BIRDS ‘OF NORTH AND MIDDLE AMERICA. 187 
Barnesia®? Bertoni, Aves Nuevas del Paraguay, 1901, 77. (Type, Synallaxis 
; cururuvt Bertoni=S. ruficapilla Vieillot.) : 
Small, wrenlike, long-tailed Furnariide (length about 130-150 
mm.) with only 10 rectrices, and with tail not more than one and a 
half times as long as wing. 
Bill much shorter than head, rather stout, moderately compressed, 
its width at loral antize about equal to its depth at same point and 
from one-third to one-half the distance from nostril to tip of maxilla; 
culmen gradually decurved from near base, the tip of maxilla not 
uncinate; tomia slightly decurved terminally, without trace of sub- 
terminal notch; gonys nearly straight, ascending terminally, at base 
forming a slight angle with lower edge of mandibular rami. Nostril 
exposed, posteriorly in contact with loral feathering, narrow (a longi- 
tudinal slit), overhung by a broad operculum. Rictal bristles want- 
ing, and feathers of chin, etc., without terminal sete. Wing rather 
short, very concave beneath, much rounded, the longer primaries 
exceeding secondaries by less (usually very much less) than length 
of exposed culmen; sixth and seventh, fifth, sixth, and seventh, or 
sixth, seventh, and eighth, primaries longest, the tenth (outermost) 
about two-thirds as long as the longest, the ninth shorter than sec- 
ondaries (S. pudica, S. erythrothorax) or very much longer (8. rufica- 
pilla, S. albescens). Tail decidedly longer than wing to nearly one 
and a half times as long, graduated for more than half its length, the 
rectrices (10) usually acuminate, sometimes with webs thin or semi- 
decomposed. Tarsus nearly to much more than twice as long as bill 
from nostril, nearly to quite three-fifths as long as wing, stout, dis- 
tinctly scutellate; middle toe, with claw, very slightly to decidedly 
shorter than tarsus; outer toe, without claw, reaching to slightly 
beyond subterminal articulation of middle toe, the inner toe very 
slightly shorter; hallux about as long as inner toe, but much stouter; 
basal phalanx of middle toe united for a little more than basal half 
to outer toe, for slightly less to inner toe; claws moderate in size and 
curvature, acute, that of the hallux much shorter than the digit. 
Coloration.—Color partly cinnamon-rufous, this either on pileum, 
wings, or tail, sometimes on all three, occasionally on chest; other- 
wise plain olive, brown, gray, or sooty, usually paler (sometimes 
partly whitish) on under parts; no streaks, spots, nor bars. Sexes 
alike. : 
Nidification—Nest an extremely bulky retort-shaped structure 
composed outwardly of coarse sticks, built in bushes or low trees; 
eggs white, bluish-white, or pale bluish green. 
@ Named for Carlos St, Barnes. (Bertoni.)
