As in lleodes also, its immediate relatives are found in ^reatei aliundaiici' in the Old ^^'orld than in the New: Imt on the other hand the develop- ment of \arietal forms within the sp<'<'ies is so^jreatly in excess in Ameri<'H, hat we nuist conclude it prohahie that its life on this contitu'nt has hecn lon;rer than on the ()ld.
