Mr. Stone and Dr. Merriam, and those associated with them in the 
work.! 
A subcommittee on the revision of the vernacular names consisted 
of the Chairman and Dr. Dwight. The changes made are not numer- 
ous, and are mainly the substitution of the vernacular names most in 
use within the range of the species. (For a list of these changes see 
the Fifteenth Supplement, published in ‘The Auk,’ July, 1909, pp. 302, 
303). 
The final editorial supervision of the new Check-List was assigned 
to the Chairman.
