BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 411 



ern localities, and may be distinguished under the subspecific name of 

 araguira. Skins from Tapia, Tucuman, and Salta are somewhat 

 brighter than those from Chaco and Formosa, while specimens from 

 Sapucay and Puerto Pinasco, Paraguay, are distinctly intermediate 

 between the typical form and its southern representative, but are 

 placed best with araguira. The range of C. c. araguira may be given 

 as from Santa Fe and Corrientes north through Paraguay, west 

 apparently into Bolivia (one specimen seen marked "La Paz"). 



At Resistencia, Chaco, this finch was observed commonly from 

 July 8 to 10, 1920, and a fine male was collected July 8. At Las 

 Palmas, Chaco, a few were noted from July 16 to August 1, and at 

 the Riacho Pilaga, Formosa, a few were observed from August 13 

 to 18, and male and female were taken August 14. The species was 

 noted near Formosa, Formosa, on August 24, and at Kilometer 80, 

 west of Puerto Pinasco, it was recorded occasionally from September 

 7 to 15. On September 30 one was taken from a little flock at the 

 base of the Cerro Lorito on the eastern bank of the Rio Paraguay 

 opposite Puerto Pinasco. 



These handsome little birds were found in pairs or small bands in 

 low, heavy brush at the borders of fields or groves. They sometimes 

 fed like other finches on the ground among clumps of grasses, but 

 more frequently at an alarm appeared from the depths of thickets 

 to scold excitedly and perhaps to fly with an undulating flight for 

 a few yards to new cover. Sometimes they were encountered in 

 company with Poospiza meJanoleuca. The feathers of the eyelids 

 are clear white, so that at a little distance the eye appears large and 

 white. 



The Toba Indians in Formosa called this species koi yoh. 



A male, taken July 8, had the maxilla dusky black ; tip of mandible 

 dull slaty black ; base pallid purplish gray ; iris Army brown ; tarsus 

 and feet dusky brown. 



BRACHYSPIZA CAPENSIS CAPENSIS (P. L. S. Miiller) 



Fringilla Capensis P. L. S. Muller, Vollst. Naturs., Suppl., 1776, p. 165. 

 (Cayenne.") 



Although the Brachysjnsa from the coast of Uruguay near 

 Montevideo belongs to the subspecies argentina, an adult male and 

 three specimens in juvenal plumage secured near Rio Negro in the 

 Departm nt of Rio Negro, a little more than 240 kilometers north, 

 seem best placed under B. c. capensis. The adult male, taken Feb- 

 ruary 17, 1921, in rather worn breeding plumage just beginning 

 the post-nuptial molt, when compared with B. c. argentina., is much 

 darker, with a narrower median crown stripe, broader, bolder black 

 markings on the wings and back, and deeper, more rufescent edgings
