tion the circumstances in which the Sagor differs from the de- 

 scription given of the Gagora. 



The Sagor above is of a green colour, with a golden gloss, and 

 adorned with several golden belts, descending to the lateral line. 

 The naked bone covering the head is distinct from that on the 

 back, is rounded before, and terminates behind in four lobes. 

 The bone on the back consists of two rounded lobes. On each 

 gill-cover are two naked bones, roughened with tubercles ; the 

 foremost being long and sharp at each end. The two upper 

 tendrils Teach to the middle of the pectoral fins, and the two 

 outer ones on the chin are only a little shorter. There is only 

 one bone on the palate, and it is divided into four lobes. The 

 lateral line, in its fore part, is covered with tubercles. The pec- 

 toral fins have only eleven rays each. The first seven rays of 

 the vent fin are undivided. In the tail fin there are only sixteen 

 distinct rays. 



7th Species. — Pimelodus arius. 



A Pimelodus with six tendrils not longer than the head ; with 

 the fin of the tail divided into two lobes ; with eight rays 

 in the back fin, the prickle being indented on both edges, and 

 ending in a flexible point much longer than the membrane ; 

 with twenty-two rays in the fin behind the vent ; with teeth 

 on the palate ; and with the sides unspotted and opaque. 



This is another fish, so like the Gagora, that, besides the 

 circumstances mentioned in the specific character, I shall only 

 notice what it differs in from the description of that animal. 



The Arms [Ari gagora) is found in the same places with the 

 Gagora, but seldom exceeds two feet in length. Its colours 

 are similar to those in the description ; but the spot on the se- 

 cond back fin is more distinct, nor have any of the back fins 

 a tinge of red. On its palate are two triangular bones, thinly
