Fig. 57 (p 444) is a view of the fossil showing the outer side of the tooth and jaw, natural size 

 Fig. 58 A is the same view, magnified two diameters. 



B is a view of the fossil looking down upon the grinding surface of the tooth, similarly 

 magnified. It does not show distinctly the inner small cusp of the ' talon ' or hinder 

 tubercle. 

 C. A view of the fossil from the inner side, magnified two diameters. 



Fossil remains of Quadrumana have been discovered with- 

 in a recent period in the tertiary formations of India, of the 

 South of France, and of the Brazils. 



The Indian remains, discovered by Messrs. Baker and Du- 

 rand, and those subsequently found by Messrs. Falconer and 

 Cautley, have been referred to a species of Semnopithecus, 

 as large as the Entellus, and consequently exceeding consi- 

 derably the present fossil in size. 



The portions of fossil quadrumanous lower jaw discovered 

 by M. Lartet in the South of France, indicate a species of 

 Hylobates, rather smaller than the Syndactylies, but nearly 

 allied to that species. 



The South American extinct quadrumanes, discovered by 

 M. Lened in the basin of the Rio des Velhas, it is interesting 

 to find, are referable to a form peculiar to the New World, and 

 are most nearly allied to the genus Callithrix ; but the ex- 

 tinct species are more than double the stature of any of those 

 which exist at the present day. 



Not only therefore is the fact of the existence of quadru- 

 manous mammals at the tertiary periods of the earth's history 

 demonstrated, but we have evidence that four of the modifi- 

 cations of the quadrumanous type at present recognized were 

 in being at that remote epoch : that is to say, the tail-less ape 

 (Hylobates), the gentle, vegetable-feeding semnopithecque, 

 distinguished by its complicated stomach ; the more petu- 

 lant and omnivorous macacque, and the platyrrhine Colli- 

 thrix. Lastly, we have the interesting fact established, that
