and have circular pupils. The cheek-bones and spaces on the 

 nape are indented round the edges as if with short bristles. 

 The fore gill-covers are indented on the edges with wider in- 

 cisures, while the hinder plate terminates in a sinus, bounded 

 by two points. The bones supporting the gills are lined witli 

 a sinole row of tubercles, of which some are cylindrical and 

 smooth, and others conical and indented. 



Although the ridge of the back is sharp, and the edge of the 

 belly is rounded, the sides do not slope outward so much as in 

 the fishes of this genus before described ; still the transverse 

 section is triangular. The lateral lines may be traced to the 

 end of the tail fin. The scales fall easily off. Above each 

 ventral fin is a long scale-like apjiendant. 



The prickles of the back Jin are strongish ; the first is very 

 short, and the third is the longest. The prickle of the second 

 fin is short ; the first soft ray is undivided, and the others are 

 branched. The pectoral fins are sharp above, and each con- 

 tains seventeen rays, of which the first and two last are undi- 

 vided and the intermediate ones are branched. The ventral 

 fins entirely resemble those of the coitor, but have stronger 

 prickles. The anal fin slopes gradually from before backward ; 

 its prickles are very strong, and its soft rays branched. The 

 tail fin is blunt, and contains seventeen distinct rays, besides 

 some short ones, closely compacted at each side. 



6th Species. — Bola ? coioides. 



A bola? with eleven prickles and fifteen soft rays in the 

 back fins, which are united ; with three prickles and eight soft 

 rays in the fin behind the vent ; and with the body spotted 

 with round red and black spots. 



This fish agrees so well with the description of the Me- 

 dinawa bontoo of Dr Russell, (Indian Fishes, Vol. II. No. 128,)
