It is a remarkable fact that so many of the species belong to genera which are
wholly Neotropical, and that the specially South American families of Icteridae,

We have already suggested an explanation of this fact in the case of the
Carabidae, and with the butterflies it is not more difficult. The great mass of
Neotropical butterflies are forest species, and have been developed for countless

They consist of two very large islands, Cuba and
Page 552 - catalogued on a uniform plan, and with a uniform nomenclature, a thoroughly satisfactory account of the Geographical Distribution of Animals will not be possible. But more than this is wanted. Many of the most curious relations between animal forms and their habitats, are entirely unnoticed, owing to the productions of the same locality
