apparently not rare in British Guiana. Sir B. Schomburgk found it to be the commonest 

 species on the Barima and Barama rivers, but be did not notice it breeding. Mr. Henry 

 Wliitely procured adult individuals at the end of January on the Atapurau Biver, and 

 in July in the Merume Mountains, but no young birds were in bis collections. We 

 should suppose, however, that the species is a resident in Guiana and breeds there. 



Mr. A. R. Wallace found it common on the banks of the lower and middleBio Negro ; 

 and the late Johann Natterer procured it on the Rio Guapore in July, and on the Bio 

 Negro in December. On the right bank of the latter river he found it common along 

 with Progne tapera. 



The late Mr. C. Buckley obtained specimens on the Copataza Biver, and a nestling 

 at Sarayacu, showing that the species breeds in Ecuador ; and tbat it does so on the 

 Upper Ucayali is related by Mr. E. Bartlett, who also procured specimens at Yurima- 

 guas and on the lakes of Santa Cruz. He writes : — " Breeds in banks along with 

 Stelgidopteryx ruficollis, and lays four or five white eggs. The nest is rather more com- 

 plete in structure than that of the latter, the grass-fibres and bents being finer. Nest 

 taken in July." Mr. Stolzmann also procured this Swallow at Yurimaguas in February. 

 A specimen obtained by Mr. J. Hauxwell at Bebas on the Upper Amazons is in the British 

 Museum ; and in August Mr. Henry Whitely shot a specimen at Chanchamayo in Rem- 

 This record does not appear to have been published by Messrs. Sclater and Salvin, and 

 is omitted in Dr. Taczanowski's work on the birds of that country. Specimens were 

 obtained by Buckley at Yuyo in Bolivia, and a young bird from Cangalli, also pro- 

 cured by Buckley, is in the Salvin-Godman collection. 



The above notes prove the species to be in Biitish Guiana in January and July, and 

 on the Bio Negro in July and December, nesting on the Upper Amazons in July, and 

 occurring at Yurimaguas in February, and at Chanchamayo in August. The moulting of 

 the Guiana specimens in July, as noticed above, proves that they could not be nesting 

 at that time, as they were found to be doing on the Ucayali by Mr. Bartlett during 

 that month, and therefore the habits of the species in different districts of South 

 America appear to vary. It is much to be regretted that so little information is really 

 available for the study of this and other species of South-American Swallows. 



The Blate is drawn from a specimen in the Tweeddale collection, now in the British 

 Museum.
