the height of the soft fin. Anal fin as long as its distance

caudal ray 238 millimeters. 
Type in the Queensland Museum, Brisbane. 
Upper Condamine River, Southern Queensland. 
The type specimen of this handsome Terapon was 
brought to the Museum by Mr. D. O’Connor, who had 
received it from a correspondent at Stanthorpe. The 
example was almost immediately placed in my hands by 
Mr. de Vis for report thereon, with the result that I am, 
though reluctantly, constrained to consider it an 
undescribed species. I say “reluctantly” advisedly, 
because it seems to me that there are already an undue 
number of local species belonging to this genus described 
from the fresh waters of Queensland ; nevertheless, as 
this fish differs considerably from all the forms hitherto 
recorded, I have no option but to give it a provisional 
name. 
The nearest allies then of this new species are T'erapon 
truttaceus', Macleay, from the Endeavour River and
