The motor field, therefore, though absolutely larger, forms a smaller fraction of the whole cortex of the brain than in the lower forms. The statement that in the anthropoid (orang-outan) brain the groups of foci in the motor fields of the cortex are themselves separated one from another by surrounding inexcitable cortex, has been made and was one of great interest, but has not been confirmed by subsequent observat'on.
But in the anthropoid Anus cg va.gina.

The motor field of the cortex is, taken altogether, relatively to the size of the lower parts of the brain, larger in the anthropoid than in the inferior monkey brains.
The Asiatic elephant; the seladang, a bison of a larger type than the Indian gaur; two varieties of rhinoceros; the honey bear (bruang), the tapir, the sambhur (rusa); the speckled deer (kijang), three varieties of mouse-deer (napoh, plandok and kanchil); the gibbon (ungka or wawa'), the siamang, another species of anthropoid ape, the brok or coco-nut monkey, so called because it is trained by the Malays to gather the nuts from the coco-nut trees, the lotong, kra, and at least twenty other kinds of monkey; the binturong (arctictis binturong), the lemur; the Asiatic tiger, the black panther, the leopard, the large wild cat (harimau akar), several varieties of jungle cat; the wild boar, the wild dog; the flying squirrel,.
The anthropoid apes are arboreal and confined to the Old World.
Together with man and the baboons, the anthropoid apes form the group known to science as Catarhini, those, that is, possessing a narrow nasal septum, and are thus easily distinguishable from the flat-nosed monkeys or Platyrhini.
The acknowledgment of man's structural similarity with the anthropomorphous species nearest approaching him, viz.: the higher or anthropoid apes, had long before Prichard's day been made by Linnaeus, who in his Systema Naturae (1735) grouped them together as the highest order of Mammalia, to which he gave the name of Primates.
