1868.] MESSRS. SCLATER AND SALVIN ON PERUVIAN BIRDS. 1/5 



our inspection, we have convinced ourselves that his M. rvfescens 

 is the same as M. nationi, Sclater. The locality given by Dr. 

 Salvador!, 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. ohscurus 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. 



Chordeiles j)rmnosus, 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 acutipentiis, 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 un- 

 derneath 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. Salvador! (/. c), we 

 have arrived at the following conclusions from examination of his typical speci- 

 mens : — Rhynchocyclus cerviniventris, Salvad. Att. S. It. vii. p. Ib^^Contopus 

 pcdUdus (Gosse) ; Ancsrefes cristafellus, Salvad. I. c. p. 1.53 = Serpophaga subcris- 

 tata (Vieill.) ; Thamnistes affinis, Salvad. I. c. p. 154= Thamnomanes glaucus ^ ; 

 My r mother ula minor, Salvad. I. c. p. 157 = M. brevicaucla (Sw.) ; Myrmcciza mar- 

 ginata, Salvad. I.e. p. 158=iir. ruficauda (Max.). Porphyriops kucopterua, op. cif. 

 viii. p. 382, is different from Porphyriops melanops, but 7nay be probably iden- 

 tical with Tschudi's Crcx 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.
