BOGDANOW'S GREY SHRIKE.
Lanius przewalskii Bogd., Wur. der Buss. Faun., p. 147 (1881) (Tashkent). Lanius homeyeri. Blanf. & Oates, i; p. 461.
Vernacular names. None recorded.
Description. Similar to pallidirostris, but generally paler; the forehead, rump and upper tail-coverts much whiter and the bases of all the tail-feathers white. The secondaries generally have more black and less white than in the Allied Grey Shrike, but this character is very unreliable and some individuals have the greater part of these feathers white.
Colours of soft parts. Iris brown ; bill dark horny, paler on the mandible and base of maxilla, specimens killed in the breeding-season all have the bill black; legs and feet dark horny-brown to black.
Measurements. Wing 108 to 122 mm.; tail 106 to 118 mm.; tarsus about 30 mm.; culmen 18 to 19 mm.
Distribution. Turkestan to Samarkand and Ferghana, Kuldja, Tian Shan, East Turkestan to the Gobi Desert. In Winter to South Russia and to Gilgit.
Nidification. The only clutch of eggs I have seen of this Shrike are like those of L. e. excubitor and measure about 26.0 x 19.4.
Habits. Those of the species.
