夔牛: Kui Niu
It appears that Kui Niu and most of the other divine animals or demonic beasts that follows in later chapters are drawn mainly from the 山海经, (Shan Hai Jing), Classics of Mountains and Seas. See: http://en.wikipedia.org/wiki/Classic...tains_and_Seas
Images of the beasts can be found here, including the Kui Niu.
