_Adult_: "Olive brown, the head brown-black; rump and basal upper tail-coverts brown-red, the longest upper tail-coverts olive brown like the back; underparts olive-yellow; quills, primary-coverts, under wing coverts and tail-feathers grey; bill black, base of upper mandible grey; feet brown." (Salvadori, Cat. B. XX p. 579). Wing 5.3 inches, bill 0.8 inches, tarsus 0.8 inches, tail 5 inches. Habitat: Ulietea, Society Islands (fide Latham). The type from the Leverian Museum is in Vienna, and a specimen from Bullock's collection is in the British Museum. These are the only two specimens known, and as it is now more than a hundred years since anyone has procured a specimen, we may suppose that this is an extinct species. The specimen in Vienna, which I have recently been able to examine, has the head, back, wings, and tail deep umber-brown, the rump dark-crimson, upper tail-coverts olive, underside brownish yellow. CYANORHAMPHUS SUBFLAVESCENS SALVADORI. _Parrot from Lord Howe Island_ Phillips, Bot. Bay, p. 225 (1789). _Cyanorhamphus subflavescens_ Salvadori, Ann. & Mag. (6) VII, p. 68 (1891). Very similar to _C. cooki_ and _C. saisseti_ and intermediate in size. Above more yellowish than _C. saisseti_, below more greenish, tail shorter than in either of the latter. This species is believed to be extinct. Last year I received some specimens of a _Cyanorhamphus_ from an inhabitant of Lord Howe's Island, but from subsequent letters these appear to have been collected on Norfolk or Philip Island, and they certainly are _C. cooki_. Habitat: Lord Howe's Island. A pair in the British Museum appear to be the only known specimens. {71} BUBO(?) LEGUATI NOM. NOV. _Strix sp._ Milne-Edwards, Ann. Sci. Nat. (5) XIX p. 13 (art. 3.) 1874. Milne-Edwards had only a single tibio-tarsus of this form and described this bone, but refrained from giving it a specific name, though he stated it was probably a small _Bubo_, in the hopes of getting more material. As, however, we have no further specimens, I think I am justified in naming it after Leguat, who first mentions Owls on Rodriguez. Milne-Edwards' description of this tibio-tarsus is that it equals in length that bone in _Asio accipitrinus_, but was distinguished from the latter by the strong inward curvature and the great development in width of its distal extremity. _Tibio-tarsus._ Total length 77 mm. Length from the proximal extremity to the top of the peronial ridge 25 " Width at distal extremity 10.5 " Width at proximal extremity 9 " Width of shaft 3.7 " Habitat: Rodriguez. {73} SCOPS COMMERSONI OUST. _Scops commersoni_ Oustalet, Ann.
