BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 295
near the Rio Paraguay at Puerto Pinasco, Paraguay, on September
3, so that both are assumed to represent the typical form, which
would seem then to range south through the Chaco of northern
Argentina, A female in the Page collection, taken at Parana, has
the underparts browner and the bill larger than the female from
Puerto Pinasco, and is supposed to be H. f. minimus (Gould). ®^
Habrura hogotensis Chapman,'" of which there is an adult male,
taken by Hermano Apolinar Maria at the type-locality, in the United
States National Museum, differs from 'pectoralis in much more ru-
fescent coloration and in Avholly black bill, so that it seems to repre-
sent a distinct species.
On the two occasions that I encountered this tiny bird, it was
found among weeds and low bushes in pastures not far distant from
water. The few individuals seen, rather wild and difficult to ap-
proach, fluttered about a few inches from the ground until flushed,
when they flew with a rapid, quickly undulating flight to low perches
on the sides or tops of small weeds. When at rest they occasionally
twitched the tail quickly. In general appearance and mannerisms
they suggested small flycatchers.
Mr. Ridgway '^ considers this bird out of place in the Tyrannidae
and suggests that it may be better located among the Cotingas.

Three specimens of this large species, all in full winter plumage,
were secured at Concon, Chile, a male on April 24, 1921, and females
on April 25 and 28. Wing measurements of these three are as fol-
lows: Male, 131.5 mm.; females, 124 and 124.5 mm. Agriornis I.
fortis Berlepsch "^ is distinguished by larger size and paler colora-
tion. Two skins of fortis secured from E. Budin, taken April 17
and 27, 1918, at Puesto Burro, Maiten, Chubut, have wing measurements
of 144.6 (male) and 134.5 mm. (female). Two immature
birds (U. S. National Museum coll.), secured February 24, 1897, at the
head of the Rio Chico, Santa Cruz, and March 7, 1897, on the Pacific
slope of the Cordillera, beyond the locality first mentioned, have the
head, back, and upper breast indistinctly streaked with dusky, but
