in the market, although not very good for the table: these are 
the M. (Glyphidodon) nigroris, called the “ black perch,” and the 
Glyphidodon Victorie, commonly called the ‘rock perch.” The 
Parma squamipennis has occurred also to me not very uncom- 
monly in the bay. Several brilliantly coloured fish of the family 
Labride occur as rare occasional visitors, but they are not worth 
special notice, the commonest and best-known being that called 
“ narrot-fish ;” it is the Labrichthys ephippium.. The Labrichthys 
laticlavius, L. psittacula, and several others also occur occasion- 
ally. A much esteemed fish in the Yarra and other Victorian 
rivers is called “black fish” by the colonists; it is abundant, 
and sometimes exceeds a foot in length: it belongs to the genus 
Gadopsis, so remarkable for combining a spiny first dorsal fin 
with all the other characteristics of the Anacanthini; it is a 
mere variety, apparently, of the fish called “freshwater trout” 
in the Tasmanian rivers, the Gadopsis marmoratus. The Lotella 
callarias is a rare visitor, confounded with the Pseudophycis bar- 
batus and two other species of Pseudophycis under the com- 
mon name of “cod” and “rock cod” by the fish-dealers. The 
“flounder ” of the colonists is a good table fish, with which the 
market is now regularly supplied; it seems peculiar to these 
seas, and is the Rhombosolea flesoides. A true sole (Solea), 
nearly allied to the Solea margaritifera, also occurs, although 
rarely, at the Heads. Amongst the Siluroid fishes the most 
important is the Copidoglanis tandanus, which is now regularly 
supplied to the Melbourne market~by railway from the river 
urray, under the name of “ Murray catfish.” The Yarra Yarra 
and some other of the rivers near the southern coast contain in 
great abundance a beautiful and active fish, excellent for the 
table, and affording capital sport to the angler. By ichthyo- 
logists following the classification of Cuvier it would be referred 
to the Salmonide, the adipose second dorsal fin being well 
marked; and so much does it resemble a grayling, in the cu- 
cumber smell when caught, in general appearance, habits, mode 
of rising to the fly, and playing, as well as in flavour, that 
anglers are in the habit of calling it now the “ Australian gray- 
ling ;” its close resemblance in food and habits to the true 
Salmonide helped the Acclimatization Society to argue that 
certain of our rivers would serve for the experiment of accli- 
matizing the European salmon and trout, and, as experience has 
since shown, successfully ; it is vulgarly also called the “ Yarra 
herring,” and is the Prototroctes marena. There is only one 
other fish known in Victoria with the second adipose dorsal fin 
and other characteristics of the Cuvierian Salmonide (but now 
referred to the Scopelide); it is the large and beautifully 
coloured marine form, the Awropus purpurisatus, of which I have
