Depth of body nearly 2| in the length, length of head about 4. Upper profile 

 of head only moderately convex above and behind eyes. Snout a little shorter than 

 eye, diameter of which is about 35 in length of head : eyes separated by a narrow

 apart than those of upper. 10 or 11 slender, pointed gill-rakers of moderate length 

 on lower part of anterior arch. Scales all cycloid, 94 (to 98) in lateral line. Width 

 of curve of lateral line a little more than twice in length of head. Dorsal (112) 114
