COMMENTS: The specimen collected on 12 July 1815 at Renthendorf was designated the lectotype by Hartert (1918a: 26) , who added that Brehm had described advena from ‘‘exceptionally pale, partially juvenile, specimens.’’ No other specimens from Renthendorf that came to AMNH were collected early enough to have been used by Brehm in his description of this form.
