recurved into a hook very appreciable to the touch. No feathers on the tarsus and toes. Above rather light sooty brown, 
beneath whitish gray, or light brownish ash, becoming nearly pure white in the middle of the belly and on the under tail coverts.

Hah. — United States, from Atlantic to Pacific. 
The rougli-wiuged swallow is common about the sandy cliffs of the bays and inlets of this 
coast. It arrives near the Columbia river in May, and remains until the middle of August, 
when, though in so mild a climate, all the swallows go southward, their last broods being still 
scarcely able to fly. This species burrows holes in soft, sandy banks near the tops of cliffs, 
and has the same habits as the bank swallow of the east. Their only notes are a few chirping- 
calls.— C. 
Rather abundant in both Oregon and Washington Territories. Several specimens were 
obtained by me and forwarded to the Smithsonian museum.- — S.

Sp. Ch. — Largest of N. American swallows. Closed wings rather longer than the deeply forked tail. Tarsi and toes naked. 
Color, in the old male, everywhere glossy steel blue, with purple and violet reflections. Female and immature male less brilliant 
above, pale brownish beneath, blotched with darker or with bluish. Length, 7. 30 ; wing, 5. 85 ; tail, 3. 40. 
Hab. — North America generally. 
On the 23d of May, 1856, I obtained at Fort Steilacoom, Washington Territory, a specimen 
of Progne, agreeing very Avell with a description of P. imr^nirea, with which I at the time 
compared it. Unfortunately the skin was lost, with a large and valuable consignment of 
northwestern birds, which was despatched from Fort Steilacoom to the Smithsonian, but never 
reached its destination. I was especially sorry to lose this bird, as I wished it to be compared 
with such specimens of P. cJiahjbea (vide Cassin' s description of this species) as were in the 
museums of the Philadelphia Academy and Smithsonian Institution. 
My specimen measured 8.50 by 16.38. It is not a common bird in Washington Territory, 
and I Avas only able to obtain this one specimen, although I saw several others at odd times. 
They were then met Avith in groves of scrub -oaks on the Nisqually plains. — S. 
I never saAv this bird in the Territory, Avhere it must be rare. — C.
