Iris purple; bill black; legs dark rose-color; nails gray. Length, 275 to 285. A male measures: Wing, 150; tail, 106; exposed culmen, 20; tarsus, 34. A female: Wing, 141; tail, 100; exposed culmen, 20; tarsus, 34. Two nests with eggs were collected on the Baco River in 1905. The first was taken April 28, and was placed 1.5 meters from the ground on a horizontal limb of a small tree. The two eggs were advanced in incubation. They measure 30 by 22 and 29 by 22. The second nest was similarly placed in a shrub. The nest measures 200 by 280 mm. across the top and is very shallow, the outside depth being about 50 mm. On the bottom are a number of rather large leaves and sticks, topped by fine rootlets and spiral plant-tendrils. The materials were poorly put together so that a large part of the bottom fell off when the nest was removed from its site. The two eggs were well incubated. They measure 29 by 22 and 30 by 21. Their color is light cream. "Common in the old forests in the interior of Mindoro, but very difficult to shoot. We found its nest in a tangle of vines about two meters above the ground. The female flew from the nest to the ground and pretended to be lame. The nest, which contained two young birds, was found in the month of May." (Bourns and Worcester MS.) Subfamily CALOENADINÆ.
