Cinclus bilkevitchi Zarudny

Cinclus bilkevitchi Zarudny, 1902: 57 (Altai, Tau Tek­

ele).

Now Cinclus cinclus leucogaster Bonaparte, 1850 . See

Hartert, 1920: 504, Tyler and Ormerod, 1994: 10, and

Brewer and MacKay, 2001: 200.

HOLOTYPE: AMNH 573429 , adult male, collected at Tau­Tekele, Altai Mountains, on 16 June (not July) 1894 (Russian calendar), by S.I. Bilkevitch. From the N.A. Zarudny Collection via the Rothschild Collection.

COMMENTS: Only one specimen is mentioned in the original description, and only one Zarudny specimen of bilkevitchi came to AMNH with the Rothschild Collection. It is of the dark morph of C. c. leucogaster , discussed by Hartert (1910a: 796) and Vaurie (1951a: 11–15) but not mentioned by Tyler and Ormerod (1994) or by Brewer and MacKay (2001). The belly is entirely dark and the throat and breast feathers have lighter bases, giving these areas a paler appearance.
