several mountain-ranges and on the arctic lands of
→the two Worlds. Hence it has come, that when we compare the now living productions of the temperate regions of the New and Old Worlds, we find very few identical species (though Asa Gray has lately shown that more plants are identical than was formerly supposed), but we find in every great class many forms, which some naturalists rank as geographical races, and others as distinct species; and a host of closely allied or representative forms which are ranked by all naturalists as specifically distinct. |

| As on the land, so in the waters of the sea, a slow southern migration of a marine fauna,
during the Pliocene or even a somewhat earlier period, was nearly uniform along the continuous shores of the Polar Circle, will account, on the theory of modification, for many closely allied forms now living in
completely sundered. Thus, I think, we can understand the presence of
→many
existing and
→tertiary representative
on the eastern and western shores of temperate North America; and the still more striking
of many closely allied crustaceans (as described in
admirable work),
some fish and other marine animals,
the Mediterranean and
the seas of Japan,—

separated by

continent and by

| These cases of
→relationship, without identity, of the inhabitants of seas now disjoined, and likewise of the past and present inhabitants of the temperate lands
of North
→and
Europe, are inexplicable on the theory of creation. We cannot
that
have been created alike, in correspondence with the nearly similar physical conditions of the areas; for if we compare, for instance, certain parts of South America with
