reland as well as the whole of Scotland
the other. His classification is of particular interest, since the first
district represents part of a larger Atlantic province, the second a
portion of the Germanic province of the European sub-region. The latter
he looks upon as one of the sub-regions of the great Palaearctic Region.
Attention is thus drawn to the intimate relationship existing between
the western parts of the British Islands and the Spanish peninsula on
the one hand, and between the eastern portions and Central Europe on the
other.

Mr. Jordan's North-Sea-and-Baltic district includes Scotland and the
North of Ireland, whilst England joined with the West and South of
Ireland forms part of his Celtic province. Both of these districts or
provinces belong to Mr. Jordan's greater Germanic Region (p. 302).

In the collection illustrating the geographical distribution of animals
in the Dublin Museum, the British species have been grouped into three
divisions. One contains those with a wide range over the British
Islands, another the characteristic forms of the south-east and lowland
districts of Great Britain, and the third the Irish and the western and
highland Anglo-Scotian species. Mr. Carpenter has named the last two
divisions the "_Teutonic_" and the "_Celtic_." More recently, he has
recognised that this last division contains two distinct groups; one
including animals of northern, the other those of southern origin. He
acknowledges indeed, just as I do, three distinct faunas in the British
Islands, with the addition of the group of generally distributed species
of undetermined origin.

Many other naturalists have worked in the direction I have
indicated--namely, in grouping the British animals into several distinct
assemblages, without, however, taking their foreign range into
consideration, or their origin. I have already referred to the useful
work done by botanists, who have been the pioneers in the science of the
geographical distribution of living organisms. Among the British
naturalists who have applied the principles of Watson to zoology, A. G.
More deserves to be specially mentioned. He was the first to make a
serious study of the British fauna on the lines laid down by that
distinguished botanist. In conjunction with E. Boyd, he published a
valuable essay on the "Distribution of Butterflies in Great Britain,"
and later on the birds were similarly dealt with. All the more
important groups of animals a
