42 gangetic fishes. Order IV. 



body are covered with minute remote scales, which adhere 

 firmly. 



The first dorsal fin is rounded, slightly connected with the 

 second, and no higher : its rays are undivided and recurved ; 

 those of the second are recurved, and branch at the tops. The 

 pectoral fins are situated low, and are of an oval form, each con- 

 taining eighteen branched rays. The ventral fin is of an ob- 

 liquely hooded form, and oblong shape. The rays of the anal 

 fin are branched ; the tail fin contains eighteen. 



3d Species. — Gobius viridis. Plate XXXII. Fig. 12. 



A gobius with an eel-like body, with five rays in the first, 

 and twenty-six in the second dorsal fin, and with twenty-six 

 in that behind the vent. 



This perhaps may be the Gobius pectenirostris of La Cepede, 

 (Hist, des Poissons, Tome II. p. 542,) but the description 

 which he gives is so short, that I cannot ascertain the point. 



This small fish is found in the estuaries of the Ganges. 



The body is smooth, above of a dark green colour, spotted 

 with black, beneath white. The back and tail fins are colour- 

 ed like the back, and of the former the first, and the latter are 

 edged with black. The eyes are golden coloured. 



The lips are fleshy : the upper is double, the outer having a 

 sharp projection on each side ; while the inner of the upper 

 and the under lips are fringed, as it were, with short tendrils. 

 The teeth are remote, blunt, and parallel to each other. The 

 nostrils are near the eyes, which are quite contiguous to each 

 other, and the animal possesses the power of protruding them 

 very far, and of again drawing them within the level of the 

 head. They are small, and have oval pupils turned towards 

 the side of the head. The gill-covers consist of one plate with- 

 out scales, and each of their membranes contains three rays.
