Now Poecile montanus borealis (Sélys-Longchamps, 1843) . See Snow, 1967c: 76 , and Gosler and Clement, 2007: 712–713 . LECTOTYPE : AMNH 682238 (Kleinschmidt no. 53), adult male, collected in the Carpathian Mountains ( 5 Karpathen, as on label), Galicia , southwestern Poland , on 6 April 1852 , by Count Wodzicki. From the Brehm Collection via the Rothschild Collection. COMMENTS: In the original description, Brehm did not designate a type or indicate how many specimens he examined. Kleinschmidt (1897: 88) listed the type of assimilis as his no. 53 in the Brehm Collection, thereby designating the above specimen the lectotype . I did not find other specimens labeled assimilis by Brehm. Gosler and Clement (2007: 711) commented: ‘‘[ Poecile ] normally treated as feminine, but no evidence in original description or elsewhere justifies this, so genus is masculine by default.’’ See David and Gosselin (2008: 19) for explanation of derivation of Poecile .
