They do not differ from Ecuadorean examples in Sclater's collection, which he has referred to this species, though Cabanis (Mus. Hein. ii. p. 55) has separated the New-Granadan bird as L.poliocephalus, without having reexamined Peruvian examples. 99. CAMPTOSTOMA FLAVIVENTRE, Scl. & Salv. P. Z. S. 1864, p. 358. Bugaba. A single specimen agrees with our Panama types. At Realejo, in Nicaragua, I found the more northern C. imberbe, Scl. Tyranniscus parvus.

I am quite unable to detect any tangible differences between Costa- Rican, Veraguan, and Guatemalan specimens of this form. Whether R. mesorhynchus, Cab. J. f. Orn. 1865, p. 414, is really separable from R. brevirostris of Mexico, I have no materials to determine. There is a curious feature in the formation of the first primary in this group of the genus, which is not shared by the R. sulphurescens section : the shafts of the outer web are slightly recurved and pointed, and form a stiff pectinated edge. The determination of the sexes in our specimens is not very satisfactory ; but as I find that a |
