Mr. W. E. Brooks on a new Upecies of Phylloscopus. 23 



Col, Tytler shot this specimen at Simla; and it corresponds 

 in every respect with my Cashmere specimens. 



Another specimen, and the sixth with which I am acquainted, 

 was shot (by another friend of mine, Capt. Cock) off the nest 

 with four eggs, at Sonamurg, in Cashmere. This was in June 

 last; and Capt. Cock sent me the bird for identification. 



This new Phylloscopus I propose to call 



Phylloscopus tytlert, sp. nov. 



The following are the dimensions : — Length 4*75 in. ; wing 

 2-3; tail Iv; bill at front '36, bill from nostril *3; tarsus '75. 



The dimensions of Phylloscopus viridanus are : — Length 

 5 in. ; wing 2"5 ; tail 2 ; bill at front '3, bill from nostril '29 ; 

 tarsus '8. 



It will be seen from the above that P. viridanus is a larger 

 bird. 



In form, P. tytleri ditFers from P. viridanus by having a longer, 

 narroiver, much more pointed, and very much darker -coloured bill, 

 the lower mandible being black-brown instead of pale fiesh- 

 colour. This alone is quite sufficient to distinguish it : the 

 wing is shorter, but of the same form as that of P. viridanus in 

 regard to proportions of primaries. The tail is shorter. In 

 colour it is of a darker and richer olive on the whole upper 

 parts, and does not appear to have the tail rayed : that of 

 P. viridanus is generally very conspicuously rayed. There is a 

 total absence of the '' slight whitish wing-bar," which I have 

 always observed to be present in P. viridanus, unless the bird be 

 in very abraded plumage. 



In notes and song (if the few notes it utters can be called a 

 song) P. tytleri is utterly different from P. viridanus. Its call- 

 note is very peculiar, and once heard could not easily be for- 

 gotten. In the localities it frequents and inhabits it is quite 

 opposed to P. viridanus. The latter, during the breeding-season, 

 frequents mountain-ravines not far from the snows, which are 

 covered with brushwood and small birch trees ; whilst P. tytleri 

 is a forest Phylloscopus, frequenting the pine-woods belovy the 

 snowy ranges. The only nest found of our new bird was the 

 one above referred to, taken by Capt. Cock.
