74. PETNLEA. 7U 



Of the value of this race I cannot form an effective judgment, as 

 I have only seen one specimen, and that one in bad condition. ' It 

 is probable that P. arizonce is only a pale form of P. aestivalis or 

 P. bachmani.

Adult (type of species). Similar to P. aestivalis, of which it is a 

 large form. Total length 6 inches, culmen 0-5, wing 2-6, tail 2-55, 

 tarsus 0-85. 



There is considerable difference between the breeding and winter 

 plumages in this species. As the plumage becomes worn, nearly all 

 the grey of the upper surface disappears, leaving the mesial black 

 of the feathers predominant, with a good deal of the chestnut. In 

 winter the rufous edges of the secondaries are very distinct, and the 

 inner secondaries are fringed with rufous at the ends. This latter 

 edging becomes grey in the summer. 



Similar changes of plumage are undergone by the other races of 

 P. aestivalis, and it is necessary for correct comparison that speci- 

 mens killed at similar seasons of the year should be examined. 



Young. More mottled than the adults, the feathers being dusky 

 brown, with sandy-buff margins ; on the scapulars and inner secon- 

 daries the margins are more chestnut ; lores tinged with yellow ; 

 under surface of body more fulvescent than the adults, with brown 

 spots on the sides of the fore neck.
