BIRDS OF UPPER PEGU. 135 



of one race in the very centre of the area of the other by saying 

 that these are mere seasonal migrants. It does not much matter, 

 perhaps, how the thing- is explained ; the facts are the same. 



484.— Pratincola leucura, Blyth. 



A single specimen procured at Boulay is quite identical with 

 birds from Tipperah, but they are rather darker and brighter- 

 colored, and perhaps a shade smaller, than those from Sindh ; but 

 the difference is not sufficient to warrant specific separation : 

 indeed, is not so great nearly, though it is of the same kind, as 

 that between rubicola and indica. This species is only to be 

 foimd in the plains about paddy lands. 



486.— Pratincola ferrea, Hbdgs. 



Mr. Oates procured a single specimen of this Chat — a female — 

 at Prome, on the 23rd November. He gives the following 

 dimensions : — 



Length, 5*95 ; expanse, 6*4; tail, from vent, 2'5 ; wing, 2 # 25; 

 bill, from gape, 0-72 ; tarsus, 0*92. 



The bird occurs, as we already know, in the Arracan Hills, 

 although whether as a permanent resident or a seasonal visitant 

 is uncertain, and it now appears that in the winter, at any rate, 

 it straggles down to the plains of Upper Pegu. 



500.— Euticilla aurorea, Pall. 



A single specimen, a female, was sent me by Captain Feilden, 

 who obtained it in the cold-season in the neighbourhood 

 of Thayetmyo. It was the only one, he said, that he had 

 seen. 



512.— Calliope camtschatkensis, Gm. 



Of this species also Captain Feilden sent a single specimen, 

 killed near Thayetmyo. 



530.— Orthotomus longicaudus, Gm. 



Thayetmyo specimens are identical with those from various 

 parts of India. 



Mr. Oates remarks : " This is a common bird in the plains, 

 and possibly also on the hills, though I did not observe it on 

 the latter. I found the nest of this species containing young 

 birds in the Thayetmyo cantonment on the 1 2th August. The 

 irides are reddish yellow ; the eyelids, grey ; but their edges, reddish 

 yellow; the upper mandible, dark horny; the lower, pale fleshy; 

 the inside of mouth, pale whitish fleshy ; legs, rufous fleshy ; 

 claws, pale brown. The length varies very greatly, according
