Specimens from Goyaz, S. Panlo, Bahia, etc., are generally of small size, 

 witii a short slender bill, and of briglit coloration. The wing varies in the males 

 from ] r,! to 115, in the females from 110 to 113 mm. 



Skins from Venezuela (Camana and Orinoco), Surinam, British Guiana, 

 Cayenne, Rio Branco and Bogota collections are larger and paler. — Wing: S 6 , 

 115—124; ? ?, 112—120 mm. 



This northern form is probaljly entitled to the name T. alhireritfr epliippialis

In addition to the above specimens, I have examined two others from Catalfio 

 (in the south-eastern corner of the state of Goyaz) collected in ls4G by Castelnaii 

 and Deville, and belonging to the Paris Museum. The six birds which agree in 

 coloration and si/.e with a series from Mattogrosso (3 Chapada, 1 Cuyaba, 1 

 Miranda) are rather pale, greyish brown on the upper parts. Typical skins from 

 S. Panlo (Victoria, Ypanema, etc.), and two adult females from the Rio Jordfio, 

 prov. Araguary, Minas Geraiis, difier slightly in being soirewhat darker and browner 

 on the back and head, but the variation is scarcely appreciable. Specimens from 

 various localities measure as ibllows :
