pointed out that these three latitudinal facie* are not confined to 

 Hump*- luit arc traceable in other parts of the world; thus the 

 Boreal f'.iri.-s extends from Russia through Turkestan into Tibet, 

 and nvurs in North America ; the temperate type recurs iu the 

 Caucasus and the Himalaya, and again in California; while the 

 Mediterranean type is found in Asia Minor, Algeria, and Abyssinia, 

 ami a^ain in Mexico. 



Moreover, in the southern hemisphere the Jurassic deposits 

 found in South Africa, Argentina, New Zealand, and Australia 

 contain a fauna which does not resemble that of the Mediterranean 

 or Equatorial facies, but is very similar to the assemblage of genera 

 occurring in the corresponding beds of England and Germany. 

 The facts, therefore, so far as they are known, certainly tend to 

 con firm Xeumayr's view.
