_Vei-ndauveni._--Let us now consider the relations between females who
would have been concubitants had they been of opposite sexes. They are
called _vei-ndauveni_, which, according to our phraseology, would mean
cousin and sister-in-law, for in the concubitant system these terms are
one and the same thing. As in the case of the concubitants, the
_vei-ndauveni_ is curiously stretched to cover the case of a man
marrying a stranger woman unrelated to him. She becomes _vei-ndauveni_
to his sister as a logical deduction from the fiction that she is
concubitant with him, and as the children of _vei-ndauveni_ must be
concubitant, so her children and her sister-in-law's children are
concubitants.
