profile of the head is slighlv concave, but swells out towards the 

 snout into a rather prominent convexity truncate in front. The 

 cleft of the mouth is slightly oblique, the lower jaw distinctly 

 longer than the upper, the maxillary large, triangular, naked and 

 extending to, or very nearly to, the vertical from the posterior 

 margin of the eye. The teeth in the jaws are numerous in broad 

 viliform bands, those on the vomer are situated on a very 

 prominent horse-shoe shaped bony protuberance. The prseoper- 

 culum has a double ridge, both quite smooth ; the operculum has 

 one membranous point. The dorsal spines are very strong, the 

 first very short, the last less than half the length of the second ; 

 the first anal spine is very short : the caudal fin is rounded. The 

 lateral line follows the curve of the back. Colour (in spirits) pale 

 brown, the membranes connecting the spines of the first dorsal 

 fin, and the rays of the pectorals, black. Length 5 inches. 

 From fresh water inland from Port Darwin.

Species 139. Therapon niger. Casteln. 



Klunzinger thinks this fish is identical with Therapon ellipticus

 habitats are far removed from one another; the one inhabiting 

 the rivers of the Murray system, the other those of Western 

 Australia.
