group consists of three kulams, Taccholi to which the remaining three stanis belong, Kotholi, and Kuruvattancheri. All affix Nayar to their names, and observe fifteen days' pollution. The fourth group consists of three kulams, Peruvanian Nambiyars, Chelladan Nayars, and Vennapalan Nayars. All three observe fifteen days' pollution. The name Peruvanian means great or principal oil-man; and it is the duty of this caste to present the Kurumbranad Raja with oil on the occasion of his formal installation. The fifth group consists of the three kulams, Mannangazhi, Paramchela, and Pallikara Nayars, all observing fifteen days' pollution. A member of the first-named class has to place an amanapalaga (the traditional seat of Nambudiris and other high castes) for the Kurumbranad Raja to sit on at the time of his installation, while a member of the second has to present him with a cloth on the same occasion. The sixth group consists of four kiriyams named Patam, Tulu, Manan, and Ottu respectively, and has the collective name of Ravari. The seventh group consists of six kulams, Kandon, Kannankodan, Kotta, Karumba, Kundakollavan, and Panakadan Nayars. All observe fifteen days' pollution, and the women of these six kulams have certain duties to perform in connection with the purification of women of the Vengalat, Pattillat, and Orakatteri kulams. Besides these seven groups, there are a few other classes without internal sub-divisions. One such class is known as Pappini Nayar. A woman of this class takes the part of the Brahmini woman (Nambissan) at the tali-kettu kalyanam of girls belonging to the kulams included in the third group. Another class called Palattavan takes the place of the Attikurissi Nayar at the funeral ceremonies of the same three kulams."
