 Type localities : — Gwydir River N.S.W. (T. unicolor). 



Endeavour River, N.Q. (T. truttaceus). 



Fresh waters inland from Port Darwin, N.T. (T. longulus). 



Lake Elphinstone, M.Q. (T. elphinstonensis). 



Upper Condamine River, S.Q. (T. idoneus). 



Body elliptical or elongate-elliptical, the dorsal and ventral contours sym- 

 metrical or the former a little more arched, its width 1-5 to 1-9 in its dejDth, which 

 is 2-75 to 3-5 in its length and from one twelfth more to one fourth less than the length 

 of the head ; caudal peduncle as long as to two fifths longer than deep, its least depth 

 7-5 to 10 in the body-length. Head about four ninths longer than deep, its upper 

 profile linear or feebly concave, that of the nape gently rounded, its width 1-5 to 2 in 

 its length, which is 2-7 to 3-2 in the body-length. Snout broadly rounded, its length 

 3-1 to 3-66 in the length of the head ; lips moderate. Eye rather small, its diameter 1-15 

 to 1-75 in the length of the snout and 2 to 2-6 in the postorbital head ; interorbital 

 region flat or feebly conve;s;, its width 1-25 to 1 -66 in the length of the snout. Maxillary 

 extending to the vertical from the anterior border of the eye or even to that of the 

 pupil. Preorbital entire or wth a few coarse denticles posteriorly ; hinder limb of 

 preopercle serrated, the serrse disappearing on the broadl}^ rounded angle ; opercle 

 with a short, stout pungent spine, above which is a more or less blunt point ; post- 

 clavicle with some coarse denticles. 



Jaws with a broad band of villiform teeth and an outer series of enlarged fixed 

 teeth, which are separate and somewhat recurved ; roof of mouth toothless. 



' Latnia brevispinis Steindachner has been briefly described from Cape York. Such characters 

 as are given agree with those of Therapon unicolor Gunther, with which Steindachner"s species is 

 probably identical.
