on the upper wing coverts smaller and tawnier ; tarsi longer and much 

 more scantily feathered ; the feathers much shorter and never extending 

 down to the base of the toes, even in front, the posterior side of the tarsus 

 always (even in winter) with a broad exposed naked strip (much the 

 greater part of the tarsus naked in summer). From the nominate form 

 this race differs in lacking the conspicuous pale terminal spots on the 

 scapulars, in having the pinnae composed of more than 10 feathers which 

 are abruptly truncated and not pointed, and in having the ventral bars 

 somewhat narrower (but nearer to T. c. cupido than to T. c. p'mnatiis 

 in this respect) and considerably paler — drab to pale buffy brown, and 

 in having the upper breast washed with cinnamon to cinnamon-rufous. 



Juvenal. — None seen. 



Dozvny young. — Not certainly distinguishable from that of T. c. pin- 

 natus but apparently very slightly darker in its general tone above.
