 caudal) ; cleft of the mouth of moderate width, the maxillary ex- 

 tending to the vertical from the second thii'd of the eye ; the length 

 of the maxillary is one-third of that of the head. The greater portion 

 of the iuterorbital si)ace is scaly ; it is concave, and its width is 

 much more than the diameter of the orbit. The whole of the lower 

 eye is situated before the upper. Teeth very small, in a single series. 

 Anterior dorsal rays much shorter than the middle ones, which are 

 two-fifths as long as the head. Caudal fin a little less than one- 

 sixth of the total length. GiU-rakers lanceolate, rather short, half as 

 long as the eye. Brownish-yellow, with numerous larger and smaller
