PALLAS’S WILLOW-WARBLER. 
PHYLLOSCOPUS PROREGULUS (Pallas). 
On October 31st, 1896, a specimen of this small Warbler was shot 
by Mr. Ramm, amongst the long grass by the sea-wall at Cley-next- 
the-Sea, Norfolk, and proved on dissection to be a female, probably 
adult. It was recorded by Mr. T. Southwell (‘Zoologist,’ 1896, 
p. 467), exhibited by Mr. Dresser at a meeting of the Zoological 
Society of London on December rst, and full details have since 
appeared in ‘The Zoologist’ for 1897, pp. 5-123; as well as in the 
Tr. Norw. Soc., vi. pp. 210-290, from Mr. Dresser, who has added 
valuable notes on other rare Warblers. 
Pallas’s Warbler was for some time known to us by Gould’s trivial 
name of “Dalmatian Regulus,” commemorative of the reported 
place of capture of the first European example, in 1829. Hancock’s 
Yellow-browed Warbler, shot near Newcastle in 1838, was supposed 
to be this species until 1863, when Swinhoe pointed out the error, 
and Hancock subsequently rectified his identification (‘ Ibis’ 1867, 
p. 252). On October 6th, 1845, Claus Aeuckens, of Heligoland 
(then a lad), killed a small Warbler with a stone, completely 
crushing it, but he brought an undamaged wing and “a portion of 
the lower back with part of the lemon-yellow plumage still adhering to 
it” to the late H. Gatke, and in 1879 comparison with a Siberian 
skin of Pallas’s Warbler showed that the wanderer to Heligoland 
was that species. Another was watched at short distance by 
Aeuckens and his nephew, on October 2gth, 1875, but the bird was 
sheltering under the edge of the cliff from a violent east wind, and
