Mr. H. Durnford on the Birds of 
V.— Notes on the Birds of the Province of Buenos Ayres. 
J By Henry Durnford. 
[Continued from ^The Ibis/ 1877, p. 203.] 
In continuation of my previous notes on tlie ornithology of 
this district (Ibis, 1877, p. 166 et seqq.), I have a few further 
remarks to make on species already mentioned, and other 
species to introduce to the list. The nomenclature used is 
that employed by Messrs. Sclater and Salvin in their ^ No- 
menclator Avium Neotropicalium'’’^. 
1. Geothlypis velata (Vieill.); Nomencl. p. 10. 
Not uncommon at Baradero in April 1876, and found in 
low willows and thickets bordering the river. I have not 
observed this bird near Buenos Ayres. 
[Mr. Durnford^s skins (which he has labelled Basileuterus 
vermivorus) are females of this species.— Edd.] 
2. Cyclorhis viridis (Vieill.) ; Nomencl. p. 13. 
Common in December in the riverain wood at Punta Lara. 
Iris light reddish brown; beak light yellowish brown, under 
mandible lightest; legs lavender, soles flesh-colour. Sexes 
alike. 
3. Progne chalybea (Gm.). 
This is the correct name of the Progne iermQdi P. purpurea. 
Ibis, 1877, p. 168. I called it in my MS. P. domestica, 
which name Dr. Burmeister gave me. P.purpurea, no doubt, 
occasionally comes here; but I have never seen it, and when I 
sent my notes I certainly did not mean to refer to the same 
bird as I saw at Chuput, which was undoubtedly 
and of which I sent skins. 
A* 4. Petrochelidon pyrrhonota. Ibis, 1877, p. 169. 
This Swallow was observed on its migration on the 4th 
March 1877, at Moreno, and on the 15th April 1877, at Lujan 
bridge. On both occasions they were flying steadily N.N.E., 
^ [We have carefully looked over Mr. Durnford’s specimens, and made 
some slight alterations in his nomenclature, so that it may correspond 
exactly with that of the ‘ Nomenclator.’— Edd.]
