Yayati in his conversation with Ashtaka mentioned about two-legged, four-legged and six-legged animals.
"Yayati answered, 'After falling from heaven, the being becometh a subtile substance living in water. This water becometh the semen whence is the seed of vitality. Thence entering the mother's womb in the womanly season, it developeth into the embryo and next into visible life like the fruit from the flower. Entering trees, plants, and other vegetable substances, water, air, earth, and space, that same watery seed of life assumeth the quadrupedal or bipedal form. This is the case with all creatures that you see.' ...............
"Ashtaka asked, 'After death, the body is burnt, or otherwise destroyed. Reduced to nothing upon such dissolution, by what principle is one revived?' Yayati said, 'O lion among kings, the person that dies assumes a subtil form; and retaining consciousness of all his acts as in a dream, he enters some other form with a speed quicker than that of air itself. The virtuous attain to a superior, and the vicious to an inferior form of existence. The vicious become worms and insects. I have nothing more to say, O thou of great and pure soul! I have told thee how beings are born, after development of embryonic forms, as four-footed, six-footed creatures and others with more feet. What more wilt thou ask me?'
Although Yayati mentioned that there are beings with more than six foot. He did not tell explicitly any number more than six.
Do scriptures of Hinduism mention any other numbers restricted to legs of creatures other than two, four and six?
