Measurements (in millimeters). — Males (3 specimens), wing 150.5- 

 157.5 (152.8), tail 113.5-120 (115.8), exposed culmen 33-37 (35.4), tarsus 

 29.0-29.5 (29.3). 



Females (6 specimens). Wing 147-163.5 (157.7), tail 114.3-125.5 

 (119.3), exposed culmen 36^0 (37.7), tarsus 28.2-30 (29.1). 



Type, adult female, wing 152.5, tail 125.5, exposed culmen 37, tarsus 29. 



Range. — Specimens seen from Bariloche, Rio Negro; Rio Chico and 

 Maiten, Chubut, Argentina. 



Reynarks. — This form of the Chilian flicker apparently ranges through 

 the wooded eastern slopes of the Andes in Argentina from the vicinity of 

 Lake Nahuel Huapi southward at least through the territory of Chubut. 

 Specimens taken west of the Andes are not available from south of Con- 

 cepci6n, Chile, so that the subspecific identity of the flickers of south Chile 

 is uncertain. The difference in length of bill between these two forms of 

 pituis is easily seen from the following measurements (in millimeters) of 

 the bill in typical C. p. pitius (specimens from Concon, Santiago and 

 Concepci6n): males (5 specimens) 40.5-44.4 (41.9); females (2 specimens) 

 39.5-41.5 (40.5). 



The characters used^ in segregating Pituipicus Bonaparte,^ type Picus 

 chilensis Lesson (equivalent to P. pitius Molina), seem insufficient to war- 

 rant the maintenance of a monotypic genus for the present species, especi- 

 ally with the recognition of the short-billed southern and eastern race 

 cachinnans. We have therefore included pitius (together with the flickers 

 often separated under the generic division Soroplex) in the genus Colaptes. 



Brachyspiza capensis choraules, subsp. nov. 



Characters. — Similar to Brachyspiza capensis chilensis (Meyen) but paler; 

 superciliary stripe whiter especially posterior to the eye; sides and flanks 

 lighter, more buffy; rufescent edgings of wing feathers paler. 



Description. — Type, U. S. National Museum, Cat. No. 284125, adult 

 male in somewhat worn plumage, from General Roca, Gobernaci6n de Rio 

 Negro, Argentina, collected November 30, 1920, by Alex. Wetmore (orig. 

 No. 5484). Crown dull neutral gray, with a rather narrow black line on 

 either side extending from base of no.stril to nape ; lores, a faint line on fore- 

 head at base of culmen, and superciliary stripe whitish, with a slight 

 admixture of pallid neutral gray; feathers on lower eyelid dull white, those 

 immediately anterior to eye a mixture of dull white and dull black; line 

 from eye to nape, somewhat broadened posteriorly, black ; auricular region 

 light mouse gray, with a white spot behind it; a poorly defined subauricular 

 streak, blackish; hindneck tawny, this color extended in a half collar 

 around on sides of neck; lower hindneck and upper back drab; rest of back 

 slightly duller than drab, each feather streaked with fuscous-black; rump 

 and upper tail-coverts slightly paler than hair brown; primaries and secon- 

 daries darker than fuscous, the outer primaries margined with whitish, the 

 inner ones and the secondaries with pinkish buff, changing to bister toward
