It was the oi'iginal intention of tlie autliors to revise all the Anstralian 

 species of the Family Oobiidae, but cirenmstanccs liave prevented us from 

 cai'ryiug out our design. We therefoi-e submit descriptions and figures of 

 such species as we have been able to deal with, and give refei-ences to tlie 

 others. We have been unable to allocate some of the species dealt with 

 to an}' genera known to us, but as we lack several important papers on the 

 classification of the Gobiidre, we have preferred to leave them under the 

 bi^oader headings Gohlus and Elcotn's rather than create unnecessary 

 additions to the already long list of Gobioid genera. 



We have had the advantage of examining the very large collections 

 contained in the Australian Museum, the Queensland Museum, the Macleay 

 Museum, and the South Australian Museum. These include numerous 

 tj'pes and cotypes, and many authenticall}' labelled specimens, while the 

 Australian Museum is fortunate in possessing a repi'esentative series of 

 Indian fishes from the collection of the late Dr. Fi'ancis Day. All these 

 have enabled us to clear up many points in the vSynonymy of the species 

 dealt with. 



We are greatly indebted to the Trustees of the Macleay Museum foi- 

 the loan of all the Gobies and Eleotrids under their charge. We also 

 have to thank Mr. Edgar R. Waite, Dirocttu' of the South Australian 

 Museum, for the loan of those in his collection. 



Key to the Subfamilies of the Gobiida\ 



a. Pectoral base very muscular and mobile ; eyes erectile Periophlhalminae . 



aa. Pectoral base not unusually muscular or mobile; eyes not erectile. 



b. Ventral fins more or less united, usually with an anterior membrane connecting 

 the spinesi Gohiinae. 



bb. Ventral fins separate, with no anterior membrane between the spines 



Eleotrinae. 



Family GOBIID^. 

 Subfamily PERIOPHTHALMINAE. 



Perio])ht}ialiiti)tae, Regan, Ann. Mag. Nat. Hist. (8), viii., 1911, p. 733. 



Eyes close together, prominent, erectile ; base of pectoral fin very 

 muscular. Pectoral radials elongate, inserted on a broad, laminar I'idge 

 of the cleithrum ; hypocoracoid and cleithrum enclosing a large foramen, 

 Vertebrae 25-26 (10-11+14-16). 



1 This membrane is present in some species of Zonogobius (Z. nuchifasciatus), 

 but is wanting in others (Z. semidoliatiis).
