192 Prof. M‘Coy on the Recent Zoology 
or Phocodon (P. Wilkinsoni, M‘Coy), from the Miocene Tertiary 
sands of the Cape Otway coast: and as the genus is only known 
in Miocene strata of Malta and the French falun, the occurrence 
of a new species of so restricted a genus is not only valuable as 
an addition to paleontology, but an interesting fact as showing 
that the zoology of Australia, as I have on former oceasions en- 
deavoured (contrary to received opinions) to establish, was not, 
during the older Tertiary period, of the isolated exceptional 
character it now has, but was then closely related generically, and 
even specifically, as [ shall show, to that of many parts of Europe 
and America. The molar teeth of P. Wilkinsoni are smaller 
than the Maltese P. scille, and agree most nearly with the Squa- 
lodon (Phacodon) Grateloupi (Meyer) of the Miocene beds near 
Bordeaux, from which the Australian species differs chiefly in 
smaller size, some details of proportions, and the relatively 
larger roots, indicating a greater depth of jaw. In these same 
beds remains of fish are not uncommon; and these are almost 
all of well-known European and American Miocene and Upper 
Kocene Tertiary extinct species of Plagiostomi: the most 
abundant widely distributed species is, I have no doubt, per- 
fectly identical with the Carcharodon angustidens (Ag.) of the 
Biinde and other well-marked European Lower Miocene and 
Oligocene beds. The C. megalodon (Ag.) is an almost equally 
common Australian Miocene species, and (on comparison, as in 
the former case, of specimens) undoubtedly identical with the 
‘ Lower Miocene and Oligocene Tertiary specimens from Malta, 
Biinde, and other European sections, and with those from the 
Eocene London Clay and North-American localities. The 
Otodus Desori (Ag.), Lamna elegans (Ag.), and L. contortidens 
(Ag.), of the European and United-States Miocene localities, 
are also common in many of our Victorian Miocene beds, in 
which I have also identified the Zamna denticulata (Ag.), and 
the large teeth of Oxyrhina trigonodon (Ag.), exactly agreeing 
with those of the Lower Miocene beds of the Rhine country. 
Along with these entirely extinct plants, mammals, and fish, 
there are many genera and species of Mollusca entirely extinct, 
many identical with extinct species of the same geological age 
in other localities both in Europe and North America, and many 
of the commonest forms are identical with living species, none 
of which are found in the adjacent seas of Victoria, but in the 
warmer seas north of New Zealand, Philippines, and South 
Africa), with one or two rare exceptions of species extending 
into colder latitudes in the northern hemisphere. 
A fine new Aturia (A. australis, M‘Coy) is the most common 
and important of the fossil Cephalopoda, closely related to the 
Aturia ziczac of the Lower Miocene and Upper Eocence beds
