Show 1873.] MR. H. WHITELY ON PERUVIAN HUMMING-BIRDS. 187 colour this species is exceedingly \ikeaOrthogonys viridis the shape of its bill is more that of a Phaznicothraupis. 25. ARREMON SILENS (Bodd.). A skin obtained at Cosnipata agrees in every respect with this species (with which we unite A. torquatus, the Brazilian form), except in having the black collar imperfect in the middle, as in A. semitorquatus. Before separating it specifically, we should wish to see other specimens. 40. THAMNOPHILUS, sp. This is a female of a species of Thamnophilus unknown to us, and probably new. It is of about the same size as Cymbilanius lineatus, and very like the female of that species in colour; but the bill, although thick, is rather that of a true Thamnophilus. The single specimen sent was " shot in the forest" in July 1871. 45. HAPALOCERCUS ACUTIPENNIS, sp. nov. Supra olivaceus, alis caudaque fuscis, olivaceo limbatis : flavus: remigibus quarto quinto et sexto apicibus acutis: rotundata : rostro superiore nigro, inferiore corylino : nigris: long, tota 4*3, alee 1*9, caudee rectr. med,. 1*8, ext. cHa6. Columbia int (Mus. P. L.S.): Peruvia alta (Whitely). Similis H.flaviventri, sed rostro debiliore et remigibus angustatis necnon capite olivaceo dignoscendus. Sclater has long had a Bogota skin of this singular species in his collection, under the M S . name above given. Mr. Whitely's single specimen, obtained at Cosnipata in June 1871, was "shot in the clearing," and is marked male. W e may mention that Arundinicola citreola, Landb., of Chili, is certainly not distinguishable from Hapalocercus flaviventris (cf. P.Z. S. 1867, p. 326). 7. Notes on Humming-birds collected in High Peru. By H. WHITELY, C.M.Z.S.* [Received December 17, 1872.] 1. MYRTIS YARRELLI (Bourc). September 1870. Huasampilla, alt. 10,000 feet, commencement of the valleys of the eastern wood-region.-For some days I was observing a pair of these birds, which came hovering about the blossoms at the very top of a large tree of considerable elevation. I fired several shots without success; but one day getting a clear shot, I fortunately succeeded in killing one of them, but, on account of the dense underwood, it was with the greatest difficulty, * Specimens of all these species (except of the first, which Mr. Whitely supposes to he Myrtis yarrelli) have been submitted to Mr. Gould for determination. I have added the names at the bead of each notice.-P. L. S. |
