The areas covered by the different class and phratry names are not co-extensive, that is to say a class is associated with more than one phratry and vice versa. The Undekerebina and Yelyuyendi have phratries (No. 29) which are usually associated with classes but in their case none have been noted. On the other hand it is not uncommon to find classes without the corresponding phratry names; this is the case in the eight class area, among the tribes of N.S. Wales, S. Queensland, etc.; but no special significance attaches to it unless we are certain that it is not the negligence of the observer nor the disuse of the names which has produced this state of things. On the other hand the relation of phratry and class areas is of the highest importance, as is shown in Chapter V. The following table shows the anomalies:
