emarginated below these ; their number is fifteen, with their first 
third, at least, covered with small scales. 
The upper parts are of a very dark blue, and the lower of a dirty 
white ; the lips are pink ; the eye yellow ; the sides of the head 
have a copper tinge ; the base of each scale of the body, being of 
a bright silver colour, gives the fish the appearance of having 
longitudinal lines ; the fins are yellow, with their base blue and 
their extremity black ; the ventrals are whitish. 
This sort attains large dimensions. I have one specimen which 
is about 21 inches long. It is much esteemed as food. 
AGOlSrOSTOMA. 
Genus formed by Dr. Gunther on the sorts of Mugil, which 
have an elongate muzzle and teeth on the vomer. The first of 
these mentioned by authors was observed by Forster, and called 
by him Ilugil Alhula. Cuvier and Valenciennes changed this 
name to Miigil Forsteri. Eichardson (“ Zoological Transactions ”) 
placed this sort in the genus Bajaus, of which it has most of the 
characteristics, and describes another sort under the name of 
Biemensis. It has been stated that the common Mullet of the 
Melbourne Fish Market was the Agonostoma Forsteri; but this 
is a New Zealand sort, and the fish alluded to belongs to Biemensis. 
I know that this is in conformity to the opinion of Dr. Gunther, 
who, in his Catalogue, unites the two sorts, but the difierence in 
the numbers of the fine rays separates them clearly.

Eichardson gives the following numbers to the rays : — 
D. 4 10. A. 3 /12. C. 14 5/4. P. 15. In most of the Mel- 
bourne specimens, I find one more branched ray to the anus, that 
is, thirteen ; but in a few I find also twelve. 
The upper parts are of a greyish blue, with green tinges on 
the body, and brown on the head ; the lower parts of the body 
are silvery ; the upper and pectoral fins are light grey ; the
