t-class system and among the nominally four-class southern
Arunta the intermarriage and descent is as follows, according to Spencer
and Gillen;

_A1_ _B1_
------ = _A4_, ------ = _B3_,
_B1_ _A1_

_A_2 _B2_
------ = _A3_, ------ = _B4_,
_B2_ _A2_

_A3_ _B3_
------ = _A2_, ------ = _B1_,
_B3_ _A3_

_A4_ _B4_
------ = _B4_, ------ = _B2_.
_B4_ _A4_

In each case the male is the numerator, the woman the denominator, and
the = shows the child.

Tribes with conterminous territories usually know what phratries and
classes are equivalent in their systems. In the tables which follow the
phratries and the classes of matrilineal tribes are arranged to show
this correspondence so far as it is known. A * shows that no information
on the point is to hand. A rearrangement of patrilineal classes is
necessary to make them equivalent to the organisations of matrilineal
tribes; this cannot be shown in the tables; but full details will be
found in the works of Spencer and Gillen. A [+] indicates patrilineal
descent.

Where the names of phratries and classes are translated, the meanings
are shown in the tables; where the authorities do not give the
translation but a word of the same form is in use in the tribe or group
of tribes the meanings are given in round brackets; words in use in
neighbouring tribes are put in square brackets.
