A CONTRIBUTION TO THE OENITHOLOGY OF NEPAL. 315 



whole tliroat and cLin black, a small spot or two of white 

 only beiug visible on the latter region. 



Immature examples of levcopsis are not easily distinguished 

 from birds of this species in winter garb ; the only point that 

 is then available for separating them is, as pointed out by Mr. 

 Brooks, the superior amount of white on the wing of leucopsis. 



I have called my birds alha and not dukhunensis, be- 

 cause the general opinion (Hume, Dresser, Blanford, Seebohm) 

 seems to be that there is no specific difference between the two 

 forms ; moreover, my specimens exhibit very little white on the 

 wing, and I have lately seen a young specimen, shot within 

 Indian limits, with the forehead, sides of neck, and throat 

 strongly tinged with pale yellow — a point considered by Mr. 

 Brooks to be distinctive of alba. 



This Wagtail is common in the valley of Nepal from October 

 -to nearly the middle of May. 



591 9^wa«.-— Motacilla ocularis, Swinh. 



? Female, Valley, 7th May. — Length, 7-6; expanse, 11; 

 wing, 3-5 ; tail, 3*65 ; tarsus, 0-95 ; bill from gape, 0'67 ; bill 

 at front, 0*44 ; closed wings short of tail, 2*25. 



Back pure grey ; a black patch on the hind head, and from 

 the centre of this a black line passes across the ear-coverts 

 through the eye to the base of the bill ; a black patch on the 

 throat and breast ; the point of the chin white. 



Only one specimen of this Wagtail was obtained in the val- 

 ley of Nepal in May, when it was probably passing through 

 on the way to its breeding haunts. I have compared it with 

 specimens of ocularis in Mr. Hume's museum, and there can 

 be no doubt that it must be referred to that species. As 

 this is last of the Motacillas which I have to notice, I may 

 mention that no Wagtail of any kind is ever seen in the 

 Nepal Valley from the middle of May to the beginning of 

 September.

 tarsus, 075 to 0-8 ; bill from gape, 0-63 to 07 ; bill at front,
