Sniilor the Eighth was an individual of unknown species, possibly a leader of some kind, for whom a sphinx monument was made. Before joining the crew of the USS Voyager, Neelix went treasure-hunting in the catacombs beneath the Lost Sphinx of Sniilor the Eighth. He didn't find any gem-studded latinum, but he narrowly avoided a bottomless pit filled with flesh-eating marrow-wyrms. (TOS novel: No Time Like the Past)
