marked with pencilings of pinkish red and scattered spots of the same colour; these 
markings are much blended and concentrated at the larger end. 
H. aglaie is included in the birds of North America as an inhabitant of the Rio 
Grande Valley, but it has not yet, so far as we know, occurred north of the river. The 
western form, H. albiventris, is found in Southern Arizona *.

This species very closely resembles examples of H. aglaie in which the rosy patch 
on the throat is not developed, a character which is never seen in southern specimens, 
but it is evanescent in examples from Nicaragua. 
Its southern range extends to Peru, and it is apparently common in Western 
Ecuador!. Its range northward of the Isthmus of Panama is a little doubtful, and rests, 
so far as Costa Rica is concerned, on a female specimen obtained by Mr. Nutting at 
La Palma®. We have no examples from Chiriqui, but a female from the Isthmus of 
Panama agrees best with others from Western Ecuador. Salmon described the nest 
and eggs of a bird referred to H. homochrous, but his description differs so widely 
from that of the nest and eges of the allied H. aglaiw sent us by Mr. Owen, about 
which we have not the smallest doubt, that we think Salmon wrongly identified the 
nest he found.

Pachyrhamphus, Gray, List Gen. B. p. 31 (1840) ; Scl. Cat. Birds Brit. Mus. xiv. p. 337. 
Of the fourteen species included in this genus, six occur within our limits, the most 
northern of which, P. major, extends its range to the middle of the Mexican State of 
Tamaulipas. The genus is strictly a neotropical one, and spreads over South America 
as far as the Argentine Republic. 
As compared with Hadrostomus, the species of Pachyrhamphus are smaller and more 
slender birds, usually with more mottled plumage, longer wings, and rounder tails, and 
a wide difference in the coloration of the sexes; but P. cinnamomeus and P. rufus are
