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 ist, and full details have since 

 appeared in 'The Zoologist' for 1S97, pp. 5-12; 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 

 A^ellow-browed Warbler, shot near Newcastle in 1838, was supposed 

 to be this species until 1S63, when Swinhoe pointed out the error, 

 and Hancock subsequently rectified his identification (' Ibis ' 1867, 

 p. 252). On October 6th, 1845, Glaus 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. Giitke, 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
