Andrew Lang,
The Secret of the Totem
“ Where totem and phratry names only exist, a man has merely to ask a woman, "What is your phratry name?" If it is his own, an amour is forbidden. Where phratry names are obsolete, and classes exist, he has only to ask, "What is your class name?" If it is that of either class in his own phratry of the tribe, to love is to break a sacred law. It is not necessary, as a rule, even to ask the totem name. What looks so perplexing is in essence, and in practical working, of extreme simplicity. But some tribes have deliberately modified the rules, to facilitate marriage. ”
