DESCRIPTION OF A NEW SUBSPECIES OF MELEZA-— 
GRIS GALLOPAVO AND PROPOSED CHANGES 
IN THE NOMENCLATURE OF CERTAIN 
NORTH AMERICAN BIRDS. 
BY E. W. NELSON. 
WHILE working on the Mexican birds in the Biological Survey 
collection, the necessity of certain changes in the nomenclature 
of several North American species has become evident. These 
changes refer to AZeleagris gallopavo, Colaptes cafer, Sayornis nigri- 
cans, Myiozetetes texensis, and Agelaius phaniceus longirostris. The 
most interesting development of our recent work is the demon- 
stration of the difference between the Wild Turkeys of Arizona 
and those of the Sierra Madre of western Mexico as detailed 
below. 
All measurements are given in millimeters.
