74S ON SOME AUSTRALIAN ELEOTKlNiE, 



Pale reddish-brown above, yellowish below, the head darker, 

 everywhere densely punctulated with lilackish dots which are 

 often concuri-ent, forming two more or less conspicuous series of 

 dark spots, one along the dorsal profile, the other along the 

 middle of the body, the latter terminating in a blotch which is 

 alwa3's present at the base of the caudal fin; a pair of oblique 

 brown bands from the eye across the opercles generally present; 

 first dorsal pale yellow with a basal, median, and marginal dusky 

 band; the second similar but with four or five narrower bands; 

 caudal with about eight irregular transverse bars, which often 

 form a network; anal and ventrals gray, with or without micro- 

 scopic dusky dots; pectorals yellow, with a more or less faint 

 darker basal band. 



In the breeding season the upper surfaces, dorsal and caudal 

 fins are deeply tinged with salmon colour. 



I found this to be the most al)undant species in the waterholes 

 near Liverpool on the occasion of the \isit above referred to, when, 

 like the two other species obtained at the same time, they were 

 busily engaged in the duties of reproduction. Suljsequently I 

 obtained a number of young specimens, under two inches in 

 length from a waterhole at Camden Park, but failed to catch any 

 adults. 



The Flat-headed Gudgeon is an inhal)itant of the coastal water- 

 shed of New South Wales from the Richmond River — whence 

 Krefft records it — southwards; it is abundant in the metropolitan 

 district, and the limit of its range inland a^Dpears to be somewhat 

 similar to that of Krefftius anstvalis or extending to an altitude 

 of about one hundred feet above the level of the sea; exactly how 

 much further southward it ranges I am unable to say. 



This species never attains to the size of the two preceding, the 

 largest example, of twent}' three utilised in the preparation of 

 the above description, barely measuring 100 millimeters.
