commit a sin vicariously. This Ape has immense powers of leaping—a space of 20 to 30 feet can be cleared by them if one side, that from which the leap is taken, be considerably higher than the other. They are useful to the Tiger hunter, as they follow and hoot at this, their deadly enemy. S. schistaceus is a species which lives at great heights, not less than 5000 feet, in the Himalayas.
The genus Nasalis is hardly separable from the genus Semnopithecus. It is a Bornean animal, and is distinguished by a comical long nose, which not only suggests, but goes beyond, the aquiline nose of the human species. It is no doubt on this account that the Borneans, unconsciously imitating our habit of comparing "natives" in general to Monkeys, call it by a name which signifies "white man." Rhinopithecus has also a long, but a more definitely upturned nose.
Fossil Monkeys.—Several of the existing genera of Old-World Apes are also known to have existed in past times; in some cases their past distribution indicates a greater range. Thus Macacus is now represented—and that doubtfully—in Europe by the Barbary Ape alone. But from Montpellier have been unearthed the remains of M. priscus, from Pliocene beds. The Asiatic Semnopithecus is known to have lived during the Pliocene period; its remains are discovered in France and Italy, as well as in Asia. In addition to these existing forms, a number of totally extinct Old-World genera are known. The rich formation at Pikermi near Athens has produced Mesopithecus pentelici; this Monkey has a skull which recalls that of Semnopithecus, while the stout limbs are rather Macaque-like. As is the case with many living Catarrhines, the males have stronger canines. The animal had a long tail.
An analogous annectent character is shown by the Italian fossil, Oreopithecus bambolii. This animal was referred by one palaeontologist to the Man-like Apes, by another to the Cercopithecidae. It suggests a common ancestral form, and is Middle Miocene in horizon.
Just as there are no Platyrrhine Apes in the Old World so there are no Catarrhines met with in a fossil condition in the New World; the two great divisions of the Apes were as distinct in the past, so far as we know, as they are now—a strong argument in favour of those who would derive them from two sources.
