PALLAS'S Willow Wren (Phylloscopus proregulus, Pallas) is 

 an exceedingly rare visitor to the British Isles. An example 

 of this wren was killed on October 3ist, 1895, at Cley, in 

 Norfolk. It bears a great resemblance to Phylloscopus

 by the pale mesial line on the crown, and by the strikingly 

 pale yellow rump.
