All the genera that are of any importance or have an economical value 
are described at sufficient length in the next chapter ; but in the foregoing 
list there are a few genera which are represented in Australia by a great 
number of species. They are not important as articles of food, but as 
they are so numerous in our seas, and therefore become characteristic 
of our fish fauna, a more extended notice of them is desirable. Some 
remarks will also be added on a few of the remarkable and exceptional 
fishes which are found-on the coasts of New South Wales. 
Frog-fish. 
Or Antennarius belonging to the order of Pediculati, a name which 
expresses the singular foot-like office of the fins, which are more fitted for 
walking along the bottom than for swimming. To this order belongs 
Lophius piscatorius or Fishing Frog so well known all over the world. 
The genus Antennarius, of which we have many species in Australia, is 
distinguished by a very large head and frog-like body without scales, with 
. a, peculiar tentacle just above the snout. The species are pelagic, mostly 
tropical, and found crawling on floating sea-weed in mid-ocean. They 
cannot swim much, so on the coast conceal themselves amid the stones 
and sea-weed, holding on by their arm-like fins. They are all highly 
coloured, yet their hues are assimilated to the surrounding medium, so 
that it is very difficult to distinguish them in the water. All the species 
have a wide range, and this arises from their living in the open ocean, 
attached to sea-weed, whence they may be drifted anywhere. As their 
colour depends much on the medium where they are found, no doubt a 
good many different names have been applied to the same fish by 
naturalists, This is the case with our common 4. marmoratus, Less., 
which has a vocabulary of synonyms all to itself, Probably some of our 
many specific distinctions will be reduced hereafter to two or three forms.
