WILLOW-TITMOUSE [No. 98, British Willow-Titmouse; 

 No. 99, Northern Willow-Titmouse]. A close ally of the 

 ' MARSH-TITMOUSE, first identified as a British bird by 

 Mr. Hellmayr in 1900, although the Continental form 

 (which has been identified once in our own islands) was 

 distinguished as long ago as 1843 by De Selys-Longchamps. 

 In Scotland, the British Willow-Titmouse appears quite 

 to replace the Marsh-Titmouse. 



WILLOW-WARBLER j[No. 122, WILLOW-WARBLER; 

 No. 123, Northern Willow- Warbler]. Willow- Warbler ap- 

 pears in Yarrell (1843). It occurs in Pennant (1766) as 

 Willow Wren, but by most authors from Edwards to Fleming 

 (1842) it is termed Yellow Wren. Macgillivray calls it the 

 " Willow Woodwren." It is the " Regulus non cristatus " 

 of Willughby. The Siberian form has been identified in 

 our islands on migration.

WILSON'S PETREL [No. 322]. The name is found in Jenyns

 in honour of Wilson the American ornithologist, who first 

 figured it, but without being aware of its distinctness from 

 the STORM-PETREL.
