As was pointed outin the introductory article of this volume, a certain numberof writers maintain that this Region does not contain asufficient quantity of distinctive and indigenous forms toentitle it to separation from the Palsearctic Region. Whatshould constitute a sufficient number of distinctive formsdepends, of course, largely on the individual opinions ofthe writers, but if allowance be made for the undoubtedsimilarities of the extreme northern parts of the Old andNew Worlds, which together may be considered as form-ing a kind of intermediate district, the facts and figuresgiven below will, we think, convince every one that theland-surfaces of the Palrear
