Gobius. — 3d Div. gangetic fishes. 51 



The first back fin contains six undivided rays, of which the 

 two first are not separated by a membrane. The first ray of 

 the second fin is undivided, and the others branched. The 

 pectoral fins are rounded ; the ventral is circular, and contains 

 ten rays. The fin behind the vent has eleven rays, and that of 

 the tail has seventeen, and is rounded. 



9th Species. — Gobius giuris. Plate XXXIII. Fig. 15. 

 . A gobius with ten rays in the second dorsal fin, twenty-two 

 in each pectoral, and nine in the fin behind the vent. 



In describing the 8th Species, I have already mentioned the 

 affinity of this to the G. eleotris, but that fish has no spots on 

 the body. The Giuris has a strong affinity also to the Koker 

 of Dr Russell, (Indian Fishes, Vol. I. No. 51,) but differs in 

 having much larger fins, and in the number of rays which they 

 contain. 



In all the ponds and fresh water rivers of the Gangetic pro- 

 vinces this is a very common fish, and it is a light well-flavour- 

 ed food, much in request among the natives. It is from six to 

 twelve inches in length. 



The body is rough, of a dirty pale-green colour, with some 

 gloss of gold on the sides, and rather diaphanous below. On 

 the back and sides there are numerous black dots, forming 

 large irregular spots, shaped somewhat like clouds. The se- 

 cond back fin, and that of the tail, are spotted with black in 

 many rows. 



The head is rather wider than the body. The mouth is very 

 large, and descends backward. The jaws are flattened, the un- 

 der one being the longest, and the upper, in opening the 

 mouth, is protruded. The teeth are sharp, distant from each 

 other, recurved, and large, but unequal in size. The tongue is 

 smooth, is split in two at the end, and fastened its whole
