Hab. Costa Rica, Guatemala, and southern Mexico (Oaxaca, Sci.). 
(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 lst primary, .74, of 2d, 1.26, of 3d, 1.48, of. 
longest (measured from exposed base of Ist 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 hypzxdon, labelled by Dr. Sclater, and received from M. 
Sallé, agrees in general appearance with 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 7. edon, 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, ete. 
From most of the smaller South American Wrens, which closely 
resemble this species in color, it differs in the more decidedly barred 
erissum, more numerous dark bars on tail, etc.
