Head louger than deep ; upper lip thin, lower lip narrow. Gill-rakers 

 short, 13 on lower arch. Ventrals reach vent, nearly as long as head. 

 The outer ray of ventral and outer rays of caudal produced. Scales on 

 cheeks and occiput much smaller than elsewhere, in about 12 rows on 

 the cheeks. 



The fatty hump on forehead, which is usually seen on mature indi- 

 viduals in this genus, is wholly undeveloped. 



Color, in spirts, yellow olivaceous, with darker olivaceous waving- 

 streaks running horizontally between the rows of scales ; these lines be- 

 coming mere brown spots above and below, but forming two bands be- 

 hind the eye, which converge into one in front of the eye; under jaw 

 scarcely spotted except near the gape of the mouth. A dark brown 

 blotch between the soft dorsal and the lateral line extending around the 

 posterior part of the soft dorsal, /y-shaped, as seen from above, close 

 up under the fin, but not extending on it ; the dorsal fin with a dark 

 spot anteriorly, the margin of connecting membrane brownish along 

 whole of spinous portion. Teeth white. 



A larger specimen (17 inches in length) is darker everywhere, with 

 the dorsal, caudal and ventral fins dusky, and the blotch between soft 

 dorsal and lateral line less prominent. The ventrals are longer, reach- 

 ing third anal spine. 



Two fine specimens, numbered 26830, lof inches in length.
