Som Graham påpekar visar illituerna mer fysisk likhet med Chthonians .
Chthonians (/ˈθoʊniənz/ from Greek: chthon, "earth") are fictional creatures in the Cthulhu Mythos. Chthonians as name of the species is the creation of English horror-fiction writer Brian Lumley and was first featured in his short story "Cement Surroundings" (1969)—though the creature never made a direct appearance. The chthonians had a more prominent role in Lumley's novel The Burrowers Beneath (1974), whose title was taken from one of the stories said to have been written by Robert Blake in Lovecraft's "The Haunter of the Dark."
