ANTHROPOPITHECUS. 2I7 



projects obliquely forward, and is longer and narrower than in 

 Man. The late appearance of the last molar in the upper jaw 

 was supposed to be a character which was alone common to 

 Dryopithecus and Man; but Dr. Forsyth Major has observed 

 that in Macacus the same late in-coming of the "wisdom tooth" 

 occurs. The type species, Dryopithecus fontani, Lartet, 

 which lived in the Mid-Miocene forests of St. Gaudens, though 

 the most Man-like of all the Tertiary Apes, was nevertheless 

 fu!ther distant from Man than the Chimpanzees {Ant/wo- 

 popithecus). The form of the symphysis of its lower jaw in- 

 dicates that its snout was considerably lengthened. Certain 

 molar teeth found in the Bohnerz strata from Melchingen 

 and Salmendingen, in Wiirtemberg, and at one time considered 

 to be human, have now been ascribed to D. fontani, 



GENUS SIMIA {suprh, p. 170). 



To this genus has been referred a molar tooth found in the 

 Pliocene Strata of the Sivalik hills in India. It is considered 

 to belong to an Orang-Utan, Simia satyrus. 



GENUS ANTHROPOPITHECUS {suprh, p. 188). 



A fragmentary jaw, also from the Pliocene beds in the Sivalik 

 hills, has been described as Anthropopithecus sivalensis 

 by Lydekker, who at first placed it in a new genus, Palceopithe- 

 cus, but has more recently determined it to belong really to this 

 now exclusively African genus. The relative smallness of the 

 premolars distinguish it from the Orang. Should this determi- 

 nation be confirmed, the presence of a true Chimpanzee in 

 Asia will be a fact of the highest interest in the geographical 

 distribution of the SimiidcB.
