Abstract
The 1824 expedition to Lebanon by Wilhelm Hemprich and Christian Ehrenberg resulted in the description of at least 28 bird species new for science. Despite its importance, however, this collection has never been fully studied or published. We used manuscripts, catalogues, and specimens archived at the Museum fur Naturkunde (ZMB), Berlin, to identify the type specimens, revise nomenclatural and (where appropriate) taxonomic status of species described on the basis of Hemprich and Ehrenberg's material,and determine type localities and collection dates of these taxa.
