A ritual conducted by the Wanasi hunters, especially before a deer hunt?

From the text:

Elder Uncle and Timawi and Ishi sang with Grandfather the songs learned in the watgurwa, and then they danced. They danced the Dance of the Hunt, and Ishi and Timawi danced the dance of the Wanasi. Then Grandmother and Mother and Tushi danced the Around-the-fire Dance of the women, dancing to the click of deer knuckle-bones which they held in their hands.
