Show 1868.] MESSRS. SCLATER AND SALVIN ON PERUVIAN BIRDS. 175 our inspection, we have convinced ourselves that his M. rufescens is the same as M. nationi, Sclater. The locality given by Dr. Salvadori, however, is erroneous, the bird being probably restricted in its range to the western coast-region of Peru*. 7. PYROCEPHALUS RUBINEUS (Bodd.). A pair of this widely spread species, accompanied by a specimen of the form called P. obscurus by Gould and P. atropurpureus by Cabanis (Tsch. F. P. Aves, p. 156), which we are now inclined to regard as in all probability a melanism of the same bird. 8. CERYLE CABANISI (Tsch.). Originally described from specimens obtained by Tschudi in the vicinity of Lima. This is the most southern locality we have yet met with for this western representative of C. americana, which ranges northwards up to Texas. We have seen specimens from Panama, Costa Rica, Guatemala, and Mexico. 9. CHORDEILES PERUVIANUS. Chordeilespruinosus, Tsch. Consp. Av. p. 8, et F. P. t. 6. fig. 2. Chordeiles semitorquatus, Tsch. F. P. Aves, p. 130. Chordeiles peruvianus, Peale, Zool. U. S. Expl. Exp. Birds, p. 172 (1848). Chordeiles acutipennis, Cassin, ibid. ed. ii. p. 189 (1858). Caprimulgus exilis, Less. Rev. Zool. 1839, p. 44 (?). An adult male of this interesting species, which turns out after all to be quite distinct from the eastern C. acutipennis. It is easily distinguishable by the white bars on the inner webs of the rectrices, which are five or six in number besides the white subterminal bar, which crosses both webs. It is besides much whiter and paler underneath generally. 10. CROTOPHAGA SULCIROSTRIS, Sw. This is, again, a purely western species, extending hence, which is the most southern locality hitherto noted for it, through Central America into Southern Mexico. 11. PHOLEOPTYNX CUNICULARIA (Mol.). 12. URUBITINGA UNICINCTA (Temm.). * Concerning other American species described by Dr. Salvadori (I. c), -we have arrived at the following conclusions from examination of his typical specimens:- Bhynchocyclus cerviniventris, Salvad. Att. S. It. vii. p. 153= Contopus pallidus (Gosse); Anceretes cristatellus, Salvad. I. c. p. 153= Serpophaga subcris-tata (Vieill.); Thamnistes affinis, Salvad. I. c. p. 154= Thamnomanes glaucus $ Myrmotherula minor, Salvad. 1. c. p. Ib7-M. brevicauda (Sw.); Myrmeciza marginata, Salvad. I. c. p. 158 = M. ruficauda (Max.). Porphyriops leucopterus, op. viii. p. 382, is different from Porphyriops melanops, but may be probably identical with Tschudi's Crex femoralis. There is a specimen of this bird in the Derby Museum, Liverpool, from Bogota. It seems to be a good second species of the genus Porphyriops. |
