Specimens of this species have also been sent us from Costa Rica. 
They do not differ from Ecuadorean examples in Sclater’s collection, 
which he has referred to this species, though Cabanis (Mus. Hein. 
li. p. 55) has separated the New-Granadan bird as L. poliocephalus, 
without having reexamined Peruvian examples.

A single specimen agrees with our Panama types. At Realejo, in 
Nicaragua, I found the more northern C. imberée, Scl.

received from the Smithsonian Institution.

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. brevircstris of Mexico, I have no materials to determine. There 
is a curious feature in the formation of the fist primary in this 
group of the genus, which is not shared by the R. su/phurescens 
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
