What is the provenance of the specimen of the Hippotragus leucophaeus (Pallas, 1766) (Bloubok, Bluebuck, Blue Antelope) in the Muséum national d'Histoire naturelle in Paris? This article argues that new archival evidence, an examination of the specimen, and a critical re-examination of claims by Mohr suggest that the specimen came from the French traveller and ornithologist François Levaillant (also written Le Vaillant) and not from a specimen supplied by Gordon that Mohr and Rookmaaker speculated was taken from the Stadholder of Holland's collection in 1795.
