Parabuteo unicinctus unicinctus (Teirmiinck) 



No. G 31. Collection - Paris Mus. Wing 312, tail 210, 

 ciilmen from cere 21,3, no sex, tarsus 81.0, middle 

 toe minus claw U0» St. Hilaire. Date - Aug. 1822, 

 Locality - Cap. de. Rio Grande du Sud Tui pris Boa 

 Vista, Bresil, 



Type of the species. Mounted bird in fair con- 

 dition. It is in the dark phase and looks to me like a 

 bird of the year though I cannot be sure. At any rate 

 it looks exactly like the blackish types of young found 

 in Sonora and California. It is marked on the stand 

 "Cap. de Rio Grande du Sud, Tui pris Boa Vista, Bresil. 

 Mr. Aug te St. Hilaire, Aout, 1822 Adult e, G. 31 [the 

 Cat. No]. Falco unicinctus Temm. pi. 313. Type de la 

 planche et de 1' esp§ce." Examined by me on July 28, 

 1933. 



July 31 - Hov;ever I find recent South American specimens 

 fully adult which are exactly like the type. Young S.A. 

 birds are streaked.
