equal to or shorter than the sixth. Length, 4'5 ins. Wing, 

 2*35 ins. Tarsus, "8 in. 



Siberian Chiffchaff. Phylloscopus tristis Blyth. 



The Siberian Chiffchaff is now known to be a regular autumn 

 visitor to the Shetlands and Orkneys, where it has wintered ; 

 it has also been found on the Isle of May. Its recognition as 

 a British species is due to the investigations of Mr. Eagle 

 Clarke. It breeds in eastern Europe and Siberia, and is known 

 to winter in India. Dresser describes it as smaller, browner and 

 whiter (on the under parts) than P. collybiia ; Mr. Witherby 

 says that it is "easily distinguished by its very brown upperside, 

 grey underside, brownish flanks and bright golden axillaries." 

 The skins I have examined support Mr. Witherby ; they are 

 distinctly greyer beneath than those of K)ur Chiffchaff, and the 

 axillaries Hghter. Mr. H. G, Alexander, Miss Turner and 

 others watched a Chiffchaff on several days in November and 

 December, 19 13, in Kent, which they believe was referable to 

 this species. They particularly noticed a distinctive plaintive 

 call, as well as the characters described above. Length, 4 ins. 

 "Wing, 2*3 ins. Tarsus, '8 in.

 in September, 1896, in Lincolnshire. It is greener than the 

 Willow-Wren, and less yellow on the under parts, and there is 

 a yellowish white wing-bar. Length, 4*25 ins. WMng, 2*25 ins.
