No. IX. — NEW SORTS FOR THE VICTORIAN 
FAUNA. 
During the publication of this paper, I have obtained three 
fishes that I had not observed previously \ two are new to 
science, and the third already described. 
One belongs to the genus Oligorus, which was formed by 
Dr. Gunther on a species of Grystes of Cuvier, but as I already 
mentioned in the first vol. of these Transactions, p. 53, he 
adds to it a large New Zealand sort, which evidently cannot 
remain in the same generic division. Having since obtained 
more information on this latter, which is the Hapuku 
of the natives of New Zealand and the Oligorus Gigas 
of Dr. Gunther, I proposed forming on it a genus that I 
named Hectoria in honour to the celebrated Dr. Hector 
(Notes on the Edible Fishes of Victoria in the Melbourne 
Exhibition Essays, 1872). 
The genus Oligorus is thus restricted to the Murray God, 
but I believe that two distinct species are confounded under 
this name. 
OLIGORUS MITCHELII. 
The head much broader ; the eye considerably larger, being 
contained only six times in the total length of the 
head and twice in the length of the snout to the anterior 
edge of the eye; the upper jaw is longer than the 
lower, which is not the case in Macquariensis. The distance 
between the eye is not contained quite three times in
