separated them into their genera and in some cases into their species. I have to thank 

 Dr. Annandale for suggesting new names and for revising my manuscript. 



Family GOBIIDAE. 



Sub-family GOBIINAE. 



Genus GOBIUS Linnaeus. 



Gobius ostreicola Chaudhuri.

1916. Gobius ostreicola, Bhattacharya, Mem. Ind. Mus., V, p. 383 (larval stages). 



There are altogether six specimens in the collection. They were collected in the months 

 of September and December, 1914, near Manikpatna in the oyster-beds.

Fifteen specimens of this species were collected on the oyster-beds near Manikpatna in 

 December, 1914. The species differs from the others included in the genus in the posses- 

 sion of a distinct emargination at the anterior extremity of the tongue. The emargina- 

 tion is not so deep as it is in the species of Glossogobius, from which genus the species can 

 be readily distinguished by the presence of free rays to the pectoral fin. 



The emargination of the tongue has been considered to be a character of generic im- 

 portance but I refrain at present from erecting a new genus for G. albopunctatus, because 

 the Indian species that have hitherto been referred to the genus Gobius are in need of revi- 

 sion. 



Distribution. — The seas of India to the Fiji Islands and Port Essington. Australia. 



Genus GLOSSOGOBIUS Gill. 



Gill 1 defined this genus as follows : " Glossogobius has a depressed head, protruding 



lower jaw, an anteriorly free and deeply emarginate tongue, and several rows of stout 



teeth in each jaw, the outer of which are hooked backwards." Quite recently the definition 



has been amplified by Jordon and Snyder, 2 and also by McCulloch and Ogilby. 3 The ampli-
