Auriparus Baird, Review Am. Birds, Aug., 1864, 85. (Type, JEgithalus flamceps 

 Sundevall. ) 



Very small Paridse, with conical, acute bill; the outermost (tenth) 

 primary much less than half as long as ninth; plumage without any 

 black, but adults with head partly yellow and lesser wing-coverts 

 bright reddish chestnut. 



Bill much shorter than head (exposed culmen about half as long as 

 tarsus, but shorter than middle toe without claw), with nearly straight 

 outlines and acute tip; culmen very faintly curved terminally. Nos- 

 trils as in Bseolojphus and Penthestes, but antrorse latero-frontal feath- 

 ers less produced. , Rictal bristles obsolete. Wing rather long, but 

 rounded; eighth, seventh, and sixth primaries longest, usually the 

 eighth;, ninth primary equal to or longer than fourth, much more than 

 twice (nearly three times) as long as tenth, which is very small and 

 narrow. Tail nearly as long as wing, slightly rounded. Tarsus about 

 twice as long as exposed culmen, decidedly longer, than middle toe with 

 claw, less than one-third as long as wing, the acrotarsium distinctly 

 scutellate; outer toe slightly longer than inner, its claw reaching about 

 to base of middle claw; hallux (without claw) about as long as inner 

 toe (without claw), but stouter, its claw much shorter than the digit;
