conferred by Pallas at an earlier date. As will be seen, however, 

 it had to disappear for a time from the British list, as it was 

 further discovered that Mr. Hancock's bird had been wrongly 

 determined, and belonged to a closely allied species, the Mota- 

 cilia superciliosa of Gmelin, the Yellow-browed Warbler. Mr. 

 Swinhoe pointed out the distinctive features of the two birds in 

 the ■ Proceedings' of the Zoological Society for I860 (" Catalogue 

 of the Birds of China"), p. 297, and further stated that Mr. 

 Hancock's specimen was specifically identical with examples of 

 the Yellow-browed Warbler obtained in China. Thus we lost 

 the Dalmatian Warbler as a British bird, and obtained the 

 Yellow-browed Warbler in its place. 



In the ' Ibis ' (1867, p. 252) Mr. Hancock corrects his previous 

 determination of the bird killed by him in 1838, stating in what 

 respects he found it to differ from Gould's Reg uhts modesties ; and 

 Mr. Gould does the same in the second volume of his 'Birds of 

 Great Britain' (1873), when referring to the confusion which had 

 arisen in consequence of Mr. Hancock's bird having been regarded 

 by many authors as specifically identical with that received from 

 Baron Feldegg, and figured by him in the ' Birds of Europe ' 

 under the impression that it was a newly discovered species. It 

 may be mentioned here that Phylloscopus superciliosus has sub- 

 sequently been met with in Britain in some eleven instances, one 

 of which was on our own coast at Cley on Oct. 1st, 1894. Having 

 thus disposed of this puzzling subject, we may turn to the bird 

 under immediate consideration. 



The next and only other occurrence of Pallas's Willow 

 Warbler (Dalmatian Warbler) in Europe, until the Norfolk 

 specimen, so far as I know, is that mentioned by Herr Giitke in 

 his * Birds of Heligoland' (p. 293). On Oct. 6th, 1845, Claus 

 Aeuckens, one of his most devoted collectors, then a youth, and 

 not having arrived at the age when he might be trusted with 

 powder and shot, armed only with " a hunting-bag full of rounded 

 pebbles, which he knew how to employ with the most astonishing 

 dexterity," killed a small Warbler with one of his stones " as it 

 was flying round the face of the cliff, and completely crushed it 

 against the rock." Aeuckens noticed that the bird was an 

 unusual one, and brought a wing which had remained undamaged, 

 " with a portion of the lower part of the back with part of the
