Costa Rica. Quite recently Mr. Whitely, of Woolwich, 

 brought me .six specimens which came out of a collection made 

 in Costa Rica, four of them being ferruginous birds with ru- 

 fous tails, clearly belonging to G. ferruyineura, while one 

 should be referred to Ridgway's G. ynoma. The latter spe- 

 cimen has very evident remains of rufous on the white bars, 

 and is apjiroached by another specimen of more general choco- 

 late-brown shade, the tail deep rufous brown, inclining more 

 or less to blackish, and barred with white, all the bars more 

 or less shaded with rufous. The head has less distinct stripes, 

 and seems to indicate that the bird is a younger male. 



In addition to Mr. Whitely^s series, the Museum possesses 

 another Costa- Rican specimen, which has a rufous-brown tail 

 crossed with eight bands of pale rufous bleached nearly white 

 on the centre tail-feathers. In the collection of Messrs. Salvin 

 and Godman is a bird obtained by Carmiol in 1869, which 

 closely approaches the cinnamon-coloured specimens from 

 Brazil, and has, like them, a nearly uniform tail. Two of Mr. 

 Whitely^s examples^ however, so closely approach this bird, 

 that I think it is only an extremely rufous specimen of the 

 northern bird, as it still carries remains of bars on the tail.
