or about 27\ per cent, of the 589 Guiana birds. 
These 163 Central-American birds are almost all found 
in the intermediate countries, Venezuela, or Colombia, so 
that Guiana can hardly be said to have any special relation¬ 
ship to Central America. The only point that occurs to me 
in this connection is the affinity of the newly described Euco- 
metis oleaginea to E. cassini, a bird of Southern Central 
America and the northern part of Colombia, no allied species 
being found in the intermediate country. 
10. West Indies.

West Indies. 52 
Less migrants. 23

— 29

or about 4 per cent, of the 589 Guiana birds. 
As there are no species common to the West Indies and 
Guiana exclusively, this small percentage of common resident 
species of wide range shows that the connection between 
Guiana and the West Indies is very slight indeed.
