Land-birds of Juan Fernandez. 179 



The next naturalist that explored Juan Fernandez was the 

 late Mr. Thomas Bridges, C.M.Z.S., so well-known for his zoo- 

 logical discoveries in Bolivia and Chili, of which, most unfortu- 

 nately, no connected account has ever been published. Mr. 

 Bridges paid a visit to Mas-a-tierra, some time in 1853 or 1854,^ 

 and collected a large number of specimens of Humming-birds, 

 but no other birds, so far as I know. Most of the principal 

 collections in Europe were supplied with skins of the Humming- 

 birds of Juan Fernandez by this indefatigable collector*. 



More recently the authoi'ities of the National Museum of 

 Santiago, in Chili, have sent zoological collectors both to Mas-a- 

 tierra and Mas-afuera, and have obtained, beside the Hum- 

 ming-birds previously known, specimens of a closely allied 

 species of Eustephanus from the latter island, and examples of 

 several other species of land-birds hereafter mentioned f. 



From these sources we have become acquainted with the 

 existence of the following species of land-birds in Juan Fer- 

 nandez. 



1. AnjEretes fernandezianus. (Plate VII. fig. 1.) 



Culicivora fernandeziana, Philippi, Wiegm. Arch. 1857, pt. i. 

 p. 265 ; Ph. et Landb. Cat. Aves Chil. p. 22. 



Euscarthmus fernandezensis, Gray, Hand-list, i. p. 351. 



This species is a representative form of A. parulus of Chili, 

 but is distinguishable, as pointed out by Dr. Philippi, by the 

 absence of olive tinge in the plumage, the pure white of the 

 breast and belly varied with more strongly marked black 

 streaks, and the longer bill. The specimens described by Dr. 

 Philippi were obtained for the Museum of Santiago, in one of 

 the collecting-expeditions above mentioned. 



There is a single mounted specimen of this bird in the British 



Trochilus fernandensis and T. stokesi. As has been subsequently shown, 

 they are really male and female of the same species. 



* Mr. Bridges appears to have been quite aware that Eustephanus fer- 

 nandensis and E. stokesi were the two sexes of the same species ; for M. 

 Jules Verreaux informs me that Mr. Bridges expressly spoke of this being 

 the case in conversation with him, at Paris, after his return from South 

 America.
