On the bibliography of a late eighteenth-century German work on natural history and an early record of Leuciscus meidingeri Heckel, 1852 (Pisces, Cyprinidae) in the river system of the Upper Danube on 6th APRIL 1786

The bibliography of a hitherto inaccurately described anonymous eighteenth-century popular German work on natural history is given, dealing with mammals, birds, fishes, amphibians and reptiles. As an addendum to this work the publisher has given an engraving of an unknown fish from the river Lech, river system of the Upper Danube. The fish could be identified as the cyprinid Leuciscus meidingeri Heckel, 1852. The observation of the species was made 66 years before its recognition as a new species by Heckel.
