Order CORACIIFORMES.
FROGMOUTHS, ROLLERS, KINGFISHERS, HORNBILLS, BEEBIRDS, GOATSUCKERS, AND SWIFTS.
Claw of hind toe shorter than that of third toe; two toes united for their basal joint; or, if toes are free, then the feet small and weak and gape deeply cleft. Toes usually three in front, one behind; in some, two in front and one behind; rarely, four in front and in pairs. Bill large and with a horny crest, often bright red in color, when not red the surface more or less sculptured (Bucerotes); or, bill long, straight, tapering, and sharp, usually red or black (Halcyones); or, bill slender and gently curved, tail long (Meropes); or, bill stout, gape wide (Coraciæ and Podargi); or, bill minute and weak, gape wide and deeply cleft (Caprimulgi and Micropodii). This order is an extremely unsatisfactory one as its members have few external characters of ordinal value. The suborders Caprimulgi and Micropodii seem to be particularly out of place.
