232 SERRASALMO STAGNATILIS. 



Another drawing resembles the last, but is con- 

 sidered to be distinct both by Mr. Schomburgk 

 and the Indians. It diflfers in the colour of the 

 upper part of the body, in the form of the adi- 

 pose fin, which in the last seems to have indica- 

 tions of rudimentary rays, and no spine is repre- 

 sented anterior to the dorsal fin ; it possesses the 

 same brilliant colouring of the gill-covers and belly. 

 These may be incidental also to particular sea- 

 sons.

 length, and is found in the Upper Essequibo. The 

 head is greenish; gill-lid, belly, pectoral, ventral, and 

 anal fins vermilion ; body blue ; caudal fin greenish. 

 The eye is yellow ; nostrils single, placed near the 

 eye. Operclcs striated. Lateral line is nearly straight, 

 a little bent near the head, and running along the 

 middle of the body. Body compressed, ending in a 

 keel ; teeth sharp, triangular, serrated ; jaws strong, 

 the lower slightly produced. Its resorts are in 

 standing pools, called kiraha^hs, where they live an 

 enemy to every other tribe, and are not less vora- 

 cious, although armed with less power, than its 

 kindred fish, the pirai." (Plate XYIII.) The length 

 of the drawings is stated to be eight inches and a 

 half; the depth of the fish, below the dorsal fin, 

 three inches and three-quarters.
