and Corrections to the “ Birds of Kohat.” 621 
the young have to be fed. The majority appear to breed 
in immature plumage—only two were observed in the glossy 
black dress with orange bill of the adult. I have sent a 
nestling and a bird of the year during its first moult to 
the British Museum. 
[812.] Ptyonoprogne obsoleta. 
Common in March in the craggy hills of South Kohat. 
A few individuals were in pairs, so the bird may possibly 
breed there. 
[838.] Motacjlla citreoloides. 
I can confirm my note about the nesting of this species 
in immature plumage. This year I was in its breeding- 
grounds a month earlier and came across a good many nests. 
Only about half of those breeding were in full plumage. 
The remainder were of two forms :— 
(1) Grey above, with black feathers here and there; 
supercilium and under surface yellowish-white. 
(2) Dark grey above with some black feathers; head and 
under surface deep yellow, sullied on the flanks and crown. 
I have sent two examples, namely a nesting pair, the male 
of type (2) and the female of type (1), to the British Museum. 
[851.] Anthus spipoletta. 
In my list ( f Ibis/ 1909, p. 244) under No. [851] appears 
an enumeration of six specimens under the name Anthus 
spipoletta and of three under Anthus coutellii; under the 
latter name, however, two specimens (Nos. 646 and 647) are 
mentioned again, though they had appeared already as 
Anthus spipoletta. Dr. Hartert has kindly examined these 
Pipits for me, and he informs me that, in his opinion, they 
belong neither to typical A. spipoletta nor to A. coutellii , but 
to the Central Asiatic form which he calls Anthus spinoletta 
blakistoni ( cf '. Hartert, Vog. pal. Fauna, i. p. 282). As to 
numbers 622, 632, and 636, he is quite sure that they are 
typical A. blakistoni , while Nos. 387 and 568 are too much 
worn and too dirty to be named with certainty, but there is 
no reason whatever to doubt their belonging to A. blakistoni
