 it also shows no signs of beginning to assume the adult plumagf, and 

 differs from the immature specimen previously described in having six 

 dark transverse bars on the upper surface of the tail and seven on the 

 under surface, also in having a narrow shaft-mark of dark brown on each 

 feather of the throat.

XXXI. — Additional Notes on the Birds of the Islands of Mas- 

 afuera and Juan Fernandez. By Osbert Salvin, M.A., 

 F.R.S., &c. 



Mr. Hanbury Barclay has lately placed in my hands for 

 determination an interesting series of bird-skins, brought 

 from Chili by his brother, Mr. Charles Barclay, and collected 

 by the well-known naturalist, Herr Leybold, of Valparaiso. 

 Amongst them are a series of skins from the island of Mas- 

 afuera, made by an agent of Herr Leybold's. My present 

 notes refer to this portion of the collection ; but I hope at a 

 future occasion to make a further communication on the birds 

 of the rest of the series, which contains some of considerable 

 interest. 



Our knowledge of the ornis of the islands to which I now 

 refer is summarized in a short paper by Mr. Sclater, pub- 

 lished in this Journal (Ibis, 1871, pp. 178-183), since which 

 time the only further reference that has been made to it is by 

 Mr. E. C. Reed', who also communicated some notes on the 

 subject to 'The Ibis' last year (1874, pp. 81-84). 



The contents of Herr Leybold's collection are as follows : — 



OXYURUS MASAFUERiE. 



Many examples, all agreeing closely with one another, and 

 with the bird figured in ' The Ibis ' (1871, t. vii. f. 2). 



CiNCLODES FUSCUS. 

 EUSTEPHANUS LEYBOLDI. 



Several males and two females. The latter confirm the 

 characters pointed out by Mr. Gould in his description of 

 this species, and show that its distinctness from the nearly
