752 MR. P. L. SCLATER ON [Dec. 5, 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. In 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 m y 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:- M. erythropterus ») it M. cayennensis... ii n M. rufipennis ... Mus. P. L. S Mus. G. N. L. ex Cayenne ... Fl *» 11 Mus. P. L.

Myiozetetes cayennensis, Scl. et Salv. P. Z. S. 1868, p. 628. This form is intermediate between M. cayennensis and M. ery­thropterus. 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. ery­thropterus, the dark line 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. 3. MYIOZETETES CAYENNENSIS. Muscicapa cayennensis, Linn. S. N. i. p. 327 (ex M. cayenn.

I have hitherto applied the Linnean term cayennensis to the southern form of M. texensis, without rufous margins to the wino-s. 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 tbe name Myio­zetetes cayennensis is correctly applicable to the bird which I have hitherto usually called M. guianensis.
