Warihu is a named spirit-being of San Cristoval recorded in C.E. Fox's account of the island's religion, belonging to the same complex of figona and adaro beings that Codrington documented for Nggela (Florida) under the names vigona and tindalo. The surviving scholarly notice of Warihu is slight, and the being is chiefly of interest as one of the individually named members of a spirit-world that is otherwise described in terms of classes of beings, of the ghosts of the powerful dead, and of the impersonal power called mana that this region first gave to the vocabulary of anthropology. Sources give little of his acts, and he is best understood as a local seat of that mana rather than a figure of developed narrative.
