In the neighbourhood of Nellakota in the Madura district, the Yerrakollas have a group of seven septs called Revala, Gollavirappa, Kambli-nayudi, Karadi (bear), Uduma, Chila, and Gelipithi. Intermarriage between these is forbidden, as they are all considered as blood-relations, and they must marry into a group of seven other septs called Gundagala, Busala, Manni, Sukka, Alivirappa, Sikka, and Madha. The names of these septs are remembered by a system of mnemonics. In a note on the Tottiyans of the Trichinopoly district, Mr. F. R. Hemingway writes as follows. "Three endogamous sub-divisions exist in the caste, namely, the Erra (red) Gollas or Pedda Inti (big family), the Nalla (black) Gollas or Chinna Inti (small family), and the Valus, who are also called Kudukuduppai Tottiyans. The Valus are said to be a restless class of beggars and sorcerers. The red Gollas are, as a rule, fairer than the blacks (whence perhaps the names). The women of the former wear white cloths, while those of the latter do not. Again, they tie their hair in different ways, and their ornaments differ a good deal. The red women carry no emblem of marriage at all, while the black women wear the pottu. The reds allow their widows to remarry, but the blacks do not. Both sections have exogamous sections, called Kambalams--the reds fourteen, and the blacks nine. The reds are divided, for purposes of caste discipline, into nine nadus and the blacks into fourteen mandais. Each village is under a headman called the Ur-Nayakan, and each nadu or mandai under a Pattakaran. The former decide petty disputes, and the latter the more serious cases. The Pattakaran is treated with great deference. He is always saluted with clasped hands, ought never to look on a corpse, and is said to be allowed to consort with any married woman of the caste."
