This it remarkable for the thortncM and breadth of the metatarsus, and for the minor 

 degree of coalescence of the three constituent bones than in other birds, the interval* between

 are arranged according to the usual numerical law in birds, three in the inner toe, four in 

 the middle, and fire in the outer toe.
