abundant, and nested in the holes of dead trees along the river banks. 
As these trees disappeared, the Swallows removed to some more suitable 
locality. I have never known them to breed in bird-boxes in this 
vicinity, though they sometimes do so in Northern Ohio. In the Hast- 
ern States they have almost forsaken their primitive manner of breeding, 
resorting to bird-boxes for that purpose. In Ohio the White bellied 
Swaliows nest in the deserted hole of a Woodpecker, or natural cavity 
of a dead tree, always in the vicinity of water. Even during their 
migrations the birds are seldom seen far from running streams. The 
nest is built of leaves and grass, and thickly lined with down and 
feathers. The eggs are white, unspotted, and of oblong oval shape, 
measuring about .80 by .5o. 
GENUS PELROCHELIDON. Cabanis. 
Bill stout and deep, somewhat as in Progne. Nostrils entirely superior, open, without 
overhanging membrane on the inner (or upper) side, but somewhat overhung by short 
bristies, seen also along the base of mandible and in chin. Legs stout, the tarsi short, 
not exceeding the middle toe exclusive of its claw; feathered all round for basal third 
or fourth, though no feathers are inserted on the posterior face. Tail falling short of 
' the closed wings, nearly square or slightly emarginate; the lateral feathers broad to 
near the ends, and not attenuate.

This Swallow, like the preceeding, migrates along the banks and over 
the beds of streams. They are very variable in their numbers in differ-
