356 BIRDS OF PALESTINE AND PANAMA COMPARED. 
thirty-seven are water birds, Natatores and aquatic Cursores, 
showing that it is not the ocean that yields the abundance — 
here. Of the 348 land birds, forty-four are characteristic 
of, or occur in North America, exclusive of Mexico, and 290 
are of South American kin. We need not then hesitate to — 
refer this region to the latter fauna, especially as we know 
many of the same species to be to some extent dwellers it 
Mexico. On this and other grounds we may safely add the 
thirty-six species which range from Mexico to the Isthmus 
as their ultima thule southward, to the evidence that this 
region is far within the frontiers of the Regio Neotropica. 
Eighty of the 348 are familiar rangers of Central Ameri, 
which have not spread farther towards the fields of the Mor 
tezumas; and those which find their kin limited to the Ist 
mus and adjoining regions of New Grenada, and Equador 
amount to about seventy-five more. Twenty-seven ie me 
number not known to extend beyond the boundaries of 
Palestine; as to the Middle. States of our Union, not 0 — 
species has been shown to be restricted within such narrow 
limits. 
A single species occurs in Europe; this is 
an animal which combines the cosmopolite ha 
bird with the powerful flight of the bird of prey: The® 
also the only species common to the Panama and Palestin? 
catalogues. 
The birds of prey are numerous— twenty-nine species 
Among these there is no true eagle or falcon, and “7 
nineteen genera, but four belong to the fauna of the Bow 
Land. There is but one species to represent the gres 
family, but instead, three families of their 
can imitators, the Pullastræ, instead of the one, ©"
