BY W. MACLEAY, T.L.S. 307 



a number of rather strong teeth on the angle and lower limb, those 

 on the latter pointing forwards ; infraorbital serrated. Operculum 

 with the lower spine long and sharp. Dorsal fins not quite 

 separate, the first spine very short, the second half the length of 

 the third, that and the fourth, fifth, and sixth about equal ; caudal 

 fin a little emarginate. Of an almost uniform pale pearly colour 

 with the tip of the lower jaw, a patch on the edge of the operculum 

 between the spines, and the dorsal, caudal, and ventral fins 

 blackish. 



This species was got in the Parramatta Eiver. It is quite 

 distinct from Z. colonorum, and yet in many resj)ects resembles it 

 extremely closely.
