There is no supra-trochlear foramen, but there is an entepicondylar foramen on the inner side. The radius and ulna are like those of the dog but proportionately longer. The carpal bones and manus are very similar, but the terminal phalanges of the digits can be withdrawn, with their sharp claws, over the penultimate phalanx. Fig- 317-—A Side View of a Cat's Toe with Retractile On left the claw is retracted by the ligament behind it, on the right the tendon is retracted and the claw exserted. (After T. J. Parker.) In the hind-limb and girdle, we may note again the greater length of limb, but a general similarity to the dog. There are the same retractile claws as in the fore-limb. As in the dog, the hallux is represented by a vestigial meta- tarsal. The stomach of these carnivorous types is always simple and there is a small caecum. In the cat, the tongue is armed.
