Adult Male. Similar to P. superciliosus, but easily dis- 

 tinguished by the yellow rump, in strong contrast to the 

 greenish back. Like P. supertiliosus, it has a couple of yellow 

 wing-bars, as well as a light yellowish streak on the crown ; 

 " upper mandible dark-brown, the lower one orange nearly to 

 the tip ; legs brown ; feet yellowish." Total length, 4*5 inches ; 

 culmen, 0-45 ; wing, 2-3; tail, 1-65; tarsus, o'8. 



Adult Female. Similar to the male. Total length, 3-6 

 inches ; wing, i -9. 



Seebohm says that the winter plumage is scarcely distinguish- 

 able from the summer plumage, but the autumn livery is more 

 brilliant than that of spring. In summer, the yellow of the 

 mesial line on the crown, eye-stripes, wing-bars, and rump, 

 becomes paler by abrasion, the pale tips to the quills dis- 

 appear, and the broad edges to the innermost secondaries 

 become narrow. Otherwise, he says, the changes from spring 

 plumage are very slight. 



Range in Great Britain. A specimen of this Willow- Warbler 

 was shot at Cley, in Norfolk, on the 3ist of October, 1896, by 

 Mr. E. Ramm. 



Range outside the British Islands. In Heligoland this species 

 is believed by Gatke to have occurred at least twice. Its home 

 is in Eastern Siberia and the Himalaya Mountains, and it visits 

 the neighbourhood of Orenburg in autumn, and winters in 

 Tenasserim and in Southern China. 



Habits. The present species is described as having a very 

 powerful note. Mr. Styan describes it as a " loud Canary-like
