it has light green vertebre, differs from the described specimens (Cat. N.Z. 
Fishes) in that the posterior end of the dorsal and anal fins is abruptly 
lengthened outwards, making it either a different variety or it may be even 
species. This is correct only, however, for some specimens.

The occurrence of this fish in the Mataura River is of considerable 
interest, as it is by no means common in Otago waters. This specimen 
was found dead on the Mataura river-bank at Gore, and was sent up to the 
editor of the Otago Witnsss for identification, and subsequently came into my 
hands on the 29th April, 1884. Gore is about thirty-five miles from the sea. 
The body was long and cylindrical, total length seven times that 
of the head, or six times greatest depth, and covered with large cycloid 
scales, adherent. Lateral line barely visible, straight. Eye in diameter 
equal to one-sixth the length of head, and placed one-third from the snout, 
pupil black, iris yellow. Maxillary terminates in narrow rounded point 
posterior to centre of orbit; mandible shorter than maxillary and toothless. 
Teeth fine and comb-like even row (cardiform) along maxillary, a few on 
vomer and some on palatines and tongue. Operculum and sub-opereulum 
fine transparent bones with rounded margins and much larger than pre- and 
inter-opercles. Fins fine, ventrals in advance of dorsal, anal in advance of 
adipose; caüdal deeply forked. In colour slaty-brown along back passing 
into slate-blue on sides and silvery-white on belly, which had patches of 
azure, no spots. Fins orange colour tipped with dark slate and white ; 
cheeks with slight golden tinge, also the belly. When fresh, it had a 
herring-like smell on boiling, and ate nearly as well as a herring; flesh 
white and delicate.
