BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 293 



at Las Palmas, Chaco, on July 10, 1920, when an adult male was 

 secured. 



At the Riacho Pilaga, Formosa, two were taken (a female and one 

 other put in alcohol) on August 14, and others were seen. On the 

 Sierra San Xavier near Tafi Vie jo, Tucuman, they were fairly 

 common on the open slopes just above the forest on April 17, 1921, 

 and a female was secured. In the region of the Chaco the species 

 was found in heavy saw grass near the borders of low thickets. The 

 birds flew or climbed into the bushes where they worked away to 

 safety or remained at rest, often giving a curious tilting jerk to 

 the tail. They seemed to feed mainly on the ground. Above Tafi 

 Vie jo they clambered slowly about among dense growths of weeds. 

 The call note was a rapid chit tuck.

 guay.) 



A female, July 13 and a male July 14, 1920, shot near Las Palmas, 

 Chaco, were the only ones seen. The birds were encountered in heavy 

 forest near a stream, where they worked through the tops of the 

 trees in search of insects, in movement suggesting vireos, as they 

 frequently flew to a perch and remained for several seconds while 

 peering about. A large insect was beaten heavily on a limb. The 

 female uttered a low note that may be rendered as preer. The male, 

 when first killed, had the bill clear green-blue gray, except the tip 

 of the maxilla which was dusky ; tarsus and toes deep glaucous gi'ay ; 

 iris dull brown. 



The two taken are similar to a specimen from Sapucay, Paraguay, 

 and agree with it in being larger than P. v. cuvierii from Bahia. 

 The wing measurement of the skins from Las Palmas is as follows : 

 Male, 80.4 mm. ; female, 76 mm.

The only one observed was an adult male that was shot January 

 31, 1921, near San Vicente, Uruguay, in a small tract of low forest 

 near the Laguna Castillos, where the bird perched like a flycatcher 

 on a dead limb in a small, well-shaded opening among the trees. 

 This specimen, with a wing measurement of 86.5 mm., presents in a
