and has been formally adopted by the legislature of Louisiana in 
selecting Audubon’s birthday as the date for the celebration of Bird 
Day. 
Further investigation is necessary to settle the various points still 
in doubt and to complete the comparatively meager data on which 
the list is based. As it stands the list contains the names of about 
275 persons, many of whom have been prominent in ornithology in 
the last half century. 
SUPPLEMENTARY LIST. 
In the general Index about 175 authors’ names appeared in more 
or less incomplete form. Some of the missing names came to 
light in the course of the present work and it seemed desirable to 
complete as many of them as possible before it was too late to collect 
the information. As a result of the combined labors of the com- 
mittee and their correspondents, 145 names have been found. Of 
the 30 still missing, about one-fourth are foreign and the others 
with possibly three or four exceptions are of minor importance from 
an ornithological standpoint. 
ACKNOWLEDGMENTS 
One of the features of an undertaking of this kind which goes far 
toward lightening the routine labor is the cordial spirit of coopera- 
tion and the ready response to calls for aid manifested on all sides. 
Without such assistance it would often be impossible to collect the 
widely scattered information but with it the labors of the committee 
are greatly lightened and the work becomes a cooperative one to 
which a large number of persons contribute. 
Responses from members of the Union have been prompt and gen- 
erous and among those who have rendered valuable assistance are the
