brown, with wide reddish edges ; the yellow tips of the large wing-coverts 



form a band on the wing. Under wing-coverts grey, with a rose shade ; the i 



joint of the wing rose-colour. The four central tail-feathers dark brown or \ 



blackish ; two of them are edged broadly with yellow ; the two remaining . 

 ones have sometimes crimson outer webs. The other quills are light 



crimson, with white tips on the three exterior feathers of each side. Under \ 



tail-coverts rose-colour ; upper coverts dark reddish brown, with wide yellow ' 



edges. i 



Female. — Above, the same colour as the male ; but the underparts of the I 



body are yellowish white (occasionally with a rose tint), and with black i

colour ; but in spring the outer feathers are entirely orange- colour, and the - 



third is of a mixed colour between orange and dark reddish brown on the J 



inner web ; the joint of the wing is also orange. i

 Pylzoff, who has been so useful to our expedition by his untiring energy. 



We first met with U, pylzowi on the sources of the river Tetung, during 

 the autumn migration, early in October 1872; and in the spring of the 

 following year we again fell in with these bh'ds there, early in April ; and, 

 as before, they kept singly or in small companies in plains and valleys near 

 rivers, usually about the low thick bushes of Potentilla tenuifoUa, 



Then, again, during our stay of more than a month in the mountains 

 south of the central course of the Tetung, we did not meet with these birds, 

 nor in the preceding year, and found them breeding only towards the end of 

 May, in the alpine regions of the mountain north of the Tetung. Here, as 

 also in the former locality, the birds kept almost exclusively in the bushes of
