The eggs are usually five in number, nearly round, highly polished, and of a dark-reddish-purple or wine colour; but this beautiful tint in a short time changes to a dull leaden hue. The nest is a mere scrape, insufficiently lined with a few grass-leaves. The young birds appear to leave the mother (or father, for it is probable that the male hatches the eggs) at a very early period. When still very small they are found living, like the adults, a solitary life, with their facilities, including those of flight and the melodious voice, in a high state of perfection. 428. NOTHOPROCTA PENTLANDI (Gray). (PENTLAND'S TINAMOU.) +Rhynchotus pentlandii+, _G. R. Gray, List of Gall. B. M._ p. 103 (1867). +Rhynchotus punctulatus+, _G. R. Gray, ibid._ (jr.). +Nothoprocta doeringi+, _Cab. J. f. O._ 1878, p. 198 (Cordova); _White, P. Z. S._ 1883, p. 432 (Cordova). _Description._--Above cinereous; head and back banded with black bars, which are bordered with ochraceous; back also varied with longitudinal whitish streaks; wings cinereous, with pale ochraceous cross bars on the outer webs: beneath pale cinereous; throat whitish; breast and sides of belly with rounded whitish spots; middle of belly creamy white; bill and feet reddish: whole length 8·0 inches, wing 5·5, tail 2·0. _Hab._ Andes of Bolivia and Northern Argentina. We have been able to compare a typical specimen of _Nothoprocta doeringi_, received from Dr. Doering of Cordova, with the series of specimens of this group in the British Museum, and find that Dr. Cabanis's name must give way to G. R. Gray's prior designation. Dr. Doering's specimens of this species were obtained in the Sierra de Cordova. The original example of _Nothoprocta pentlandi_ was procured by Pentland, the well-known scientific traveller (after whom it is called), in the Andes of Bolivia. 429. NOTHOPROCTA CINERASCENS (Burm.).
