The FINFOOTS (_Podoæ_), a group of birds inhabiting South America and Senegal, present many difficulties in their classification, although, judging from their structure generally, and more especially from the formation of their skeleton, they show the closest relationship with the Coots. Their toes are not exactly webbed, but furnished with broad lateral membranes admirably adapted for swimming; their bodies are small and slender, but strongly built; their long neck curves gracefully; their wings are weak and their tail strong and broad. The beak, which is about the same length as the head, is thin and feeble, slightly arched along the line of the culmen, but without any callous prolongation on the brow. The legs are very stout and feathered to the tarsus; the front toes exceed the tarsus in length, and are furnished, as we have said, with lateral folds which perform the office of a web; the hind toe is small and without any appendage; in the wing the second and third quills are longer than the rest; the tail is composed of eighteen feathers, which are slightly rounded at their extremities. THE SURINAM FINFOOT, OR PICAPARE. The SURINAM FINFOOT, or PICAPARE (_Heliornis Surinamensis_), has the head and upper neck black; the back, wings, and tail are brown; a stripe over the eye, the throat and front of neck are white; the breast and belly yellowish white. The eye is brown, beak pale greyish yellow with brown base and black point; in old birds the bill has a red shade. The feet are yellowish red, the inner and hinder parts of the tarsus black, and the toes marked with a black band over every joint. The length of this bird is twelve inches, breadth sixteen inches, length of wing five and a half inches, and tail three and one-sixth inches. According to observations made by the Prince von Wied, the Picapare is to be met with in Brazil and Paraguay, its habitat extending to 25° south latitude, so that it may be said to occur throughout a considerable part of South America. It is by no means scarce upon the rivers of East Brazil, but is often overlooked, as it hides itself amongst the luxuriant vegetation that covers the shore; wherever darkness and silence favour its presence, it is always to be found. Very frequently it may be seen sitting on a thin branch, partially immersed in the water, and occupied in bowing its head in a most peculiar manner. Its food consists of aquatic insects and seeds, in search of which it occasionally plunges its head under water. Its voice, which is emitted from the throat, somewhat resembles the barking of a little dog. We learn from the same authority that the young of these birds are only two in number, and are reared during the hot season. At first they are nearly naked, and hide themselves under the wings of their parents, holding themselves on by means of their beaks; when they have grown a little stronger, they may be seen sitting upon their mother's back, and even accompanying her in her dives under water.
