From the plate I agree that Ornismya nattereri is a synonym of Augastes scutatus, and have added it to the Key.I am in a quandary regarding extinct birds. A good starting point is Hume & Walters 2012, Extinct Birds, which treated taxa which have become extinct within the last 700 years. More recent is the comprehensive list of Tyrberg, Lagerqvist & Jirle, 2017, Utdöda arter under Holocen fram til 1500, which deals with the Holocene (c. 11,000 BC) to 1500. I am inclined only to treat those birds which may be considered to have been extant in the modern period (e.g. reliable contemporary accounts, descriptions and illustrations, remains found in  middens). However, even though most of them are not in HBW & BLI Illustrated Checklist, for the sake of completeness I will enter all the names found in Hume & Walters 2012 and in Tyrberg et al. 2017, in the Key in due course (when I have sorted out the living birds!)</blockquote>
