Nors. — As authority for names of species in this work, the original 
describer of the species is alone given. The name is written in full 
except in case of Linnzus, 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 Linneus placed his 
species corax in Corvus, where it still remains. 
“ Melanerpes erythrocephalus (1.),” indicates that the species (Picus 
erythrocephalus of Linnzus) 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.
