scarcely differ, though the maxillary does not reach quite so far 

 back; the much larger and less numerous scales distinguish this 

 species from C. novce-zelandice. 



This interesting little fish was captured alive by Mr. R. J. 

 Kinghorn on 26th January, 1915. He discovered it while 

 digging for " Pippies " in moist sand which was washed by the 

 waves, but above the actual tide-level. It escaped when first 

 disturbed, and after swimming rapidly over a most erratic course, 

 buried itself in some loose sand. It was found a second time, 

 and was placed in a bottle with some sand, into which it dis- 

 appeared so suddenly that it was supposed to have been again 

 lost, until its slightly projecting eyes and snout were detected. 

 Mr. Kinghorn observed that it lay flat upon the sand when 

 burrowing, and, with a small wriggling movement, buried itself 

 in a fraction of a second. The fringes of cirri covering the 

 mouth and upper portions of the gill-openings doubtless serve to 

 prevent the entry of sand into these apertures, while the lower 

 parts of the gill-openings can be completely closed by the over- 

 lying membranes of the operculum and branchiostegals. 



Zoc5.— Narrabeen, near Sydney; Maroubra Bay, near Sydney; 

 Point Lookout, Stradbroke Island, Queensland. The specimen 

 in the Australian Museum from the latter locality is one of those 

 recorded by Ogilby as Leptoscopus macropygus. 



Family GOBIID^. 

 Genus Callogobius Bleeker.

 {Eleotris hasseltii Bleeker). Id., Weber, Siboga Exped., Ivii., 

 Fische, 1913, p.479.

 {Gobius mucosus Giinther). 



Weber having suggested that Gobius rmicosus belonged to the 

 genus Callogobius, 1 have compared specimens with his figure of 

 C. hasseltii {loc. cit., p. 480, fig. 98), and find that the two species 

 are very similar, and their generic characters identical. My 

 name Mucogobius, proposed for G. mucosus, therefore becomes a 

 synonym.
