have a slightly paler rump, but cannot he confounded with S. uropygialis, which, 

 moreover, is the Rough-winged Swallow of Colombia. In Ecuador both forms occur. 



There has been some mistake in the enumeration of the specimens in the British 

 Museum 'Catalogue of Birds' (vol. x. App. p. 636), where certain of the Eoraima 

 specimens have been included under the heading of S. nropygialis. 



Azara considered the present species to be rare in Paraguay. Mr. Barrows, how- 

 ever, writing on the Birds of the Bower Uruguay, found it ahundant at Concepcion 

 through the summer, arriving from the north early in August. He writes : — 



" It is said to nest in holes in banks, and I once dug out several deserted Swallows' 

 nests supposed to belong to this bird, though none were seen in the neighbourhood. 

 The nests were of straw and feathers at the end of holes about two feet in depth, and in 

 pretty hard earth, which formed a bank eight or ten feet high, beside a small stream. 

 A bird of this species frequently visited an open and deep well, just in front of my door. 

 I repeatedly saw it descend into the well, but could never see it come out, or find it 

 within. Probably it hid itself between the stones of the wall, where it was prospecting 

 for a home which it failed to find." 



The Sclater Collection has a specimen from the neighbourhood of Rio de Janeiro, and 

 Br. Burmeister considers it to be a common and widely spread species throughout the 

 Campos of the interior of Brazil ; and Lund gives the same testimony regarding the 

 Campos of Lagoa Santa. Burmeister found it nesting at Congonhas. The following 

 localities for the species are given by Natterer : — Bio de Janeiro : July, December ; 

 Casa Pintada : January ; Ypanema : December ; Cuyaba, Caicara : January. He says 

 also that it is found near Cuyaba throughout the year. 



Specimens collected by Dr. Wucherer at Bahia, and by Mr. W. A. Forbes at 

 Pernambuco, are in the Salvin-Godmau Collection ; and Mr. E. L. Layard, writing from 

 Para, observes : — 



"This Swallow is not uncommon, but except in a few favoured localities in the 

 town, I never saw it in any number together. It feeds on minute flies, and perches 

 readily on trees. It is certainly resident in Para all the year round, though it is very 

 scarce from September to December, on the 27th of which month I procured a pair, 

 after noting their absence in September." 



It probably extends throughout the Amazon Valley, as it has been found by Mr. 

 Henry Whitely at Yquitos in March and April, and Mr. Edward Bartlett met with it 

 at Yurimaguas and also on the Upper and Lower Ucayali Rivers. Mr. Henry Whitely 

 also procured specimens at Cosnipata, in Peru, and Mr. Jelski at Monterico. Mr. C. 

 Buckley likewise sent examples from Yuyo in Bolivia. 



The latter traveller also procured this species on the Copataza Biver in Ecuador, 

 and the Salvin-Godman Collection has other specimens from this country. At Esme- 

 raldas and Babahoyo Eraser met with S. uropygialis. A large series was forwarded by 

 Mr. Whitely from lloraima, and a Cayenne specimen, obtained by Jelski, is in the 

 Salvin-Godman Collection.
