This is one of the largest water hens found in Brazil, where it is very rare. I am indebted to Dr. Langsdorff for the only specimen which I brought from that country. It differs considerably from the Black-bellied Gallinule of Latham, yet, perhaps, not sufficiently to record it as a distinct species.
Total length fifteen inches and a half; bill one and a half; the base (in the dead bird) orange, the other half green; frontlet none; the crown and nape are grey brown, the sides cinereous, and the throat whitish; the neck both above and beneath for about two thirds its length is lead-coloured; it then changes to rufous, which spreads over the breast, body, wing covers, and greater quills; the lower part of the neck above, with the back, scapulars, and lesser quills, brownish olive; the belly, thighs, tail, and rump black; the inner wing covers are remotely barred with black; legs (in the live bird) red.
Latham describes the Black-bellied G. as seventeen inches long; the bill two inches; the quills greenish brown, with rufous margins; the fore part of the neck and breast bright rufous; and the flanks with black bands.
