2515. Certhia himalayana, Vig. (P. Z. S. 1831, p. 174), is easily distinguishable by its very distinctly barred 
tail and dark upper parts. It is only found in the North-western Himalayas. 
2516. Certhia nipalensis, Hodgson (J. A. 8. xiv. p. 580), very closely resembles C. discolor, but differs in 
having the flanks and lower tail-coverts ferruginous, and the underparts generally greyer; the head 
and back are also darker and less rufous in colour; the rump, however, is much more rufous in tinge. 
It is found, according to Jerdon, in Nepal, and on some of the higher mountains of Sikkim. 
2517. Certhia discolor, Blyth (J. A. 8. xiv. p. 580), approaches nearest to Certhia familiaris, but may be at 
once distinguished by its much longer tail. It has the upper parts dark, and the upper tail-coverts very 
rufous, and, except for its long tail, very closely resembles some of the Guatemalan specimens collected 
by Mr. Salvin. It inhabits Sikkim. 
Of Certhia himalayana 1 have examined four specimens in Lord Walden’s collection, one 
in that of Captain Elwes, and one in my own collection; of C. nipalensis, one in Lord Walden’s, 
and one in Captain Elwes’s collection; and of C. discolor, four in the collection of Lord Walden, 
and one in that of Captain Elwes.
