more or less oblique, quadrilateral scales with the apexes forming a 

 rounded angle at the postero-inferior corner of each scale, and a proximal 

 row of very oblique scales, which are only partly on the anal rays. Sheath 

 sometimes absent on posterior third of fin. Two complete rows of scales 

 included in lateral band below first dorsal and part of another row both 

 above and below. Lateral line of several incomplete series of pores along 

 the sides. 



Head short, rather tnuicate posteriorly, 4.63-4.93 in standard length; 

 head width 1.79-1.95 in its length. Dorsal outline of head flattened, 

 sloping slightly downward from nape to end of maxillary, tip of snout 

 rather broadly rounded. Ventral outline of head broadly and evenly 

 rounded from isthmus to tip of snout. Snout short, bluntly rounded from 

 both dorsal and lateral aspects, 3-3,54 in head. Eye large, 2.58-3.02 in 

 head. Upper edge of orbit reaching but not entering dorsal outline of 

 head, its diameter equal to or slightly more than shortest distance from 

 edge of orbit to preopercular angle. Adipose eyelid present, better devel- 

 oped anteriorly. Postorbital narrow, 2.42-2.72 in head. Interorbital 

 broad, slightly convex, 2.7-3.21 in head. Preopercle with a small, weak, 

 flat, closely appressed "spine" at its angle. Branchiostegal rays 6. 



Mouth terminal, very oblique, the lower jaw slightly included at tip, 

 the gape curved. Maxillary narrow, not or barely reaching anterior edge 

 of orbit, never to edge of adipose eyelid when mouth is tightly closed, 

 2.58-3.02 in head. Premaxillaries protractile, broadly dilated posteriorly. 

 Gape restricted at the corners of the mouth by a membrane between the 

 jaws. Upper jaw teeth anteriorly in a narrow band of small, pointed, 

 slightly curved, depressible teeth, narrowing laterally to a single row. 

 IVIandibular teeth similar to upper. No teeth on the vomer or palatines. 

 Gill-membranes not united, free from isthmus. Gill-rakers 17-19 on 

 lower limb of first arch. Pseudob ranch iae present. 



Dorsal II to V-I, 9-11. First dorsal short, spines flexible, origin 

 over or slightly before anal origin and slightly before to slightly behind 

 mid-point of standard length. Origin of second dorsal over about six- 

 teenth anal ray, ending above next to last anal ray. Caudal base to origin 

 of second dorsal 2.6-3 in standard length. Anal fin elongate, I, 24-28, the 

 margin slightly falcate, the posterior ray 2.1-2.3 in greatest height of fin. 

 Anal origin midway between caudal base and anterior edge of eye. Cau- 

 dal fin moderately forked, lower lobe slightly longer. Pectoral rays 13 or 

 14, the fin short and broad, its length 1.08-1.14 in head. Ventral fins I, 

 5, closely approximated, short, not reaching anal opening, their insertion
