Mr. P. L. Sclater on the genus Muscisaxicola. 
also had the advantage of examining specimens of the new 
species described therein, which Mr. 0. Salvin has lately ob¬ 
tained from Herr Dr. P. Leybold of Santiago, through Dr. J. A. 
Kuhn of Munich, I beg leave to be allowed to offer a few re¬ 
marks upon the subject, taking the species in the order given 
by Messrs. Philippi and Landbeck. 
1. Muscisaxicola albifrons (Tsch.); Philippi & Land. 1. c. 
p. 78. 
Of this species I possess specimens obtained by Mr. Fraser on 
the Andes of Ecuador (Panzaand 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 f 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 
FlugelnP 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., L 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. cinerea 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
