NOTES ON SIKHIM BIRDS. 231 



0. (1) 13. UrOCissa flavirostris.— Out of U specimens five 

 have those portions of the lower plumage and tail, Avhich are white in 

 the ordinary specimens, of a more or less rich fulvous tint, and all of 

 these came from the eastern side of the Tista and the Upper Lacchhen 

 Valley, viz. — 



1 male and 1 female from Samdong LaccHhen ... November, 1891. 



„ ,, „ Labah June, 1892. 



1 male from Fyumgang April, 1891. 



From Memphhuk, 13,000, below the Tangkar La, in October, was 

 got an aged female with a horny-6/fflc/: bill. 



0. 26. GarrulUS bispecularis.— Its range is very much 

 higher than given by Oates. It does not seem to be known in Sikhim 

 below 7,000, and is usually found in the pine forests — 11,000 to 

 13,000. 



0. 50. Conostoma semodium.— The English name is 

 rather a misnomer as the bill is dull yellowish light orange, and Oates' 

 woodcut is somewhat misleading as there is no dark colour post- 

 orbitally. 



0. 53. Suthora uniCOlor.— Sides of head with pale 

 streaks. 



0. 54. S. humii.— Bill is pale yellow. 



0. 65. Dryonastes CSerulatUS.— In all my eleven speci- 

 mens the post-orbital region is lightly streaked. It extends up to 

 below the Donkya to 16,000, and is therefore likely to be met with in 

 Tibet. 



0. 69. Garrulax leuCOlophus.— Tail is obscurely barred. 



0. 72. G. pectoralis. — Two [1 male, Lingmo, November, 

 and one female, Nimbong, (Br. Bhutan) January] have the chin and 

 throat anterior to the gorget almost unsullied white, the rest have 

 this region fulvous. One female from Rathong (4,000) had the upper 

 back bordering the nachal collar fringed with white. Another (a 

 female, Rungeet, April, 1891) had vinaceous-slaty instead of white 

 on tail, under-surface, and supercilium, and no fulvous collar. 



0. 73. G. moniliger. — Have ear- coverts black with whitish 

 centre. 



0. 76. G. albigularis. — In regard to the question of location, 

 2 are from Gurubathau, British Bhutan — with reference to Mr. Oates' 

 note that he had not seen any from Bhutan. Not very common. 



0. 80. lanthOCincla rufigularis.— Not very common. 

 My three specimens from (1) Tsunthang, Tista valley, 0,000; Singla, 

 A^cjoa/ Frontier, 10,000, in April; and Phema, 7,000, in March, have not 

 the exceptional colouring noted by Oates as characteristic of Nepal,
