12 NEW SOUTH WALES 
The following genera are peculiar to the South Australian region, 
though some, here marked in italics, extend to the coasts of New South 
Wales :—Trygonorhina, Enoplosus, Lanioperca Arripis, Tephreops, 
Trachichthys, Chironemus, Holoxenus, Nemadactylus, Latris, Glyp- 
tauchen, Pentaroge, Anema, Craptolus, Kathetostoma, Leptoscopus, 
Platystethus Brachionichthys, Saccarius, Lepidoblennius, Pateecus, 
Acanthoclinus, Diplocrepis, Crepidogaster, Trachelochismus N eophry- 
nichthys, Labrichthys, Oda, Coridodax, Olistherops, Siphonognathus, 
Pseudophycis, Lophonectes* Brachypleura, Ammotretis, Rhombosolea, 
Peltorhamphus, Teratorhombus, Rhomboidichthys, Chilobranchus, Nanno- 
campus, Stigmatophora, Phyllopteryx. 
Thus out of 44 genera, which are, as far as known, peculiar to the 
southern portions of the Australian region, New South Wales possesses 
only 18 of these, numbering in all 23 species. 
Of these eighteen genera eight extend to N. Zealand, and one, 
Trachichthys, is found only there and in Tasmania, and one (Leptoscopus) 
has three species in N. Zealand to our one. 
The following genera of the equatorial or tropical zone are found on 
the coasts of N. S. Wales:—Anthias 1, Serranus 4, Plectropoma 4, 
Apogon 2, Gerres 3, Pentapus 2, Chrysophrys 2, Platycephalus 3, 
Lethrinus 3, Trigla 3, Sillago 2, Sciena 1, Sphyrena 2, Caranx 4, 
Psettus 1, Teuthis 2, Pempheris 2, Callionymus 3, Batrachus 1, 
‘Petroscirtes 5, Fistutaria 1, Pomacentrus 1, Heliastes 1, Synaptura 2, 
Elops 1, Chanos 1, Chirocentrus 1, Murenesox 1, Murena 1, Hippo- 
campus 1, Monocanthus 17, Ostracion 4, Tetrodon 10, Diodon 4, 
Carcharias 3, Zygena 1, Wotidanus 1, Chiloscyllium 1, Urolophus. 
All the above thirty genera, including more than 100 species, are. 
characteristic of the tropics, and seldom seen outside the equatorial 
zone. There are twenty of the same genera marked in italics which 
are best represented in the tropics. Thus more than one fourth of the 
fishes found on the coasts of N. 8. Wales are tropical. We have only 
at the most about five and twenty of the exclusively Australian fishes. 
The rest of our fish fauna is made up of fishes wide in their distribution, 
or which are restricted to one or two other provinces or peculiar to our 
coasts. From 160 to 170 species have been found in no other parts of 
Australia-but on the coasts of New South Wales; but no accurate 
conclusion can be drawn from this, as our coasts have been so very much 
better searched than those of any other Colony, and there are very many 
and very extensive parts of the Australian coast line which have never 
been searched at all. Thus, for instance, we know nothing of the fish 
fauna of the coast between Adelaide and King George’s Sound, and of 
the north coast Port Darwin has been the only portion searched, and 
that far from thoroughly. In a journey I made to the head of the 
Mitchell I found in some of the tributaries three new species of fresh- 
water fish, including a Synaptura or sole. This will show what there is 
still to be done in the watershed of Carpentaria. 
‘A good many of the 160 species mentioned above are Indian fishes,— 
that is found on the Indian Archipelago or on the coasts of the Indian Ocean. 
It may therefore be fairly inferred that, if they are found on the coasts 
of N. 8. Wales, they will also be found on the intervening shores of North 
and North-east Australia when they are searched.
