Conclusions 



The apparent absence of arctotheres, of true bears, and of 

 eats of the puma group from the Raneho La Brea fauna, has 

 appeared to give this assemblage a distinctly ancient aspect com- 

 pared with other Pleistocene faunas in the Pacific Coast region. 

 There are still many peculiar features in the life of Raneho La 

 Brea which make it seem quite different from that of the Pleis- 

 tocene known from other localities of this province. Some of 

 these peculiarities will be interpreted as due to difference in 

 time, and some to difference in habitat. The known presence of 

 true bears, arctotheres, and cats of the puma group brings the 

 Raneho La Brea fauna into closer relation with the other Pleis- 

 tocene faunas of this region than had previously seemed possible.
