286 ANTHKOPOID APES. 



therefore, Mesojntheeus as an interesting form of 

 apes, and this is expressed by its scientific name.* 



The separation of these two species of apes {Sem- 

 nojnthecus and Macacus) must, he considers, have 

 occurred rather late. Pliojoithecus, from the fresh- 

 water marl, Sansan, is assigned by Gaudry and 

 others to the gibbon. Lartet and Quenstedt believe, 

 however, that it is nearer to the next neighbour on 

 the south, the magot (Inuus), on account of the five 

 fangs of its last tooth. KoUner thinks the connec- 

 tion with Semnopithecus not improbable. 



Bri/ojnthecus Fontanii, of which I have already 

 spoken, seems, as I judge from a cast taken by Fric 

 in Prague, to be of an expressly anthropoid cha- 

 racter; but the scantiness of the materials do not 

 allow us to form any precise conclusions as to the 

 zoological position of this extinct animal. The 

 structure of the back teeth, as we have already 

 said, is certainly anthropoidal. Quenstedt, always 

 cautious in his judgments, is of opinion that the 

 ape's teeth found in the ironstone of the Suabian 

 Alps in the secondary mammal formation, are of 

 a decidedly anthropoid character, and the animals 

 to which they belonged must therefore have been 

 of the same type. Fossil remains of the African 

 stumpy ape (Colohus) have also been found at Stein- 

 heim. f Macacus priscus of the valley of the Arno 

 seems to be allied with the African macaca4 Owen's
