corresponding plumage.

The Marmellos bird and the immature male from §. Isabel are practically 
identical with Peruvian and Napo examples. The others have the apical spots to 
the outer rectrices more greyish, thereby approaching the eastern C. 0. obscurus 
(cf. Nov. Zool. xiii. p. 375), but the pale tips are more extended, especially on the 
penultimate and third pair, than in the latter race. 
C. 0. aequatorialis is new to the Brazilian fauna. Its occurrence on the banks 
of the Rio Madeira is not surprising, for it was for a long time known as an 
inhabitant of North-Eastern Bolivia. The Tring Museum possesses a series obtained 
by Mr. Maxwell Stuart at Guanay and San Augustin, on the Upper Beni, and, in 
the British Museum, there is a couple from Mapiri, Buckley coll.
