TEMNODON. 
Established by Cuvier on a fish remarkable by its first dorsal 
being very low, formed of eight feeble, continuous spines, but 
often difficult to see.

(SJcip Jack?) 
This is one of the most common fish in the market ; it is gene- 
rally found at Melbourne of a small size, but I have seen one 
in September, which was 2J feet in length. 
G-enerally it is of a very bright silvery colour, with the upper 
parts of the body, head, and upper fins of a dark olive ; the lower 
fins being white ; the eye silvery or rather yellow. 
This fish appears to be found in all the warm and temperate 
regions of the world, but it is not certain that several species are 
not mixed together. In some specimens I only see seven rays 
to the dorsal, and in a few the teeth are much more set apart 
than in others. I have also seen several times, at Melbourne, 
small specimens, called by the fishmongers Snubgall, which have 
the anterior part of the head shorter, and much more convex over 
the eye. 
At the Cape of Grood Hope, where it is very common, it is 
very often found of large dimensions. The young specimens are 
very brilliant, blue on the back, and green on the upper part of 
the head. The old ones are of a lead colour on the upper parts. 
NEPTONEMHS. 
Not one of the Australian fishes I have studied has caused 
such trouble to identify as this ; it is common on the Melbourne 
Market, and it is not likely, therefore, that it has escaped the 
attention of collectors and naturalists, but in the most modern 
authors I can find no description that can apply to it. 
It has much resemblance to the genus Trachynotus, and also 
with Fsenes, but it differs from the first in having no first dorsal 
spine directed forwards, nor its two first anal spines separated
