(No. 33,265.) First primary very nearly half the third. Tarsus and middle 

 toe about equal. Above reddish-brown, with a tinge of olivaceous ; very 

 obsoletely banded with dusky ; a little brighter on the rump. Wing and tail 

 very dark-brown, banded with the color of the back, the black bands rather 

 the narrower ; dusky bands rather more conspicuous on upper tail coverts. 

 An obscure line over eye and the under parts brownish-fulvous, paler on 

 throat and middle of belly, darker on sides ; entirely free from bars, except the 

 faintest possible indication on the side of the anal region. Crissum similar, 

 with distinct black bars ; the light interspaces whitish in spots. Bill dusky, 

 yellowish at base below. 



Total length of the dried specimen, 4.50; wing, 2.00; tail, 1.72; gradua- 

 tion, .35 ; exposed portion of 1st primary, .74, of 2d, 1.26, of 3d, 1.48, of 

 longest (measured from exposed base of 1st primary), 1.50; length of bill 

 from forehead, .62, from nostril, .40, along gape, .71 ; tarsus, .73 ; middle toe 

 and claw, .69 ; hind toe and claw, .55 ; claw alone, .25. 



A type specimen of hyp^don, labelled by Dr. Sclater, and received from M. 

 Salle, agrees in general appearance witli the Costa Rican bird, but the bill is 

 stouter and plumbeous below. The color generally is lighter ; the quills paler, 

 and their inner edges instead of being ashy, are grayish-white. The wings 

 are shorter. 



This species may be easily distinguished from T. sedon, and all other 

 more northern allies, by the decided fulvous tinge of the under parts, 

 and the almost entire absence of bars on the flanks or under parts, 

 excepting crissum. .The upper parts are more faintly barred. The 

 quills and tail feathers are much darker, without the whitish spotting 

 on outer edge of former ; the dark bars on tail more numerous, and 

 nearly as wide as their interspaces, instead of half the width, etc. 

 From most of the smaller South American "Wrens, which closely 

 resemble this species in color, it differs in the more decidedly barred 

 crissum, more numerous dark bars on tail, etc.
