The wings are a little longer than the tail, the fourth and fifth primaries being the longest, the third and sixth are shorter, and the second still shorter, being equal to the eighth, and the first is shortest of all. The tail reaches to the end of the digits; it is rounded and not much lengthened: all the retrices are equal in length. The ear-tufts are brown, with some slight buff shading, the discal plumes being white marked with buff. All the upper side is of a dark brown colour, the feathers of the head, the neck and the back are edged with rufous, but not very distinctly so; this rufous colour is more apparent on the scapulars, and some of these even have on the outer web one or two whitish patches surrounded with brown.

The large tail feathers are less brown and more rufous in colour, with lighter rufous marbling mixed with brown.

The tertials and secondaries have a darker brown bar towards the centre, and their outer web is pleasantly marked with somewhat square ocelli or irregular bands of white, pale buff, and brown. The large primaries or

flight feathers present the same ornamentation, but more strongly developed, and the blotches are buffy white on the inner web, which produces a regular spotting on a brown ground colour; the tip of these large feathers is finely stippled with brown on a fairly pale ground; and there is a large patch of white on the wings in addition.

The throat and abdomen are nicely adorned with dark buff feathers, which have a black brown centre and two to four large round white spots. The large feathers on the flanks are whitish, with a brown shaft line and marked with buff. All the well feathered parts, underneath the feathers are covered by a very thick black down."

The colour of bill and feet is reddish brown. Total length, 13½ inches = 345 mm. Desjardins says the specimen he described was killed at the end of October, 1836, in the forest crowning the hills close to "Bamboo Creek." In 1837 several were still seen near "La Savane," and one was killed at Curepipe by Dr. Dobson of the 99th Regiment. This latter is believed to have been one of, if not the last of this species, so we have to thank that excellent naturalist, Desjardins, and Monsieur Jossigny, the companion of Commerson, that we know what this extinct species was like.

Habitat: Mauritius.
