Hodgson's description of this bird is from specimens from Nepal, whilst Brooks describes Cryptolopha (= Seicercus) jerdoni as the Eastern representative of xanthoschistus. This latter bird is, however, the true Eastern form, and Brooks compared his specimens with Kashmir birds instead of Nepal ones as he should have done. His name jerdoni therefore becomes merely a synonym of xanthoschistus. The next name applied to the Western race is that of Abrornis albosuperciliaris of Adams, used in his "List of the Birds of Kashmir," P. Z. S. 1859, p. 1S2, and applied to this form by Jerdon in his ' Birds of India," ii p. 202, and sufficiently described therein. The Eastern form will therefore bear Hodgson's name Seicercus xanthoschistus xanthoschistus, whilst the Western form must be called S. .v. albosuperciliaris.
