 Length of head 4^ to 4|, height of body 5 to 6 in the total 

 length. Eyes diameter 7 to 8 in length of head, 2 diam. from 

 end of snout, and 2^ to 3 apart. Greatest width of head equals 

 ^ of its length. Snout not much swollen ; lower jaw slightly the 

 shorter ; distance between eye and maxilla about 1^ diameters of 

 orbit. Preopercle creuulate'd, with denticulations at its angle ; 

 opercle with two points. Snout with two open pores on its anterior 

 surface, and two more opening on the free edge of the skin ; lower 

 jaw with a small open pore a little below and to one side of the 

 symphysis. Shoulder-flap edged with numerous long ciliae. 

 Fins dorsal spines weak, with filamentous terminations, the 3rd 

 and 4th longest, | the height of body, and nearly twice as long 

 as the rays. Pectoral pointed and as long as the head. Ventral 

 reaches halfway to the vent. Second anal spine weak, \ to f 

 length of rays, and equal to 1 diameter of orbit ; length of base of 

 the fin equal to of that of soft dorsal. Caudal wedge-shaped, its 

 central rays much the longest. Scales cycloid on the head, ctenoid 

 on Uie body. Lateral lineon a raised" row of scales, becoming 

 straight above the middle of the anal fin, its tubes very arborescent 

 posteriorly. Air-bladder dividing anteriorly into two short, pro- 

 cesses, whilst springing from near its posterior extremity are two 

 more long processes which extend forward as far as the auditory 

 apparatus. Colour light brownish along the back, becoming
