the Rio Tuira in Darien in July 1895. In 1946 I saw small flocks 

 around the farms near the mouth of the Rio Jaque. The following 

 year the limit of their range up river was at the head of tidewater

Extension to the west seems to have been slow. Salvin ( Proc. Zool. 

 Soc. London, 1870, p. 211) reported the ani as taken by Arce between 

 1867 and 1869 at Mina de Chorcha, a short distance east of David in 

 Chiriqui, and noted that this was the "most northern locality yet re- 

 corded" for the species on the mainland. Bangs (Auk, 1901, p. 360) 

 reported 5 specimens collected by Brown at Divala farther west in 

 December 1900. Skins in the California Academy of Sciences were 

 taken by Mrs. M. E. McClellan Davidson at Puerto Armuelles Novem-

 at 1,280 meters near Barriles in January 1931, the latter indicating an 

 early extension into the lower mountain area. Monniche collected 1 at
