W. E. Brooks — Caslimir Birds. 



[No. I, 



inhabitant of brushwood ravines, at 9 and 10,000 feet elevation ; while 

 P. Tytleri is exclusively a pine forest Phylloscopus. In the places frequented 

 by viridanus it must build on the ground, or very near it ; but our new 

 species builds 40 feet up a pine tree a compact half-domed nest on the side 

 of a fir branch. Eggs pure white. Captain Cock took the only nest obtained, 

 shooting the old bird off the nest. Properly speaking, none of the notes of 

 P. Ty fieri could be called a song, but the song of P. viridanus is not at all 

 a bad one, and quite Phylloscopine. I give measurements of the new bird, 

 and also of P. viridanus for the sake of comparison. Here let me observe 

 that Colonel Tytler is, properly speaking, the discoverer of this interesting 

 Bliylloscopus ; for four years ago he shot one at Simla which, together with 

 one of my own specimens, I have sent to Dr. Tristram for examination. Col. 

 Tytler had labelled the bird Sibilatrix affinis ; while Phylloscopus affinis 

 stood hi his Museum as Asilus ajfinis. As most ornithologists do not recog- 

 nize the generic distinctions of Sibilatrix and Asilus, and as Asilus has been 

 applied to a genus of insects, I have, with Col. Tytler's permission, altered 

 the name of his bird to Phylloscopus Tytleri. The only question remaining 

 is, whether it is distinct from the Pliylloscopi described by the Russian 

 naturalists. Dr. Tristram identifies P. viridanus with P. ScJuoarzi, Radde ; 

 but it is possible that he may have compared the Russian specimens with 

 some of P. Tytleri. The measurements of my specimens are — 



P. Tytleri.

Neither Captain Cock nor I found a nest of P. viridanus. I searched 

 hard, for I was anxious to ascertain to what extent the nest and eggs differed 

 from thoso of P. Tytleri.
