Naravidyavaru.--These are Vipravinodis, who are Jangams by caste. They style themselves Naravidyavaru when they perform acrobatic and other feats before ordinary people, and Vipravinodi when they perform before Brahmans. The name Naravidyavaru is said to be a contraction of Narulu-mechche-vidya-cheyu-varu, i.e., those who receive the approbation of men. One of their most favourite feats is throwing three or four wooden or stone balls up into the air, and rolling them quickly in succession over various parts of the body--arms, chest, etc. Nariangal (nari, jackal).--An exogamous sept of Vallamban.

Nattan.--At the Census, 1901, nearly 12,000 individuals returned themselves as Nattan, which is stated by the Census Superintendent to be "a vague term meaning people of the country, reported by some to be a main caste, and by others to be a sub-caste of Vellala. Nearly all of those who returned the name came from Salem and were cultivators, but some of them entered themselves as possessing the title of Servai, which usually denotes an Agamudaiyan" (see Servai, Servaikaran). Nattan also occurs as a title of the Tamil Sembadavan and Pattanavan fishing castes, and of the Vallambans. Portions of the Tamil country are divided into areas known as nadus, in each of which certain castes, known as Nattan or Nattar, are the predominant element. For example, the Vallambans and Kallans are called the Nattars of the Palaya Nadu in the Sivaganga zamindari of the Madura district. In dealing with the tribal affairs of the various castes inhabiting a particular nadu, the lead is taken by the Nattars. Nattati (the name of a village).--A sub-division of Shanan.
