 * Scops commersoni Oustalet, Ann. Sci. Nat. (8) III, p. 35 fig. 3 (1896).

HIS owl, I believe, is not a true Scops, being much too big, but we must leave it in that genus for the present, as there are no specimens or bones extant, and only Jossigny's drawing to guide us as to its appearance. The first mention of owls on Mauritius was in the year 1606, when Admiral Matlief says that owls were common in the Island. Monsieur Desjardins, in 1837, gave the first accurate description of the bird, of which I here reproduce the translation. "The digits and even the tarsi are not feathered, only on the front portion of these latter one sees some short, stiff feathers running down to a point nearly to the centre. The digits are very strong, they being armed with hooked nails.

The beak is very stout, arched from its base; the upper mandible, which is much longer than the other and covering it, is as if cut square at the point. The nostrils pierce the bill pretty high up in the horny portion. The eyes, of which I could not see the colour, are round, and placed, like in the entire family, in front. They are surrounded by a circle or disc of stiff, thread-like feathers, which is interrupted at the sides. A sort of collar is perceptible on the throat. Two tufts, similar to those of the Eagle Owls and Eared Owls, and very apparent, are behind the eyes and towards the top of the occiput.

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
