Although in oceanic islands the →number of kinds of inhabitants is scanty, →the proportion of endemic

endemic birds in the Galapagos Archipelago, with the number found on any continent, and then compare the area of the

with that of the continent, we shall see that this is true. This fact might have been →expected on my theory, for, as already explained, species occasionally arriving after long intervals →in a new and isolated district, and having to compete with new associates,
