ACANTHOPKEUSTE. 413 



As the summer goes on the wing-bars get worn away and the 

 upper one is sometimes absent. The lower plumage gets whiter 

 aucl the upper plumage duller. After the autumn moult the wing- 

 bars are very conspicuous and the underparts become suffused with 

 deeper yellow. 



Upper mandible dark brown, the edges and tip yellow; gape and 

 basal half of the lower mandible orange-yellow, terminal half dusky; 

 mouth bright orange-yellow ; iris dark brown ; legs flesh-colour, 

 tinged with yellow ; claws yellowish horn-colour. 



Length 4-8 ; tail 2 ; wing* 2-7 ; tarsus -8 ; bill from gape -68 ; the 

 second primary is intermediate in length between the fifth and 

 sixth, and is sometimes equal to the sixth ; the first primary is very 

 small, measuring from '3 to '45 inch in length. 



Distribution. A fairly common winter visitor to Southern Pegu 

 and Tenasserim, arriving about the middle of September. Hume 

 met with it at Aimole on the eastern hills of Manipur in the middle 

 of April. It has been procured in the South Andaman, from 

 which locality 1 have examined two specimens. 



It has a wide range in winter through South-eastern Asia, and 

 it summers in Northern Asia.

Coloration. Upper plumage and the sides of the neck bright 

 yellowish green; wing-coverts brown, edged with yellowish green; 

 the median coverts faintly, the greater coverts distinctly tipped 

 with pale yellow ; wings and tail brown, narrowly edged green, 

 the outer tail-feathers margined with white interiorly ; lores and

 Calcutta. Its summer-quarters are not known with certainty, but 

 they are not unlikely to be in Kashmir and the higher levels of the 

 Himalayas.
