The Himalayan, Magpie, Jerd.
Coloration. Resembles P. rustica, but is much larger with a longer wing and shorter tail and with the rump entirely black.
Length about 21; tail 11.5 ; wing 10 to 10.5; tarsus 2.1 ; bill at front 1.4 to 1.0.
All the species of Pica have a band of white or grey across the rump except the present form and P. mauritanica, which is found in Spain and N. Africa. Of P. bottanensis there are some thirty specimens in the British Museum and they all agree in having the rump entirely black, in their large size, short tail, and long
Distribution. The higher parts of Bhutan, Native Sikhim, and Chinese Tibet. There is no evidence that P. bottanensis occurs in Nepal. There is a skin in the British Museum said to have been collected in Kumaon, but I doubt the correctness of this locality.
