Charles de Souancé
Charles de Souancé (2 May 1823 – 23 January 1896) was a French ornithologist and a purser in the French Navy, more precisely "Commissaire de la Marine". He made many studies on the ornithological collection of his  uncle François Victor Masséna and described several  new species of parrots (Psittacidae) in the scientific journal Revue et Magazin de Zoologie. A subspecies of  the maroon-tailed parakeet, Pyrrhura melanura souancei, is named for him. Published works
