Diagnosis. — Ground-color above pale gray or gray isb -brown, relieved 

 by the usual ragged mesial streaks of black, and irregular mottliugs 

 and vermiculations of lighter and darker shades. The groundcolor, how- 

 ever, never inclining strongly to reddish, and not darker in shade than 

 a very light ash-gray or brown. The white spots on outer webs of the 

 primaries frequently confluent, the darker spots, in extreme cases, being 

 hardly visible on the basal portion of the quills when the wing is closed. 

 Face grayish-white, with faint vermiculations of darker grayish. No 

 rusty gular collar, but in its stead sparse, narrow bars of brown or 

 rusty on a white ground. Wing, G.80-6.90; tail, 3.90-4.10; culmen, .60; 

 tarsus, 1.45-1.50; middle toe, .80-.85. 



The characteristics of this form are remarkably constant, a series of 

 a dozen or more specimens affording no instance of notable variation.
