Troglodytes aedon Vieillot. ) ^ 



Small Troglodytidae (wing 46-60 mm.) resembling Thryomanes in 

 having the hallux (without claw) not^ longer than outer toe (without 

 claw), but in other characters more like Thryothorus. 



Bill much shorter to a little longer than head, straight (or at 

 least with only the tip verj^ faintly decurved), gradually tapering, 

 compressed anterior to nostrils, its depth at latero-frontal antise equal 

 to or (usually) greater than its width at same point; exposed culmen 

 usually longer than middle toe without claw (shorter only in T. aedon), 

 straight basally (usually for most of its length), gradually and not ver}' 

 sti'ongly decurved terminally; gonys decidedly shorter than distance 

 from nostril to tip of maxilla, straight, its base usually forming a dis- 

 tinct, though slight, angle; maxillary tomium faintly concave anterior 

 to nostril, without trace of subterminal notch. Nostril longitudinal, 

 cuneate or guttate (pointed anteriorly), overhung by a distinct excur- 

 rent corneous operculum, posteriorly in contact with feathering of 

 latero-frontal antise. Eictal bristles obsolete. Wing moderate, 

 rounded; seventh and sixth (or eighth to fifth) primaries longest, the 

 eighth and fifth never much shorter than seventh and sixth; ninth 

 primary usually equal to or slightly longer than first (slightly shorter in 

 T. hrunneicoUis), the tenth half as long as ninth or a little more. Tail 

 two-thirds to more than five-sixths as long as wing, much rounded or 

 graduated, the rectrices rather narrow, with rounded tip. Tarsus 

 longer than middle toe with claw, less than one-third to considerably 

 moi'e than one-third as long as wing, the acrotarsium distinctlj^ scutel-
