After traveling to land of South the what is the name of land between the place of hammer head people and the land of South where Dorothy had injured a cow's leg too ?

The land was the country of the Quadlings.

"It shall be done," said the King, and at once the Winged Monkeys caught the four travelers and Toto up in their arms and flew away with them. As they passed over the hill the Hammer-Heads yelled with vexation, and shot their heads high in the air, but they could not reach the Winged Monkeys, which carried Dorothy and her comrades safely over the hill and set them down in the beautiful country of the Quadlings.
