537. Cyanosylvia suecica pallidogularis

(537) Cyanosylvia suecica pallidogularis (Sarudny).
THE EASTERN RED-SPOTTED BLUE-THROAT.
Cyanosylvia suecica pallidogularis, Fauna B. I., Birds, 2nd ed. vol. ii, p. 85.
The various races of C. Suecica have recently been reviewed by Tugarinov. (Ann. Du Mus. Zool. de 1’Acad. Des Science de 1’U.R.S.S., 1928). He admits eleven Asiatic races and, of these, it is probable that more than the number of subspecies hitherto accepted as occurring in India do visit it during the cold weather. All Osmaston’s and Ludlow’s skins of breeding birds taken by them on their nests in Ladak prove to be abbotti, as suggested by Ticehurst (Journ. Bomb. Nat. Hist. Soc. vol. xxxi. p. 493, 1929). It is now also definitely certain that all these birds must be treated as races of the one species, Cyanosylvia suecica.
It is doubtful if pallidogularis or any of the pale forms breed within our limits, but there is one May specimen and one August specimen of pallidogularis in the British Museum collection, obtained at Gilgit, which may have been breeding birds.
Both nests and eggs differ in no way from those of the next bird, and eggs taken by Niginoff at Naryn-Prechervalskij average about 19.3 x 14.1 mm.
