The species of all kinds which inhabit oceanic islands are few in number compared with those on equal continental areas: Alph. de Candolle admits this for plants, and Wollaston for insects. →OMIT New Zealand, →for instance, with its lofty mountains and diversified stations, extending over 780 miles of latitude, →together with the outlying islands of Auckland, Campbell, and Chatham, contain altogether only 960 kinds of flowering
