Having now had an opportunity of comparing Amazonian skins of this Swallow with a specimen from Cayenne, we must pronounce them identical. Such being the case, the present bird must be called H. albiventris, that name having been founded on Buffon's Hirondelle a ventre blanc de Cayenne. 7.

"The nest, like that of Atticora fasciata, is composed of leaves, stems of a prickly climber, fine bents, and fibres of bark very loosely put together, and is placed in holes in banks. Four or five white eggs are laid in September ; but I also took nests on the Huallaga in July."-E. B. Fam. CCEREBIDCE. This characteristic family of the tropics of the New World, although not very rich in species, is, I believe, very abundant in individuals in South America. Of the nine species obtained by Mr. Bartlett, most are widely distributed. The lovely Dacnis flaviventris, Ccereba nitida, and Hemidacnis are, I believe, strictly Upper- Amazonian forms. I have met with skins of all of them in Bogota collections; but these are probably obtained from the wood-region of the Amazonian slope of Columbia. 1. HEMIDACNIS ALBIVENTRIS, Sclater; Scl. & Salv.
