(Plate xiii., fig. 1). 



Kypoplectrodes jamesoiii Ogilby, Proc. Roy. Soc. Q'land, xxi., 

 1908, p, 16. 



I collected an example of this species, 110 nun. long, at 

 Cowan Creek, a salt-water branch of the Hawkesbury River, 

 which is figured on PI. xiii. It differs from ;i More ton Bay 

 specimen received from Mr, J. D. Ogilby, only in having 

 the maxillary bone larger and reaching to below the hinder 

 margin of the eye instead of only to its centre. Another smaller 

 specimen has been presented by Dr. R. Pulleine who dredged ii 

 at Port Curtis, Queensland.

Mitchell's figure of Cernua bidyana from the Karanla River 4 

 New South Wales, leaves little doubt that it represents the 

 Therapon ellipticus of later writers, though the fin formula given 

 by him — D. xi./?, A. iii./6, V. i,/6, is very different to what is 

 found in that species. I know of nothing, however, having any 

 such number of spines and rays, while it must be noted that the 

 figure shows them to be more in accordance with T. ellipticus. 

 The few notes given relating to colour and the sound-produciug 

 habit also agree with what is known of the Silver Perch or 

 Grunter, though they might also apply to related species: and 

 finally, T. ellipticus is apparently a common form in all the 

 western rivers of New South Wales.
