which on the sides bears on other teeth, so as to be bifid in this 
part ; those placed at the lower part of the mouth are even bifid. 
Lingual teeth formed of two large ones ; canines very strongly 
serrated, even denticulated, at their under side, which is arched. 
The head has a rather pointed appearance, which is caused by 
the lips not falling, as in Qeotria ; the eye is small ; the 
branchial openings are much less distinct, being placed under a 
fold of the skin ; they number seven. The first dorsal is rather 
triangular, and situated at a considerable distance from the 
second, which is high at its beginning, and lowers considerably 
before it joins the caudal ; this last is rather pointed. 
The colour is of a blueish grey, darker on the back ; the head 
is yellowish ; the eye silvery ; the first dorsal is grey ; the second 
is bordered with pink, and has its posterior part black ; the caudal 
is of that last colour, but has a pink margin. 
These fish are commonly found in the Tarra at its lower part ; 
they are considered good food. Their motions are very rapid ; 
they are very voracious, and pursue any object in the water, and 
they adhere to it with an extraordinary and ferocious tenacity. 
Dr. G-ray’s figure {GhonAro'pt.) is copied from Richardson’s, 
which, as Dr. Gunther has already observed, is not correct in 
showing the dentition. I thought at first that the bifid, and 
sometimes trifid, teeth of the Yictorian specimens would consti- 
tute them into a separate species, but the coverings of the teeth 
fall off so frequently in the specimens preserved in spirits, and 
change so much the appearance of these organs, that, after 
examining many specimens, I believe they all belong to the same 
sort. 
The average length is from fifteen to seventeen inches. I have 
taken on one the following measurements ; —
