7. Otolitiius argenteus. 



Otolithus argenteus, (Kuhl & v. Hass.) Cuv. & Val. v. p. 62. 



Skin of an adult specimen. 



This is another marine species, penetrating to Nepal. 



8. Trachynotus ovatus. 



Gasterosteus ovatus, Linn. Syst. Nat. i. p. 460. 



Mookalee-parah, Rnss. ii. p. 39, pi. 154. 



Trachynotus ovatus, Gtlir. Acanthopt. Fish. ii. p. 481. 



Skin of a half-grown specimen. 



A species found from between the tropics in the Atlantic and 

 Indian Oceans to the coasts of Australia. I do not know of another 

 instance where the species has been found in a river. 



8a. GoBius GiURis. 



" Gobius giuris, Buch. Ham.," Gthr. Acanthopt. Fishes, iii. p. 21. 



One specimen.

Two coloured drawings. 



I am not quite certain about the correctness of my determination, 

 as the drawing represents a very light-coloured, uniform fish, whilst 

 the true barca is dark and dotted with black. The forms, however, 

 are the same in both.
