CHAPTER IV.
TABLES OF CLASSES, PHRATRIES, ETC.
In order to facilitate reference and to diminish the necessity for footnotes a survey of classes and phratries is here given. It will be well to explain how they are arranged.
In the two-phratry system the rule of intermarriage is clear; a man of phratry A marries a woman of phratry B and vice versa. The direct descent of the kinship name is obviously the rule.
The four classes are arranged according to the phratries; the normal rule is that a man A1 marries B1, A2 marries B2; their children are in matrilineal tribes A2 and B2, in patrilineal B2 and A2. In the patrilineal Mara and Anula, by exception, the rule of descent is direct; it will be remembered that a dichotomy of the classes prevails, so that they really belong to the eight-class system.
