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 measure- 

 ments 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
