T. longulus?, Macleay, from ‘“ Fresh waters inland from 
Port Darwin.” From the former it differs in the more 
slender body, the narrower interorbital space, the much 
larger mouth, the two opercular spines, the finely and 
evenly denticulated coracoid, the strength of the second 
anal spe, and the greenish yellow coloration of some 
of the fins. From the latter it differs in the more robust 
body and larger head, the wider interorbital space and 
longer and sharper snout, the feebler denticulation of the 
preopercle and the coracoid, the shape of the spinous dorsal, 
the strength of the second anal spine, and the coloration. 
The species also bears some resemblance to 7. elphin- 
stoniensis®, de Vis, a lacustrine form from Lake Elphin- 
stone’, from which it differs in the rather larger scales, 
deeper body, larger head, nearly smooth preorbital, 
much wider gape, double-spined operculum, and _ finely 
denticulated coracoid. 
Personally I was much pleased to obtain this speci- 
men, since it has been the means of clearing up in part the 
mystery hanging round a fish of which I had previously 
received reports from various sources. The most circum- 
stantial account given to me was by Mr. George Robinson 
and his father. These gentlemen tell me that about 
eighteen years ago when they were living on Gowrie Creek, 
near Toowoomba, after a heavy flood, the creek was found 
to be positively swarming with a fish which had been 
never previously known .in that district. So plentiful 
and voracious were they that the very children could 
pull them out by the score of an afternoon, using as bait 
a small worm or piece of meat. It was particularly 
remarked that these fishes were never caught in the deeper 
pools, but were confined to the swift running streams 
where the water was barely sufficient to cover them, but 
being discolored they were invisible until hooked. The

and Suttor Rivers, inland from Mackay.
