P. trochilus, which does not inhabit the Altai, must be referable to P. viridanus, which view is 

 confirmed by Homeyer and Tancre, who received five specimens from the Altai, one of which, 

 shot at Kenderlyk on the 27th April, 1885, is in our Museum. Furthermore, Mag. A. Nikolski 

 brought home a specimen from the Altai which he obtained at the end of August in a willow- 

 thicket on the Ilijskij Wisselok. The view expressed by Homeyer and Tancre (Mitth. d. orn. 

 Ver. in Wien, 1883, p. 84), that some of the specimens of P. trochilus obtained by Dr. Finsch 

 might prove to belong to the present species, does not appear to be well grounded, as all Finsch' s 

 specimens were procured in the valley of the Ob, where P. trochilus undoubtedly occurs, while 

 P. viridanus has not been obtained there. 



" From Turkestan we find records by Severtzoff and Russoff. Severtzoff observed P. viridanus 

 in the valley of the Kora, at Kopal, in the spurs of the Alexander range, near Aulie-ata, and in 

 Karatau. Later on he stated that his P. pseudo-borealis, which has been shown to refer partly 

 to P. viridanus, breeds in the mountains of the northern portions of the Ferghana Valley, N.W. 

 of Namanghan, and was obtained in various parts of the Tian-shan, eastward to the upper portion 

 of the Hi. Russoff collected numbers of this bird at Tschinas, and confirmed the records of its 

 nesting on the Iskander-kul." 



To these notes I may add that this Warbler has been met with so far west in Europe as 

 Heligoland, where it has been obtained by Gatke on three occasions — on the 25th September, 

 1878, on the 30th May, 1879, and on the 8th June, 1880. I may also remark that von Homeyer 

 was not the first to point out that the bird obtained by Meves in the Ural, and recorded as 

 P. middendorffi, was really referable to P. viridanus, as Mr. W. E. Brooks examined von Homeyer's 

 specimen in 1877, and the same year (Ibis, 1877, p. 396) pointed out that it was undoubtedly 

 P. viridanus, whereas von Homeyer did not record the fact until 1883. 



It does not appear to have been clearly ascertained how far east the present species is to be 

 met with in Asia. Mr. Oates included it in his ' Birds of British Burmah ' ; but, as he has sub- 

 sequently shown, this was an error, as neither the Hume nor the Tweeddale collections contain 

 a single specimen from that country. 



Dr. Henderson found it common in Hill Yarkand, at the Arpalik River, in August; and 

 Dr. Scully observed it amongst the tamarisk- and willow-bushes fringing the Sanju stream and 

 along the banks of the Karakash River. 



It has been recorded from Gilgit by Dr. Scully and Col. Biddulph, and winters in India, 

 where, according to Mr. Oates (Faun. Brit. Inch, Birds, i. p. 414), it is found " throughout the 

 whole length of the Himalayas from the Hazara country to Sikhim, and over the whole peninsula 

 of India down to Ceylon, with the exception of Sind and the western portion of Rajputana. To 

 the east this species extends commonly to Calcutta, and has been found in Northern Sylhet." 



This Warbler is said to frequent mixed groves and woods ; and, according to Severtzoff, it 

 is to be met with amongst bushes and the tall steppe grass. Dr. Scully noticed it amongst the 

 tamarisk- and willow-bushes, and remarks that it seemed very restless, continually flitting from 

 spray to spray. Both Blyth and Dr. Scully state that its voice is weak, and the former describes 

 the note as tiss-yip, tiss-yip, frequently uttered. Sabanaeff, however, says that the voice of this 

 bird consists of so loud and strong a trill that it can scarcely be recognized as the song of a
