80 NEW GENERA AND SPECIES OF AUSTRALIAN FISHES 



upwards, with the result that I find a single series of slender 

 simple teeth present in all specimens under six inches long. 



That the species here described is not a true Mugil is evident 

 from the presence of well developed teeth in the upper jaw, but, 

 in view of the discovery above recorded with regard to Liza 

 peronii, I prefer to wait until larger examples are procured before 

 removing it from that genus.

Cestr.eus norfolcensis, sp.nov. 



D. iv. i 8. A. iii 9. Sc. 46-47/12. 



Body oblong and moderately compressed, the ventral proBle 

 much moi'e convex than that of the dorsal, which is almost linear 

 in advance of the fins. Length of the head 3|- to 4, depth of the 

 body 4i to 4^ in the total length; width of the body below the 

 origin of the first dorsal fin 2i to 2-^ in its depth; depth of the 

 head If to If, width of the head 1| to 2, of the interorbital region 

 3 to 3i, diameter of the eye 4 to 4Jjj- in the length of the head; 

 interorbital region slightly convex; snout obtuse, one-fourth of a 

 diameter longer than the eye, its upper profile nearly flat. Mouth 

 moderate, with lateral cleft, the lips thin; pi'emaxillaries narrow, 

 evenly rounded below; maxillary not reaching quite so far as the 

 vertical from the anterior border of the eye and longer than its 

 diameter, its outer margin not concealed by the preorbital; lower 

 lip included; dentary bones of the lower jaw forming a veiy 

 obtuse (almost rounded) outline in front, without anterior 

 notch; the articular Ijone extending backwards to beyond the 

 middle of the eye. Upper jaw with a single series of rather 

 strong teeth, which are narrow at the base and much swollen and 

 tricuspid distally, the middle cusp being much the longest and 

 strongly curved inwards; lower jaw with several series of well 

 developed cilia, the outer row being separated from those suc- 

 ceeding it by a naked interspace; vomer, palatines, pterj^goids, and 

 tongue smooth. Adipose eyelid rudimentaiy. Preorbital not so 

 wide posteriorly as the pupil, with the hinder half of the lower 

 and the posterior borders denticulated, the former sinuous, the
