Bod}' subelongate, compressed, with convex ventral profile; 

 forehead broad and flat; snout short, with the mouth oblique; a 

 band of acute teeth in both jaws; eyes large; preorbital smooth; 

 two separate dorsal fins, the first, with four or five flexible, 

 unarticulated rays; scales large and cycloid, the lateral line Httle 

 conspicuous. Air-vessel simple. Doi^sal and ventral fins with 

 elongate, filiform raj's in the male. (^Ktier). 



From the description of the only known species we also learn 

 that the lower jaw projects slightly beyond the upper; the max- 

 illary does not reach to the eye, and is almost entirely concealed 

 beneath the preorbital; that the teeth in the jaws are small, acute, 

 directed inwards, and arranged in a narrow band, the outer series 

 being enlarged and almost caninoid, while there are no perceptible 

 teeth on the j)alate. 



The absence of palatine teeth, presence of an inconspicuous 

 lateral line, and similarity in form of the sexes are the only 

 important characters which are available for the separation of 

 this from the succeeding genus, and it is quite possible that, when 

 examples of the two can be compared, the line of demarcation 

 will be found untenable, and Rhoiubatr actus will have to merge 

 in the older Pseudomugil.

Type : — Fsfiudomuc/il signifer, Kner. 



Distribution : —York Peninsula. In the Voyage Novara 

 it is alleged that the fishes from which Professor Kner's des- 

 cription was drawn up, were collected at Sydney, but this is 

 manifestly erroneous, no member of the family being so far 

 known with certainty to exist on the coastal watershed of our 

 dividing range south of the Richmond and Clarence District, 

 from whence the late Sir William Macleay described a species 

 under the name of Aristens lineatus. The locality here given
