(ed. 9) III, p. 732, ff. 44, 46 (1875). This extraordinary parrot was first described and made known to science by Professor Owen in 1866. He described it from 2 lower mandibles, much damaged, which were dug up from the Mare aux Songes. Except a few further osseous remains, mostly collected by Sir Edward Newton, nothing more of importance was found relating to this bird till Professor Schlegel discovered in the Library of Utrecht the manuscript journal kept during the voyage to Mauritius in A.D. 1601-1602 of Wolphart Harmanszoon, in which among other items of natural history there is a sketch of _Lophopsittacus_ from life, and the statement that it was wholly of a grey-blue colour. From the fact that this bird is not mentioned by the voyagers who visited Mauritius in the 2nd and 3rd decades of the 18th century, it is probable that it was one of the first of the Mascarene birds to become extinct. This is easily understood when we consider that the bird was apparently unable to fly, and would like all big parrots prove excellent eating. Only known from osseous remains and the above-quoted drawing and notes. 35 tarsi and tibiae, and 60 complete and incomplete lower mandibles and fragments of palatine bones in the Tring Museum. Habitat: Mauritius. {51} ARA TRICOLOR BECHST. (PLATE 10.) _Le petit Ara_ D'Aubenton, Pl. Enl. 641. _L'Ara tricolor_ Levaill., Perr. I p. 17, pl. 5 (1801). _Psittacus tricolor_ Bechst., Kurze Ueb. p. 64, pl. I (1811). _Sittace? lichtensteini_ Wagl., fide Bp., Naumannia 1856, Consp. Psitt. Bechstein's description, taken from Levaillant, is (translated) as follows: "This _Aras_, which others have held to be only a variety of _Macao_, is according to Vaillant a distinct species. It is one third smaller than the red-fronted species, or 1 ft. 10 in. long, of which the tail takes 11 inches and the bill 18 lines. The latter is of a black colour and has the upper mandible less curved, and the sides of the lower mandible more swollen than is the case in the other _Ara_ species. The cheeks are naked and white, with three lines of red feathers. Head, front and sides of the neck, breast, belly and thighs red; back of the neck pale yellow; back, shoulders and smaller wing coverts brownish red bordered with yellow or green; flanks yellowish, primaries above dark azure blue, below coppery red. Crissum violet blue, undertail coverts pale blue with green and brown-red borders; under-wing coverts red, the larger yellow, and brownish green. Two centre tail feathers all red with blue tips, the outer ones blue on outer webs and tips, red on the rest of the feather."
