more marked than in the present form. Particuhirl}^ is this noticeable 
in the coU)r of the upper surface; for from the gray and pink tints of 
some specimens to the reddish and cinnamon shades of others, from 
the pallid appearance of some to the deep colors of others, there seems 
to be almost more latitude than can possibly be reconciled to the 
idea of subspecific identit}'^; yet such is undoubtedly the fact, as breed- 
in tr specimens from identical localities attest. Some incidental men- 
tion of these variations lias been made in the comparisons of actia with 
other forms. The 3'ellow of the head and throat is rarely of a deep 
shade, though this color is seldom entirely absent from the latter; but 
the e\'ebrow is frequently white. The thighs are sometimes tinged 
with 3^ellow. 
In all, 288 specimens of this form have been available, geographi-
