therefore, much of the matter contained in the general portion of 
the bulletin is to be found in substance in the writings of others, 
there is also a considerable part of this which summarizes the re¬ 
sults of original observation.

one species have been added to the preliminary Oberholser list, class¬ 
ified as follows:

Practically all of these were identified in life with a ,prisn

dead specimens came was in every case established by an interview 
with the parties who shot them. Hoyt’s Horned Lark was admitted 
*We have not included in this list a somewhat uncertain record of the Yellow-throated Warbler. 
What certainly appeared to be this species was observed by the junior author in an orchard north of 
Wooster, May 13, 1902. The examination was made through a binocular glass at a distance not to 
exceed 20 feet. While the observer was quite certain of the identification, it has not been included in 
the list since the skin was not secured.
