BIRDS — COLYMBIDAE PODILYMBUS. 
837 
A very small species, P. dominions, (Linn.) will, without doubt, be found to inhabit our 
southern border. A specimen in the Philadelphia Academy was obtained by Dr. Gamble on the 
Gulf of California, and I have specimens from eastern Mexico and Cuba. It measures but 
9 inches total length ; the wing, 3-f ; the upper parts are brownish black, the greater part of the 
secondaries and the inner edges of the primaries white ; cheeks and throat blackish ash grey ; 
breast and abdomen white, mottled with ashy brown.

Sp. Ch. — Adult. " Bill black, tinged with blue. Iris blood red. Feet dusky grey externally, greenish grey on the inner side. 
The tufts on the sides of the head are orange, anteriorly more yellow, posteriorly red ; the head and upper part of the neck are 
deep black ; the rest of the upper parts brownish black, the wings greyish brown, with a broad patch of white, the secondary 
quills being of that color. The throat, fore part and sides of the neck are dull black, its lower part with some spots of the 
same; the rest of the lower parts glossy silvery white, excepting the sides of the body and rump, which are light red." 
"Length 13 inches ; wing, 5. x 8 5 ; bill, \\ ; tarsus lj 3 ." 
Mr. Audubon being the first to introduce this species into our fauna, I have copied his 
description, which was taken from specimens lent him by the Earl of Derby, said to have come 
from North America. There are no American specimens in any of the collections in this country, 
but as it is common in the north of Europe, it may occasionally visit Arctic America by the way 
of Greenland, where many European species are recorded as being found, that have not yet been 
observed on our continent.
