﻿Gobius, — 3d Div. gangetic fishes. 5B 



to about the length of a man's finger. The specimens I saw- 

 were somewhat putrid. 



The form tapers to the end of the tail. The colour is green- 

 ish, spotted with black, and having some white on the belly. 

 The hinder fin of the back, with those behind the vent, and 

 on the tail, are spotted with black. 



The head is oval, and broader than the body. The mouth 

 descends obliquely backward. Each nostril has only one 

 aperture. 



The edge of the back forms an arch. The lateral lines are 

 faint. The ve7it is nearly in the middle. The foremost dor- 

 sal fin slopes backward, and has six undivided rays, of which 

 the third is the longest. The pectoral fins are rounded, each 

 containing eighteen rays. The ventral fin has nine rays. The 

 tail fin is rounded, and contains twenty-three rays, of which 

 three on each side are short, and almost united. 



11th Species. — Gobius chuno. 



A gobius with seven rays in the second fin of the back. 



This minute fish, which is from one to one and a half inch 

 in length, is found in the estuary below Calcutta, and is of no 

 value eitheii for quantity or quality. 



The colour is whitish and diaphanous, with some dots on the 

 head. 



The head is wide and large. The mouth descends backward, 

 the under jaw being the longest. The structure of the teeth 

 in such a minute animal cannot be readily ascertained, al- 

 though these organs evidently exist. The et/es are far for- 

 ward. 



The lateral line is straight. The scales, although large, are 

 so thin that they cannot be seen without a magnifying glass. 

 The vent is near the middle.
