Show 1871.] CERTAIN SPECIES OF TYRANNID/E. 753 Two Cayenne skins of this species are in Mr. Lawrence's collection, and agree very well with specimens in my collection from Bogota and from Panama. Fraser's skins from Babahoyo must also be referred here, although they approximate somewhat to the Venezuelan form (M. rufipennis). The typical specimen of Mr. Lawrence's M. marginatus (from Panama) is a young bird in m y opinion, showing for that reason narrow edgings to the wing-coverts and broader rufous margins to the tail-feathers. But I cannot separate it specifically from other specimens of M. cayennensis from the same district. 4. MYIOZETETES SIMILIS. Muscicapa similis, Spix, Av. Bras. ii. p. 18, pl. 25.

In all freshly moulted specimens of the species which I have seen, there are narrow rufescent edgings to the primaries ; and in this stage it is somewhat hard to give good characters to separate it from M. cayennensis. It is, however, always of considerably larger dimensions, and has the inner margins of the primaries paler and more of a yellowish than rufous tint. When the rufescent outer edgings of the primaries wear off, the species comes nearer to M. texensis, but has the back generally of a darker olive. Mr. Lawrence sends me a skin of Myiozetetes from Peru (Prof. Orton), which agrees very well with others in m y collection obtained by Mr. Whitely at Cosnipata in Peru, and by Fraser at Esmeraldas in Ecuador, the latter being a trifle smaller. Mr. Lawrence has given the M S . term grandis* to his skin; but I am inclined to refer all three to M. similis. 5. MYIOZETETES TEXENSIS. Tyrannula cayennensis, Sw. Phil. Mag. 1827, i. p. 367.
