BIRDS OF TENASSERIM. 21 



In younger birds the cheeks and ear-coverts are a darker grey ; 

 the occiput, nape, and sides of the neck are dark grey brown, 

 streaked with rufous ; the mantle is a nearly pure hair brown ; 

 the throat is much more tinged with buff; the breast is dark- 

 er and more mottled ; and the rusty rufous tinge is wanting on 

 the wing. 



In a still younger bird, the entire crown, occiput, 

 nape, and sides of the neck are mingled darker and lighter 

 brown, ferruginous and huffy white, and the cheeks are streak- 

 ed with white, and the ear-coverts are streaked paler. The fea- 

 thers of the breast are buffy white, with lanceolate rufous 

 brown shaft stripes, the brown of the abdomen is darker, and 

 the bars on the tail are much less conspicuous, while the bars on 

 the tibial plumes are almost heart-shaped. 



48 ter.— Butastur liventer, Tern. (2.) Descr. S. F., 

 V. 5 Ill, 31. 



(Tonghoo, Lloyd, Earns.) Kaukaryit, Hongtliraw R ; Amherst. 



Confined to the northern and central portions of the pro- 

 vince, and very rare except in the northernmost districts. 



[Extremely rare in Tenasserim Proper. I never saw it ex- 

 cept once at Kaukaryit, where I shot a male. Armstrong, 

 however, shot one for us at Amherst. I do not believe that it 

 occurs in the southernmost portions of the province, which I 

 have comparatively exhaustively worked. — W. D.] 



The following are the dimensions and colors of soft parts of 

 a male : — 



Length, 14'1 ; expanse, 35*0; tail from vent, 5-8; wing, 

 10-7 ; tarsus, 2-3 ; bill from gape, 1*2 ; weight, 12 ozs. 



Legs and feet gamboge yellow ; claws black ; one-third of 

 upper mandible and tip of lower mandible dull black ; rest of 

 bill, cere and gape, orange yellow ; irides pale yellow, facial 

 skin pale yellow ; eyelids orange yellow. 



52—Circuspygargus, Lin. — C. cinerarius, Mont. 



Blyth (B. of B., p. 61) gives this from Tenasserim; he 

 quotes no authority ; we have never seen it or heard of its 

 occurrence there, which seems to me doubtful. At the same 

 time it is right to note that Ramsay says, Ibis, 1875, p. 351, that 

 he thought he saw this species once in Karennee. 



53.— Circus melanoleucus, Forst. (6). S. E., Ill, 33 ; 

 V. 11. 



(Tonghoo, Rams.) Two days' march north of Paapoon ; Kedai Keglay; 

 Thatone ; Ngabeemah ; Moulmein. 



Very sparingly distributed throughout the province during 

 the cold season.
