Mr. P. L. Sclater on the genus Muscisaxicola. 57 



also had the advantage of examining specimens of the new 

 species described therein, which Mr. 0. Salvin has lately ob- 

 tained from Herr Dr. F. Leybold of Santiago, through Dr. J. A. 

 Kiihn of Munich, I beg leave to be allowed to offer a ^evv re- 

 marks upon the subject, taking the species in the order given 

 by Messrs. Philippi and Landbeck. 



1. Muscisaxicola albifrons (Tsch.) ; Philippi & Land. Z. c. 

 p. 78. 



Of this species I possess specimens obtained by Mr. Eraser on 

 the Andes of Ecuador (Panza and Pichincha), as recorded in the 

 Zoological Society's 'Proceedings' for 1860, pp. 78 and 92. I 

 have little doubt of the identity of my birds with Tschudi's 

 Ptyonura albifrons, although I agree with Messrs. Philippi and 

 Landbeck that the figure in the ' Fauna Peruana' is barely reco- 

 gnizable. But I rather doubt whether the bird obtained by 

 Froben above Tacna in Peru, and described by Messrs. Philippi 

 and Landbeck, really belongs to the same species. I certainly 

 could not attribute to my skins a " weisslicher Spiegel auf den 

 FlUgeln." In both my specimens the wings are dark greyish 

 black, with very narrow greyish edgings to the secondaries and 

 coverts, but hardly any edgings perceptible on the primaries. 

 The habitat of M. albifrons appears to be Northern Peru and 

 the highlands of Ecuador. 



2. Muscisaxicola cinerea, Philippi & Landb., nov. sp., /. c. 

 p. 80. 



This may possibly be the same species as that described by 

 Lafresnaye (Rev. Zool. 1855, p. 61) as M. albimentum, although 

 Lafresnaye's expression " supra tola fusco-grisea, pileo brunnes- 

 centi-fusco " does not quite suit M. cinerea, of which the head 

 is nearly uniform grey with the back. M. cijierea lives in the 

 Cordilleras of Santiago, Chili, at a height of 10,000 feet above 

 the sea-level. 



3. Muscisaxicola maculirostris, Lafr. & d'Orb. ; Philippi 

 & Landb. /. c. p. 82, appears to have a very wide range, Mr. Fraser 

 obtained examples at Calacali, in Ecuador, 8000 feet above the 

 sea-level, which are now in my collection. D'Orbigny procured it 

 on the high tableland of Bolivia, near La Paz. Burmeister records
