, and all uniserial. At base of each 

 maxillary a series of 4 small teeth, continuous with others in upper 

 jaw, and otherwise similar. No other teeth. Upper and lower 

 buccal folds rather broad, well developed. Tongue broad, fleshy, 

 depressed, front edge free and convex as seen from above, surface 

 finely papillose. Mandible strong, rami low, surface convex and 

 anteriorly well protruding in front beyond snout tip. Nostrils 

 together, anterior in a short cutaneous tube, forming behind into 

 a rather broad flap, and posterior a bean-shaped aperture close 

 behind. Interorbital broadly convex. Broad suborbital chain 

 completely covering cheek. Preorbital narrowest of suborbital 

 chain, and narrowest portion about half of eye. Postero-infraorbital 

 largest, its length about twice eye-diameter. Lower postorbital 

 larger than upper. Hind preopercle edge nearly straight and inclined 

 a little behind. Opercle width about If its length. Hind cutaneous 

 edge of gill-opening broad. 



Gill-opening forward about opposite hind pupil edge. Rakers 

 8 + 12, rather slender, elongate, lanceolate, tips pointed, about 

 §• of filaments. Latter 1| in eye. No pseudobranchise. Isthmus 

 broadly convex, membranes forming narrow free fold anteriorly. 

 Branchiostegals 4, subequal, strong. 



Scales large, firm, well exposed, free edges convex, cycloid, with 

 about 10 more or less reticulated radiating striae over exposures, 

 and all distributed in nearly even longitudinal series. Scales along 

 edges of body but little smaller than others. Body scales extend 

 out on anal base, where not much smaller than others and form a 

 sheath into which anal fin depresses. Caudal largely scaly basally, 

 scales at base but little smaller than others on side of body, though 

 becoming quite small out on lobes of fin sub-basally. Pectoral with 

 rather deep axillary depression. Ventral axilla with short and free 

 pointed scaly flap a little less than 3 in fin. Fins otherwise, and 

 head, naked. L. 1. evident only as first 3 tubes in course from 

 shoulder. Tubes simple, small and extend over first third in scale 

 exposures. 



Dorsal origin about midway between caudal base and hind eye 

 edge, first and second branched rays subequal and longest, depressed 

 fin half way to adipose fin origin. Adipose fin small, inserted a
