Thus, " i. x-f " indicates two incisor teeth on each side in the upper 

 jaw, and one on each side in the lower. 



" Toes 5-4 " implies fore feet five-toed, hind feet four-toed. 



Note. — As authority for names of species in this work, the original 

 describer of tlie species is alone given. The name is written in full 

 except in case of Linnajus, abbreviated as " L." 



In case the original combination of general and specific name is 

 still retained, the name of the author is printed without parentheses. 

 In case, however, the original describer placed the species in question 

 in a genus different from the one here adopted, the author's name is 

 enclosed in parentheses. 



Thus (page 277), " Corvus corax L." means that Linnjeus placed his 

 species corax in Corvus, where it still remains. 



" Melanerpes erythrocephalus (L. )," indicates that the species {Picus 

 erythrocephalus of Linnajus) is now placed in a genus different from 

 the one in which it originally stood. Melanerpes is a modern subdi- 

 vision of Picus, which formerly included all Woodpeckers. 



" Eu." indicates that the species in question is also found in Europe.
