Castes and Tribes of Southern India/Kusa
Kūsa. — A sub-division of Holeyas in South Canara, who also call themselves Uppāra. Some of them say that they are the same as Uppāras of Mysore, whose hereditary occupation was the manufacture of salt from salt-earth (ku, earth). Kūsa further occurs as a synonym of the Otattu, or tile-making section of the Nāyars, and Kūsa Mārān as a class of potters in Travancore. Kūsa is also an exogamous sept of the Bōyas.
