ones. In the fore part of the palate are four naked bones. 

 The nostrils are near the eyes, which stand far forward, are 

 large, and have their longest axis horizontal, while the pupil is 

 circular. The gill-covers contain each four plates, of which the 

 foremost is indented round the edges ; the two intermediate 

 ones are very small ; and the hinder one ends in a sinus, with 

 a blunt point on each side. 



The lateral lines may be traced to the end of the tail fin, and 

 are smooth. The scales are rather small. 



The first prickle of the first back fin is very short, as is also 

 the prickle of the second fin. The pectoral fins are blunt, al- 

 though the upper rays are the longest. Each contains nine- 

 teen rays, of which the two first and the last are simple, and the 

 intermediate ones are branched. The ventral fins entirely re- 

 semble tliose of the Coitor. The prickles of the fin behind the 

 vent are strong. The tail fin is blunt, and contains seventeen 

 distinct rays, besides some short compacted ones at each side. 



What I consider as a mere variety of the above mentioned 

 fish is called Nuria by the fishermen of the Yasor (Jessore, 

 Rennell) district. It grows to three feet in length ; but on 

 carefully comparing it with the above description, I see no 

 other difference, except that it has one ray less in the hinder 

 fin of the back, (having one prickle and twenty-four soft rays,) 

 which, in this genus, is of very little consequence, the number 

 being liable to more considerable differences in individuals, 

 allowed by all to belong to the same species. 



3d Species. — Bola coibor. 



A bola with nine prickles in the first dorsal fin, and one 



prickle, with twenty-four soft rays in the second ; with three 



prickles and seven soft rays in that behind the vent; with no 



bristle on the ventral fins ; and with all the lower parts yellow.
