BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 121 



General Eoca, Rio Negro, from November 23 to December 3 the 

 birds were found in small sloughs, or, with bands of the larger 

 bodied F. armillata^ on open channels. From their actions they 

 seemed to be breeding, but no nests were found and Doctor Dabbene 

 states that they do not nest until the end of January or the first part 

 of February.^ 



Near Carhue, Buenos Aires, white-winged coots were found from 

 December 15 to 18 in a little fresh-water marsh that bordered an 

 arroyo draining into Lake Epiquen. Truculent males grasped one 

 another by the feet and then struck savage blows with their pointed 

 bills. From March 3 to 8, 1921, bands of adults and young were 

 found along the open shores of the Laguna del Monte at Guamini, 

 where there were no growths of rushes of any kind. One was noted 

 on the Rio Aconcagua near Concon, Chile, on April 28. 



An adult female shot October 31 had the bill, eye, and legs colored 

 as follows: Tip of bill Biscay green, shading inward to dull green- 

 yellow; basal half of bill pale vinaceous fawn, becoming whitish at 

 extreme base; base of mandible tinged with green; frontal shield 

 slightly paler than strontian yellow; iris mars orange; tarsus and 

 toes Paris green, with posterior face of tarsus and outer margin of 

 lobes on toes dawn gray, shading on the outer margins of the lobes 

 to castor gray. 



Skins of the white- winged coot are marked by the greenish crus 

 and the orange or yellow shade of the frontal shield. The median 

 under tail coverts vary from black to dark neutral gray, the outer 

 margin of the tenth primary is margined with white, and the sec- 

 ondaries are tipped more or less extensively with white. The frontal 

 plate is rounded posteriorly and the tail measures from 48-.56.5 mm. 

 There is little or no white on the abdomen. 



Measurements of a pair are as follows: Male, wing, 191.0; tail, 

 56.5 ; tarsus, 58.0 ; female, wing, 173 ; tail, 50.6 ; tarsus, 52.5 mm. 



GALLINULA CHLOROPUS GALEATA (Lichtenstein) 



Crex galeata Lichtenstein, Verz. Ausgest. Saug. Vog., 1818, p. 36. (Brazil.) 



The validity of this form, as distinct from G. c. cachinnans Bangs 

 from North America, is sustained by a series of five males and two 

 females secured August 9 and 16, 1920, at the Riacho Pilaga, For- 

 mosa. Individuals in adult stage are readily separated from similar 

 specimens of cachinnans by their more olivaceous, less brownish 

 backs. In addition the white of the abdomen, when birds are viewed 

 in series, is less extensive in southern than in northern birds, and 

 may be practically absent in adults of galeata. The white on this 

 area, however, varies so with age as to be of little use in studying
