The Butterfly Finch inhabits the greater part of the continent of Africa, flying over the country in small parties, that rarely become much increased. The nest, which is seen both during the rainy and dry seasons, is placed upon a low bush, and resembles a rough bundle of hay rather than a cradle for the young. The eggs, from four to seven in number, are long and of a brilliant white. We are told that this species will occasionally steal into a Weaver Bird's nest to deposit its eggs, but cannot speak positively as to the truth of the statement. This elegant Finch, better known upon the Continent as "Cordon Bleu," is lively and restless in its habits, and the attachment testified by one little mate for the other renders them extremely attractive when caged. The only care necessary for their successful rearing is to keep them constantly in a warm atmosphere. * * * * * [Illustration: THE PHEASANT FINCH (_Astrilda undulata_).] Next in order to the preceding we place the ASTRILDS (_Astrildæ_), as closely resembling them in many particulars, the body being slender and the tail wedge-shaped; but the beak, although almost as high and broad as it is long, rises with a decided curve towards the brow. The plumage is very silky, delicately coloured, and marked with a series of undulating lines. Europeans are familiar with two species of this group--the GREY ASTRILD (_Astrilda cinerea_), and the PHEASANT FINCH (_Astrilda undulata_). The coat of the former is brownish grey, lighter upon the lower part of the body, or almost imperceptibly shaded with dark wave-like markings; the tail is white, and its exterior feathers white upon their outer web; the bridles which in this bird pass around the eyes are of a blood-red, as is the beak; the feet are grey. The plumage of the Pheasant Finch is of a brownish grey, fading upon the throat into greyish white; the lower part of the breast and sides of the belly are tinged with rose colour, and the outer web of the exterior tail-feathers are light grey, striped with a deeper shade. In other respects this bird resembles the Grey species; both are alike in their size, which does not exceed four inches.
