I agree with cohazard. MY references show that P.bichir was first described in 1802 from the Egyptian Nile, by a frenchmen, probably with Napolean's invasion force!
The genus Polypterus was first described by Geoffroy Saint-Hilaire in 1802 while he accompanied Napoleon's invading army into Egypt. Cuvier was claimed to have said something along the lines of 'The invasion of Egypt was worth it if only for the discovery of these fishes'.
