on the wings. In M. erythropterus nearly the whole of the basal 

 two thirds of the remiges are of a chestnut-red ; and a conspicuous 

 red patch on the wing is thus formed. Except in the first primary, 

 the black colour is confined to a very narrow line on each side of the 

 shaft. Iu the secondaries the outer web is black, narrowly edged 

 with red ; the inner web nearly wholly red. The whole wing-end 

 and outer secondaries are black. 



I have two specimens of the bird in my collection — one obtained 

 from a dealer, the other transmitted by Mr. Rogers from Minas. 



This species (or subspecies of M. cayennensis, whichever it may 

 be) is of larger size than M. cayennensis from Cayenne. I measure 

 as follows : — 



2. Myiozetetes rufipennis.

Myiozetetes cayennensis, Scl. et Salv. P. Z. S. 1868, p. 628. 



This form is intermediate between M. cayennensis and M. ery- 

 thropterus. Mr. Lawrence's typical specimen agrees very nearly 

 with Goering's skin from San Esteban, which Mr. Salvin and I did 

 not venture to separate from M. cayennensis. 



M. rufipennis has not quite so much red on the wings as M. ery- 

 thropterus, the dark Une adjoining the outside of the shaft of the 

 primaries being broader. Judging from the two specimens examined, 

 the bird is also not quite so long-winged as the Brazilian form.

I have hitherto applied the Linnean term cayennensis to the 

 southern form of M. texensis, without rufous margins to the wings. 

 Dr. Finsch, however, in his remarks above mentioned, has shown 

 conclusively that the Muscicapa cayennensis of Linnaeus (founded on 

 M. cayennensis of Brisson) has the remiges externally margined with 

 rufous. There can be no doubt, therefore, that the name Myio- 

 zetetes cayennensis is correctly applicable to the bird which I have 

 hitherto usually called M. guianensis.
