9. Central America and Mexico. 

 Total number of Guiana birds found in 



Central America and Mexico ... 196 



Less migrants 27 



sea-birds 6 



— 33 



163 



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 liaA^e 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. 

 Total number of Guiana birds found in the 



West Indies . 52 



Less migrants 23 



sea-birds 6 



— 29 



23 



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. 



11. North America. 

 Total number of Guiana birds found in 



North America 61 



Less migrants 29 



sea-birds 5 



or about 4^ per cent, of the 589 Guiana birds.
