Occipital process one-fifth of the distance from its base to the dorsal, 

 bordered by three scales. Interorbitals very slightly convex. Frontal 

 fontanel large, triangular, only slightly narrower than parietal, as 

 long as the parietal without the occipital groove. Second suborbital 

 with naked margins behind and below. Snout short. Mouth moder- 

 ately large. Lower jaw protruding beyond the upper when the mouth 

 is open. Maxillary not so large as the eye. Mandible equal to the 

 eye. Premaxillary with two or three, rarely four, small five- to seven - 

 pointed teeth in the outer row, and five large seven- to nine-pointed 

 teeth in the inner row. Maxillary with one to three broad seven- 

 pointed teeth. Dentary with five or six large seven- to nine-pointed 

 teeth followed by two or three very small, but multicuspid, teeth on 

 the side. 



Gillrakers about 5 -f 11. 



Scales cycloid, regularly imbricate, no interpolated scales or rows of 

 scales ; striae few, variable in number. Base of the caudal sometimes 

 a very little scaled, the broad terminal scale often wanting. Anal 

 sheath short, composed of four scales covering the bases of the first six 

 rays. Axillary scale developed. Pores on seven to eleven scales ; 

 lateral line slightly decurved. 



Origin of the dorsal a third of the length of the eye nearer the base of 

 the caudal than the snout ; penultimate rays 0.4 of the longest, which 

 is 2i to 2|- into the length. Origin of anal on the vertical from 

 the last dorsal ray; longest ray 1.66 in the base, which is 1.2 

 times the head. Ventrals on the vertical from the first or second scale 

 in front of the dorsal, ventrals just reaching the anal. Pectoral never 

 reaching beyond the second scale in front of the ventrals. 



Humeral spot round, very intense, surrounded by a light ring, very 

 frequently with a less intense dark bar extending obliquely downwards 

 and forwards and another shorter bar extending obliquely upwards 

 and forwards. A faint secondary humeral spot the width of two scales 

 behind the first. Lateral stripe sharp and very narrow, not reaching 

 the caudal, no caudal spot. Dorsal scales outlined with dusky. Top 

 of head very thickly covered with chromatophores. Fins all a little 

 dusky. Sides silvery, iridescent. Caudal peduncle as far as the front 

 of adipose, the adipose and caudal, except the lobes, very rich cherry- 

 red. Caudal lobes, anal, and dorsal canary-yellow.
