greater length of the feathers ; outer pair of rectrices broadly barred 

 with white for at least the terminal half (sometimes the whole length), 

 and next pair with several broad bars across the terminal portion. 

 Adult 5 : Similar to the (? , but without the red crown patch. Wing, 

 5.00-5.30 ; tail, 3.50-3.90 ; cnlmen, .95-1.25 ; tarsus, .90-.95. 



This is the only species of the genus in which the female has neither 

 red nor yellow anywhere about the head or neclc, and in which the lat- 

 eral tail-feathers are banded for the greater part of their length, and the 

 upper tail-coverts transversely barred. 



Among thirteen adult males now before me I find considerable varia- 

 tion, which, however, affects chiefly the color of the nape, the exact 

 shade of color jiervading the head and lower parts, and the size and 

 shape of the red crown-spot. In two specimens (7G735, Fort Yuma, 

 Dr. A. L. Heermann, and 49G8.'), Camp Grant, Arizona, March 20, 

 18G7, Dr. E. Palmer), the nape inclines very strongly to a light ful- 

 vous-bnff, strikingly different in color from the occiput, sides of the 

 crown, etc. Usually the nape is similar in tint to the breast, but of a 

 decidedly darker shade, this being j)articularly the rule in fall speci- 

 mens, in which the colors are darker and the texture of the feathers 

 softer than in spring and summer. The exact tint varies greatly, how- 

 ever, the darkest example (No. G7153, Pueblo Viejo, New Mexico, Sep- 

 tember 19, 1873, C. J. Newberry), having the najie a deep sepia-drab, 

 while in the lightest (No. G129, Camp Yuma, California, A. Schott), ic 

 is a light ochraceous-buff, the lower i^arts being also much paler than 

 usual. Summer specimens, having the plumage more worn and bleached 

 than those killed in the fall or winter, are of course i)aler colored. The 

 exact shape and extent of the red crown-patch vary greatly in differ- 

 ent examples, but this may be owing in a great measure to the "make" 

 of the skin.
