ro08 THE EDIBLE FISHES OF NEW SOUTH WALES. 
pointed’ at the tail end, and is well-named “ tongue”’ fish. 
The upper part of the snout is produced backwards over the 
mouth, into a long hook-shaped flap, known as the ‘“‘ rostral 
hook.”” The eyes are on the left side. 
The color is a pale yellowish-brown, with numerous 
round spots of a creamy tint. 
In capturing the Tongue-Fish, it is necessary to have a 
net which is so arranged as to “bite” the bottom well, 
owing to the habit of this species of clinging so close to the 
sand. 
THE RED ROCK COD FAMILY. 
Red Gurnet Perch (Sebastapistes percoides). 
This is a rock-frequenting fish usually obtained by hook 
and line in the vicinity of reefs at sea. It enters but little 
into the food-supply of New South Wales, as it only appears

Perch is exceedingly beautiful in coloration. 
It attains exceptionally a length of about 12 inches. 
Thetis-Fish (Sebastodes thetidis). 
This name has been given to a fish, allied to the preceding, 
which was first captured during the trawling of Mr. Farnell’s 
“Thetis”? Trawling Expedition in 1898. As it may prove 
later to be of some importance, I have included it in this list. 
It was obtained on four occasions by the “ Thetis,” in depths 
ranging from 55 to 78 fathoms, and up to a length of about 
12 inches. 
Red Rock Cod (Scorpena cruenta). 
PLrateE LXXV. 
Under the name of Red Rock Cod are commonly included 
two species, that mentioned above, and an allied form known 
as Scorpena cardinalis. As the latter is rather rare, it is
