TEE SKELETON OF THE LIMBS. 103 open forwards, and when the body is supported as in walking, the fore-legs are in pronation. _ ; The skeleton of the fore-leg below the elbow is divisible into a tri- and a bi-digital series, placed side by side.

Showing the elastic ligament which passes from above the root of the claw, downwards and backwards to the distal part of the second phalanx ; also the long flexor tendon (which by being pulled backwards draws down the claw) passing through the ligamentous loop attached to the under surface of the middle phalanx. The sesamoid bone beneath the distal end of the metacarpal is also shown. trapezium, the trapezoides, and the magnum ; the first, second, and third metacarpals; and the annexed digits forming the tri-digital series. We have, secondly, the ulna ; the cuneiform; the unciform ; the fourth and fifth metacarpals ; and the corresponding digits—forming the bi-digital series. THE SKELETON OF THE PELVIC LIMB. § 11. The bones of the cat's pelvic limb are divisible (like those of its pectoral limb) into three categories : A, that of the hip; B, that of the hind-leg ; and C, that of the hind-foot. A. The skeleton of the hip, or haunch bone, is called the os innominatum; and there is one such on either side in the adult animal. B. The skeleton of the leg is sub-divisible into (a) that of the thigh, which consists but of one bone, called the femur; (b) that of the lower part of the leg, which consists of two bones placed side by side. The larger of these is called the tibia ; the other, much more slender and placed on the outer side of the leg, is called the fibula. It is also called the peroneal bone of the leg, because it clasps, as it were, the larger bone. C. The skeleton of the hind-foot, like that of the fore-foot, is
