Panthera tigris sudanensis
Panthera tigris sudanensis is a scientific name for a tiger subspecies that was proposed by Paul E. P. Deraniyagala in 1951 based on a tiger skin seen in a Cairo bazaar. When Deraniyagala asked the shop owner for the origin of this specimen, he was told that the animal was shot in Sudan. As Vratislav Mazák wrote in 1980, it was either a joke or the seller felt obliged to be polite and answer the question, whether with truth or invention. Deraniyagala took a picture of the specimen's skin, which according to some scientists looked like a Caspian tiger (P. t. virgata) given the pattern of its stripes. It was most likely smuggled from Iran or Turkey to Egypt. As Mazák wrote, "the situation is half-humorous, half-ironic."
