only to his two undoubted specimens of P. proregulus. These came from the Stanowoi 

 Mountains — one from the Ssalurnai River, and the other from Markul. With regard to the 

 occurrence of this bird in the southern Ussuri country, Mr. Maximovicz obtained the most 

 northerly recorded specimen at Stanitza Busse. Prjevalski records it as tolerably common in 

 the vicinity of Lake Chanka, though it is not included in his account of his journey, because 

 he mistook the only specimen he brought back for P. superciliosus. Dorries sent specimens 

 to Europe from the station of Baranovskij, in the Ssuifun Valley ; and Mr. Poljakoff from the 

 mouth of the Retschnoje River. Finally, the brothers Dorries and Mr. Jankovski record this 

 species from the Island of Askold." 



Pallas's Willow- Warbler breeds also in the Himalayas at considerable altitudes ; and 

 Capt. Cock took several nests with eggs at Sonamerg in Kashmir ; Col. Biddulph records it 

 from Gilgit in January; and, according to Mr. Oates (Faun. Brit. Ind., Birds, i. p. 408), "it is 

 distributed throughout the Himalayas from Hazara and Kashmir to Bhutan, and also occurs, 

 probably only as a winter visitor, in the Khasi and Naga Hills, in Manipur, and in the Salween 

 district of Tenasserim, among the pine-forests. It occasionally descends to such low levels as 

 the Dehra Doon." 



According to Abbe David (Ois. Chine, p. 275) it frequently passes the winter in Central and 

 Southern China; and Mr. Styan (Ibis, 1891, p. 339), in his article on the birds of the Lower 

 Yangtse Basin, says that it " begins to arrive early in March, and soon after its sweet and 

 powerful song is heard throughout the day from the tops of the bamboos and firs ; its call-note 

 is a loud Canary-like hweet. Most of them pass on by the middle of April; in October they 

 reappear, and I have obtained one at Kiukiang as late as December." 



According to Mr. Gatke (Ibis, 1889, p. 578) there are differences between the northern form 

 which breeds in Siberia, and the southern form, which breeds in the Himalayas, sufficient, in his 

 opinion, to justify their being separated, at least subspecifically, and he proposed to give the latter 

 the name of Phylloscopus newtoni. The differences between the two forms, as given by Mr. Gatke 

 (/. c), are as follows: — "The Siberian bird differs from that of India in general colour of 

 plumage, which in the former is suffused with a bright lemon-yellow, approaching and partly 

 surpassing that of P. sibilatrix, whereas the colour of the latter consists entirely of a dull 



brownish olive-yellow, verging in P. humei, in many instances, towards ashy grey In the 



Siberian bird the 2nd quill is of equal length with the 8th, in the Indian bird with the 10th ; in 

 the former bird the 2nd quill is only 9 millim. shorter than the point of the closed wing, in the 

 latter this difference amounts to 10 millim.; and whilst in the Indian bird the 2nd quill is of 

 equal length with the longest of the three posterior quills, it is in the Siberian from 6 to 7 millim. 

 longer. Further, in the Siberian bird the 3rd, 4th, and 5th quills are of equal length and form 

 the point of the closed wing, whereas in the Indian one such is the case with the 4th, 5th, and 

 6th quills, the third being 3 millim. shorter than these." 



So far as I can judge from the specimens I have examined, the differences between the 

 northern and southern forms are so slight, and the individual variations are so frequent, that I 

 cannot support Mr. Gatke's views, and do not, therefore; separate the species. Specimens from 

 India in my collection do not differ in general coloration from the Siberian bird, and in some of 

 the former the second quill equals the eighth, in others it is intermediate between the eighth and
