264 NELSON, Wew North American Birds. fay 
General notes. —'This form is most readily distinguished from 
E. bairdi by the generally paler color and the much greater 
extension of the yellow on under parts, the broad area of olive 
green on the sides of the neck and across the breast being much 
more restricted and with a more brownish shade. 
In 1897 I described Ampidonax bairdi occidentalis (Auk, XIV, 
p. 53) and the name was intended to apply to the present form 
but by an unfortunate slip the specimen chosen and designated 
as the type, in the light of further material, proves to be strictly 
referable to &. bairdi and it consequently becomes necessary to 
choose a new type and redescribe the subspecies. The error 
came about through the fact that both &. dairdi and £. b. occi- 
dentalis occur in winter at Pluma, Oaxaca, the type locality for 
the last named bird, and are represented in our collection from 
that point. Nearly typical #. dairdi also occurs in winter in 
western Durango (Chacala) but we took only specimens of 
EL. b. perplexus between these two points.
