The height of the body is equal to one-third of the total length 

 without caudal ; cleft of mouth obliquely running upwards, as in the 

 genus Iluro ; the length of the head is contained twice and one-half 

 in the total length ; the diameter of the eye is less than the length of 

 the snout, and equal to the space between the eyes. The pectorals 

 are rather narrow at the base, with eleven rays, situated just above 

 the ventrals, which are furnished with one spine and five rays. The 

 anal has two spines and nine rays. There are only six spines in the 

 first dorsal, the first of which is the smallest, the last being about 

 as long again as the first ; the third spine is the longest, and is but 

 slightly larger than the diameter of the eye. A short space, about 

 the length of the last spine, divides the first from the second dorsal, 

 which has one spine and nine rays. The scales are of moderate size, 

 thirty on the lateral line. 



Coloration uniform brownish ; all the scales dotted with small 

 black spots forming crescent-shaped and triangular marks on the 

 sides. Caudalis truncated. 



Hab. Cox's River, County Philip, New South Wales.

The height of the body is one-third of the total length (without 

 caudal fin) ; the diameter of the eye is equal to the length of the 

 snout, as long as the space between the eyes, and nearly one-fourth 

 of the length of the head. There are two spines on the operculum, 

 the lower one with two points. Caudalis truncated ; the fourth and 

 fifth dorsal spine longest. 



Coloration uniform silvery on the sides ; the lateral line divides 

 the brownish and silvery hues ; ail the scales dotted with fine black 

 spots, those of the sides having a free space in the centre. Fins 

 black-dotted, and the first ray of the ventral fin tapering into a long 

 filament, which is equal to the length of the head. 



Hab. Murray River and its tributaries.

Body stout, its depth in front of the dorsal fin being nearly one- 

 eighth of the total length without caudal. The length of the head 

 is one-sixth of the total without caudal, and equal to the height of 

 the body. Eye of moderate size, one-fourth of the length of the 

 head, and equal to the extent of the snout. The length of the pec- 

 toral fin is one-third of the space between its root and that of the 

 ventral ; the ventrals are of the same length, and almost in the 

 middle between the vent and the root of the pectorals. The anal, if
