It is noted [48] that, among the Sivaganga Kallans, "when a member of a certain kilai dies, a piece of new cloth should be given to the other male member of the same kilai by the heir of the deceased. The cloth thus obtained should be given to the sister of the person obtaining it. If her brother fails to do so, her husband will consider himself degraded, and consequently will divorce her." Round about Pudukkottai and Tanjore, the Visangu-nadu Kallans have exogamous septs called pattaperu, and they adopt the sept name as a title, e.g., Muthu Udaiyan, Karuppa Tondaman, etc. It is noted, in the Gazetteer of the Tanjore district, that the sub-divisions of the Kallans are split into groups, e.g., Onaiyan (wolfish), Singattan (lion-like), etc. It is a curious fact that the Puramalai-nadu Kallans practice the rite of circumcision. The origin of this custom is uncertain, but it has been suggested [49] that it is a survival of a forcible conversion to Muhammadanism of a section of the Kurumbas who fled northwards on the downfall of their kingdom. At the time appointed for the initiatory ceremony, the Kallan youth is carried on the shoulders of his maternal uncle to a grove or plain outside the village, where betel is distributed among those who have assembled, and the operation is performed by a barber-surgeon. En route to the selected site, and throughout the ceremony, the conch shell (musical instrument) is blown. The youth is presented with new cloths. It is noted, in the Gazetteer of the Madura district, that "every Kallan boy has a right to claim the hand of his paternal aunt's daughter in marriage. This aunt bears the expenses connected with his circumcision. Similarly, the maternal uncle pays the costs of the rites which are observed when a girl attains maturity, for he has a claim on the girl as a bride for his son. The two ceremonies are performed at one time for large batches of boys and girls. On an auspicious day, the young people are all feasted, and dressed in their best, and repair to a river or tank (pond). The mothers of the girls make lamps of plantain leaves, and float them on the water, and the boys are operated on by the local barber." It is stated, in the Census Report, 1901, that the Sirukudi Kallans use a tali, on which the Muhammadan badge of a crescent and star is engraved.
