British Guiana. Mus. Brit. P. marail, though resembling the previous species, is readily distinguishable by its smaller size and darker colour, and by the absence of white markings on the upper portion of the back. Its range seems strictly confined to the Guianas. It must always remain doubtful what species Merrem's Penelope jacupema was intended for; but his description seems more applicable to the present bird than to P. cristata, to which it is sometimes referred. 3. PENELOPE GREEYI. Penelope greeyi, G. R. Gray, P. Z. S. 1866, p. 266, t. xxii. Penelope cristata, Pelzeln, Orn. Bras. p. 280 (?). Similis prcecedenti, sed crassitie minore, et colore supra viridi magis purpurascente, forsan diversa: long, tota 24, alee 11, caudee 10*5, tarsi 2*4. Hab. Santa Martha, New Granada. Mus. Brit. This seems to be a small form of the preceding species. Besides the type specimen described by Mr. Gray, we have only seen two other examples, which are now living in the Society's Gardens. If Herr v. Pelzeln's P. cristata be not referable to the present species it must belong to one which we have not yet come across. 4. PENELOPE JACUCACA. Penelope jacucaca, Spix, Av. Bras. ii. t. 69, p. 53; Wagler, Isis, 1830, p. 1110. Salpiza jacucaca, Wagl. Isis, 1832, p. 1226 ; Cab. in Schomb. Guian. iii. p. 745. Penelope superciliaris, J. E. Gray, Knowsl. Menag. ii. pl! 8. Fuliginoso-nigricans, ceneo nitens: tectricibus, plumis sincipitis, juguli, pectoris et epigastrii albo marginatis ; vitta superciliari nivea, inferius atro marginata : aurium plumis nigris albo vario-losis : long, tota 30, alee 13. (Wagler.) Hab. Brazil, prov. Bahia (Spix) ; British Guiana (Schomb.). Mus. Derb. Of this Guan we have only yet met with three specimens, now living in the Society's Gardens. They were purchased of a dealer in Liverpool on the 9th of February last, and were in very bad plumage when received, though now gradually recovering. W e have little hesitation in referring them to Spix's species, when explained by Wagler's diagnosis, which we have adopted in the absence of specimens for complete examination. The "Eyebrowed Guan" of the Knowsley Menagerie is referable to this species, though coloured too rufescent in tint. W e have examined the typical specimen now in the Derby Museum at Liverpool. |
