The Black-browed Warbler, Jerd.

Coloration. Two broad black bands, one on either side of the crown, reaching to the base of the bill, and enclosing an olive-green stripe ; sides of the head up to the black coronal band yellow tinged with olive; a conspicuous yellow ring round the eye ; the whole lower plumage bright yellow ; the whole upper plumage olive-green ; wings, coverts, and tail brown, edged with olive-green, the greater coverts also tipped with yellow; the two outer pairs of tail-feathers white on the inner webs, the third pair occasionally with some white.

Upper mandible deep brown ; lower mandible pale yellowish brown ; legs and feet pale brownish yellow ; iris hazel (Hume).

Length about 4.5; tail 1.8; wing 2.1; tarsus .75 ; bill from gape .55.

Distribution. Throughout the Himalayas from the valley of the Sutlej river to Bhutan, and along the Assam valley to Dibrugarh. This species also occurs in the Khasi hills, Sylhet, Cachar, and Manipur. Blyth records it from Arrakan, but he may have mistaken for it C. tephrocephala, which at that time had not been discriminated.

I cannot find any specimen of this species from the plains of India, but Blyth states that it is common near Calcutta in the cold season, and McMaster records it from Kamptee in the Central Provinces and Chikalda in Berar.

The next two species have been confounded by almost all writers except Hume and Brooks. The larger and paler form is the species to which Hodgson, judging by his types which are still in the British Museum, gave the name of xanthoschistus. It is also the species to which Blyth applied the name of albosuperciliaris.

The smaller and darker form was without a distinctive term till Brooks applied to it the name of jerdoni. It is also found in Nepal, and is the bird referred to by Scully (l. c.) as Abrornis xanthoschistus. Some of his specimens are in the British Museum, and I have been able to examine them *.

There is an extraordinarily fine series of both species in the British Museum now, and the geographical distribution of each can be traced with ease. 1 understand Brooks to say (I. c.) that there are three species of this type of Cryptolopha, but I am unable to distinguish more than two from the series I have examined.

Both species are figured in 'Lahore to Yarkand.' The upper figure named A. xanthoschistus is rightly so called. The lower figure named A. albosuperciliaris should be C. jerdoni.
