Panurus biarmicus raddei Pražák

Panurus biarmicus raddei Pražák, 1897e: 288 .

NOW. Panurus biarmicus russicus (C.L. Brehm, 1831) . See Hartert (1907a: 405).

Holotype (lost): “ad. 3” [= juv.], collected by Gustav Radde (1831–1903) on 22 April 1886 (NS) at “Astara” [= Astara, Azerbaijan; 38.46°N, 48.88°E]. See Radde (1887: 477).

Remarks. Pražák (1897e: 288) based this form on a specimen erroneously described by Radde (1887: 477– 478) as an adult male, although the plumage agrees with that of a juvenile bird (see also Hartert 1907a: 405). The specimen was in the Radde Collection, but its current whereabouts is unknown.
