T h e fact of Central America having a fauna peculiarly its own has been frequently mentioned in the pages
o f the present work; and so decidedly is this the case, that while it comprises certain species and even
genera which do not exist elsewhere, the species there found are generally representatives of others
inhabiting South America proper, or that portion o f the continent to the southward o f Panama. Numerous,
however, as are the little Phaethornes inhabiting the latter country, only one has, so far as is yet known,
been found in the former—namely the P . Adolphi. M. Sallé, while residing at Cordova, during his recent
visit to Mexico, collected numerous specimens o f this bird, and appears to have subjected them to a careful
examination of their internal parts, in order to ascertain the sexes with certainty; and, if reliance can be
placed upon his investigations, it would seem that all those with short and rounded tails are males, while
the females have the two central feathers more prolonged, and the lateral ones with a dark zone between
their bronzy bases and buff tips. Supposing this information to be correct, a highly interesting fact has
Jieen ascertained, and one which will form a key as it were to the sexual markings o f other allied species,
"some o f which present similar characters; and it becomes necessary, now, to ascertain if the larger
members of the genus Phaethornia and those o f Glaucit are subjected to the same law.
Besidés specimens from Cordova, I have received many others from a very different locality, Guatemala,
whence at least ten individuals were transmitted to me by George Ure Skinner, E sq .; these, however, had
not been subjected to dissection. A locality still farther south may, if I mistake not, be assigned to this
bird, Mr. Lawrence o f New York having a specimen, collected in Veragua, which I believe to be identical
with the present species, and which was procured by Dr. Merritt, the discoverer o f the interesting
albocoronata; the whole o f Central America, therefore, from the Isthmus o f Panama to Mexico, may be said
to he inhabited by this bird. The species to which it is most nearly allied is the Phaethorms griseogulam,
from which it differs in its larger size, the still darker and more smoky colouring of the under surface, and
the uniform deep olive-green colouring o f the tail, the lateral feathers o f which are not so largely tipped
with buff.
Head, upper surface and wing-coverts dark bronzy-brown; tail-coverts rufous; tail dark bronzy-green
tipped with buff, fading into white at the extremity; wings purplish-brown; ear-coverts dark brown; under
surface buff, with a wash o f grey on the throat and breast; upper mandible and apical half o f the lower
mandible black; basal half o f the latter bright yellow; legs and feet brownish-yellow.
The Plate represents the birds of the natural size.
