Forster's description is as follows, in translation: "Black with white

spots or bars; abdomen, throat, and eyebrow white; hind neck ferruginous;

breast grey; bill blood-red; iris red. Bill straight, compressed, narrowed

at the top, thicker at the base, and blood-red. The mandibles subequal,

pointed; the upper slightly curved, with the tip pale fuscous; gape medium.

Nostrils almost at the base of bill, linear. Eyes placed above the gape of

the mouth. Iris blood-red. Feet four-toed, split, built for running, flesh

coloured. Femora semi-bare, slender, of medium length.

"Tibiae slightly compressed, shorter than the femora. Four toes, slender,

of which three point forward (are front toes). The middle one almost as

long as the Tibia, the side ones of equal length shorter, the back one

short, raised from the ground. Nails short, small, slightly incurved,

pointed, and light coloured. Head oval, slightly depressed, fuscous. A

superciliary line from bill to occiput whitish. Throat white. Hindneck

ferruginous. Neck very short. Back and rump black, sparsely dotted with

minute white dots. Breast bluish grey. Abdomen, crissum, and loins white.

Wings short, wholly black, variegated with broken white bands. Remiges

short. Rectrices extremely short, black spotted with white, hardly to be

distinguished from the coverts.

Total length from bill to tail 9 inches.

Total length to middle toe 12¾ "

Bill 1-1/10 "

Tibiae 2 "

Middle toe 1-3/10 " "

Mr. Keulemans' plate was done from Forster's unpublished drawing in the

British Museum, and no specimen is in existence. The legs should, however,

be less bright red, more flesh-colour.

Habitat: Tahiti, but evidently long extinct.

This bird, according to Forster, was called "Oomnaa" or "Eboonaa," on

Otaheite, and the neighbouring islands.
