Aruva.—The Aruvas are an interesting caste of cultivators along the sea-coast in the Berhampūr tāluk of Ganjam. They say that they are descended from the offspring of alliances between Patānis (Muhammadans) and Oriya women. Like other Oriya castes, they have a number of titles, e.g., Nāyako, Pātro, Podhāno, Ponda, Mondolo, and Mollana, some of which seem to be exogamous, and there are also numerous exogamous septs or bamsams. The headman is styled Nāyako, and he is assisted by a Bhollobhaya. Both these offices are hereditary. The Aruvas say that they belong to two Vēdas, viz., the males to Atharva Vēda, and the females to Yajur Vēda. Muhammadans are believed by them to be Atharvavēdis.
