The sub-divisions of the Kallans, which were returned in greatest numbers at the census, 1891, were Isanganadu (or Visangu-nadu), Kungiliyan, Menadu, Nattu, Piramalainadu, and Sirukudi. In the Census Report, 1901, it is recorded that "in Madura the Kallans are divided into ten main endogamous divisions [47] which are territorial in origin. These are (1) Mel-nadu, (2) Sirukudi-nadu, (3) Vellur-nadu, (4) Malla-kottai nadu, (5) Pakaneri, (6) Kandramanikkam or Kunnan-kottai nadu, (7) Kandadevi, (8) Puramalai-nadu, (9) Tennilai-nadu, and (10) Palaya-nadu. The headman of the Puramalai-nadu section is said to be installed by Idaiyans (herdsmen), but what the connection between the two castes may be is not clear. The termination nadu means a country. These sections are further divided into exogamous sections called vaguppus. The Mel-nadu Kallans have three sections called terus or streets, namely, Vadakku-teru (north street), Kilakku-teru (east street), and Terku-teru (south street). The Sirukudi Kallans have vaguppus named after the gods specially worshipped by each, such as Andi, Mandai, Aiyanar, and Viramangali. Among the Vellur-nadu Kallans the names of these sections seem merely fanciful. Some of them are Vengai puli (cruel-handed tiger), Vekkali puli (cruel-legged tiger), Sami puli (holy tiger), Sem puli (red tiger), Sammatti makkal (hammer men), Tiruman (holy deer), and Sayumpadai tangi (supporter of the vanquished army). A section of the Tanjore Kallans names its sections from sundry high-sounding titles meaning King of the Pallavas, King of Tanjore, conqueror of the south, mighty ruler, and so on."
