The general resemblance between this and the European Kingsfisher may have been the cause why it has remained hitherto unnoticed by ornithologists. It bears, however, on closer inspection, a strong and peculiar distinction in the crest at the back of the head, in being much smaller in size, and especially as inhabiting the hottest parts of India; while our own braves the cold of a Siberian winter. Total length six inches, of which the bill from the angle of the mouth to the tip occupies one inch and three-quarters, and is black, with the under mandible paler; the ears and the upper part of the head and neck are blueish-black, transversely banded with somewhat crescent-shaped narrow bands of a rich deep blue, which are broken into spots on the crest and ears: from the base of the under mandible is a black stripe richly glossed with blue, and carried down on each side the neck, between which and the upper part is a whitish stripe beginning just behind the ears (this in the European species is rufous). The wing-covers, scapulars and lesser quills are blackish glossed with blue, the two former having a bright spot at the end of each feather; superior and greater quills entirely blackish; down the middle of the back, rump, and tail-covers, light and vivid blue, with a slight tinge of greenish; chin and throat cream-colour; line between the nostrils and eyes, margin of the shoulders, under wing-covers, and all the lower parts of the body, rufous; tail deep and obscure blue; legs red. My specimen came from some part of India; I have met with others from the same place; and Dr. Horsfield has likewise observed it in Java. * * * * * Pl. 51 [Illustration] COLIAS Pyrene. _White African Colias._ * * * * * GENERIC CHARACTER.--See Pl. 5. * * * * * SPECIFIC CHARACTER. _C. alis albis; anticis supra punctulo nigro subcentrali oblongo ad apicem approximante; posticis margine integerrimis; singulis subtus puncto ocellari lineisque fulvis undulatis: sexibus similibus._ Wings white; anterior with a small, nearly central, oblong, black dot nearest the tip; margin of the posterior wings very entire, beneath all with a brown ocellate spot and undulated fulvous lines: both sexes alike. * * * * *
