��K 1* that late epoch of the earth^s history which immediately preceded '^^ "the development of continental ice sheets, or the Pleistocene ffiei^l period in North America and Europe, we find but little evidence of wlia.t the next few thousand of years had in store for the rich ter- ^^al faunas and floras that had spread from Gibraltar to Korea and pro Dat>ly across the Bering land bridge between Asia and America, and OYeT a part of the latter continent.
The Pliocene age, as the era immediately preceding the Glacial period
^ termed, probably witnessed the most profuse and diversified mam-
^^lian life and arborescent flora that the world has ever seen. The
- ^Una, sometimes known as the Hipparion fauna, from the abundance
^t that time of the small fleet horses of the Hipparion type, is somewhat
- ^tteT known than the flora for the whole eurasian area, although for
ti^e area of Europe the flora is very well represented at a large number
of localities. The fauna as shown by the accompanying sketch map
(Fig. 1) has been traced from the Tagus Valley on the west to Korea
