Creation Myths of Primitive America, by Jeremiah Curtin, , at sacred-texts.com
Paiowa is the evening star. Wakara's most interesting daughters are always Halaia, or Halai Auna, and Paiowa. The first is the morning, the second the evening star.
Halaia's sister, Pahnino, in this myth became afterward a shell, or rather a creature which lives in a shell, as did also her mother. I do not know which kind of shell Pahnino is; it has bright colors.
The increase and decrease of food, the magic power of weapons, the jealousy and hostility of the husbands of other sisters, are usual in Yana myths of this kind.
