Show 1870.] MESSRS. SCLATER AND SALVIN ON THE CRACIDiE. 537 pallide grisescenti-viricli, hypochondriis et crisso rufescentibus: cauda ceneo-viridi, rectricibus externis pro majore parte castaneis: rostro plumbeo apice albicante, pedibus corylinis: long, tota alee 8*5, caudee 9*5, tarsi 2*5. Hab. Upper Amazon (Spix) ; Bogota (Mus. S.-G.) ; Rio Napo (Verreaux); wood-region of Eastern Peru (Tschudi); Cosnipata valley (Whitely) ; Bolivia (Bridges in Mus. Brit.); Mato Grosso and Rio Madeira (Natterer). Mus. Brit., Vindob., Smithson., et S.-G. W e have a typical example of Tschudi's Ortalida adspersa, received in exchange from Neuchatel, and have seen a second (from the same source) in the Smithsonian collection. W e regard them as clearly referable to Spix's O. guttata. W e have also before us one of the Nattererian skins called O. albiventris by v. Pelzeln, which is certainly the same bird. The range of this Guan is therefore widely extended throughout Upper Amazonia from Mato Grosso to the slopes of the Andes of New Granada, where it comes within the grasp of the Bogota bird-hunters. 11. ORTALIDA SUPERCILIARIS. Ortalida superciliaris, G. R. Gray, List of Gall. p. 10. fEneo-viridis, fronte et superciliis albescentibus; subtus magis olivacea, cervicis et pectoris plumis albo marginatis: grisescente, hypochondriis et crisso rufescentibus: long, 16*9, alee 7, tarsi 1*9. Hab. South America. Mus. Brit., Derbiano. The typical specimen of this bird, now in the British Museum, died in this Society's Gardens, and its locality is unknown. There is a specimen in the Derby Museum which we consider referable to the same species. It was purchased from Mr. Gould in 1846. This is a small species, of about the same size as O. araucuan, but distinguishable from that bird by its white eyebrows and spotted breast. W e have some little suspicion that it may be a dwarfed variety of O. guttata. 12. ORTALIDA POLIOCEPHALA. Penelope poliocephala, Wagl. Isis, 1830, p. 1112. Ortalida poliocephala, Wagl. Isis, 1832, p. 1227; Scl. & Salv. P. Z. S. 1869, p. 364.
