The other species distinguished by M. Du Chaillu[176] is the _Kooloo-Kamba_. He is distinguished from all his congeners by a very peculiar cry. While offering a general resemblance to man, he approaches him more nearly in certain respects than all the other known apes. His head is very remarkable, and presents a curious analogy to that of an Esquimaux or a Chinese. His face is hairless, and wholly black. The forehead is loftier than that of any of his congeners, and the capacity of his skull is also greater in proportion to his height. A wider space occurs between his eyes than is customary with the great Simiadæ. He has a flattened nose, high projecting cheek-bones, hollow cheeks, and a well-marked orbitary arch. The muzzle is less prominent, and larger in proportion than that of other apes. Both sides of his face are ornamented with straight tufts of hair, which, joining below the chin like whiskers, communicate a strange human character to the whole countenance. His arms descend below his knees. All the body is hairy. The shoulders are broad, the hands long and narrow, and well adapted for climbing trees. Both arm and hand are exceedingly muscular; the abdomen is very prominent. The ample ears rather resemble those of a man than the ears of any other ape. * * * * * Our peregrinations now bring us to the giant of the Quadrumana, the true king of the forests of Equatorial Africa; in a word, to the _Gorilla_, whom Buffon has described under the name of _Pongo_, almost as exactly as he pictured the Chimpanzee under that of _Jacko_. We cannot be said to have known the Gorilla for more than a quarter of a century. It was in 1847 that Dr. Savage, an American missionary, recognized the Pongo as a species of the genus Troglodytes, distinct from the Chimpanzee, and named him _Troglodytes Gorilla_, in allusion to the celebrated narrative of the Carthaginian Hanno relative to the pretended female Gorillas which that navigator professed to have seen in an island of the Gulf of Guinea. Since that period the Gorilla has been carefully studied by the eminent naturalist Professor Owen. Messieurs Gautier and Franquet, French naval surgeons, collected some important information upon the habits and physiology of this great ape, and M. Franquet procured for the Paris Museum the skeleton of an adult Gorilla. Other dead and preserved specimens have since been imported into England and France, and the anatomy of this African Troglodytes is accurately known. And, finally, M. Du Chaillu, in the work already quoted, has supplied numerous strange and interesting details, which, if at first discredited and contested, are now very generally accepted as strictly accurate. The name of "Pongo," applied to the Gorilla by Battel and Buffon, is clearly a modification or corruption of that of the tribe of Mpongwéss, who dwell on the banks of the Gaboon, not far from the forests tenanted by this mysterious Quadrumane.
