Castes and Tribes of Southern India/Kalkatti
Kalkatti.— Kalkatti, denoting, it has been suggested, those who wear glass beads, is a sub-division of Idaiyan. The Lingāyats among Badagas of the Nīlgiri hills are called Kalkatti, because they hang a stone (the lingam) from their necks in a casket. Some Irulas of the same hills are also said to go by the name Kalkatti.
