(From Hegner, after Newman and others.) Radiating from this focus, adaptations for rapid running (cur- sorial adaptations) are chiefly evident in a lengthening of the limbs. Thus, for example, in the Dogs, Foxes, and Wolves, the effective limb length is increased by raising the wrist and heel from the ground and walking merely upon the digits (digitigrade) ; while in Antelopes, Horses, and hoofed runners in general, the.
