Scops scops taczanowskii Pražák

Scops scops taczanowskii Pražák, 1891: 19 [Manuscript name, cited after Pražák, 1897e: 442.]

Remarks. Pražák (1897e: 442) stated that he described this form in his previous book ( Pražák 1891: 19), which, however, had never been published. Pražák (1897e: 442) withdrew his S. s. taczanowskii, explaining that the separation of the form “mir aber jetzt zu kühn erscheint” (“seems too daring to me now”). Scops scops taczanowskii Pražák, 1891, is thus a manuscript name without standing in zoological nomenclature. Pražák’s (1897e: 442) reference to Taczanowski (1882: 149) is irrelevant from the nomenclatural point of view.
