Twins
Twins are called ömumokh and it is the custom to kill one of them, even when both are boys. If they should be girls, it is probable that both would be killed, or, at any rate, would have been killed in the past.
There is one case of twins in the genealogies. Iraveli, the wife of Kwötuli and Nudriki (8), gave birth to twins about twelve years ago. Both were boys, and I was first told that one had died shortly after birth, but later inquiries made it almost certain that the boy had been killed. Some time after the birth of the twins, one of the buffaloes of Kwötuli and Nudriki is said to have had a calf with one body, two heads, and four legs. The buffalo died before the calf was born, and the monstrosity was found by the Kotas, to whom the body was given. It was generally expected that something would happen to Kwötuli or Nudriki, but they have since been very prosperous.
