282 31 R. H. E. DRESSER ON PALLAS’S WILLOW WARBLER 
judge from the characteristic call-note it was observed earlier, 
between the 28th of September and 4th of October in the woods 
on the other side of the Ural. In 1888 it again appeared near 
Orenburg, though in smaller numbers, and on the 23rd of 
October a flock of five were seen, and one shot, at the village of 
Neshenka. It has also been recorded from the Upper and Central 
Lena, and on the Witim. The other records of its occurrence in 
Europe are as follows : — One by Gould (B. of Eur. vol. ii. p. 149), 
of a male sent to him by Baron Feldegg of Frankfort, said to have 
been shot in Dalmatia in 1829; and according to Mr. Giitke 
(Yogelw. Helgoland, p. 304), one was killed by Aeuckens in 
October, 1845, and another seen but not obtained in October, 1875, 
on Heligoland. 
This Warbler was first described by Pallas in 1S11 (Zoogr. 
Boss. As. vol. i. p. 499), from Siberia, and in 1837 Gould (I. c.) 
redescribed it from a specimen, said to have been obtained in Dalmatia, 
under the name of Regulus modestus. In 1838 (Ann. Hat. Hist, 
vol. ii. p. 310) the late Mr. John Hancock recorded under the 
name of Regidus modestus, Gould, the occurrence of a Warbler, 
which was shot on the banks near Hartley on the coast of 
Northumberland, on the 2Gth of September, 1838, which, how- 
ever, was subsequently (‘Ibis,’ 18G7, p. 252) shown by him to be 
the Yellow-browed Warbler, Pliglloscopus superciliosus (Gmel.), 
and not the present species, this being the first occurrence in Great 
Britain of that species, which however has been subsequently 
obtained here on at least eleven occasions. 
The range of Pallas’s Willow Warbler in Asia is, as stated in 
my supplement to the ‘Birds of Europe,’ p. 74, very extensive. 
It does not appear to have been recorded from Western Siberia, 
but is not uncommon throughout Eastern Siberia. The references 
to its occurrence near Lake Baikal are tolerably numerous. 
Schwedoff observed it on passage in the public gardens at Irkutsk 
and on the banks of the Uschakovka, about forty versts from that 
town, and his identifications have been verified by Dr. Severtzolf. 
According to Dybowski it is not rare at Kultuk, but does not 
appear to breed there, as nests were only found at Petrovsk, 
beyond Lake Baikal, on the left bank of the Sselenga ; a specimen 
obtained by him is in the British Museum. Mr. Mollcsson records 
this Warbler on passage from near the town of Troitzkossavsk,
