320 HISTORY OF THE EUROPEAN FAUNA. 



Sardinia now form the remains, and also on to North- 

 west Africa. Indeed, we find high up in the Corsican 

 mountains an interesting large brownish-grey Newt 

 {Molge montana), and another in Sardinia (Molge 

 Rusconii). Again, in Algiers there are two species, 

 viz., Molge Poireti and M. Hagenmillleri, while the 

 Moroccan M. Waltlii passes into the south of Spain. 

 Here Molge boscce, M. aspera, and M. mannorata 

 originated, the latter passing into France. 



Another branch of the Molge tribe turned north- 

 ward from Greece towards the newly forming Alps; 

 and there originated Molge alpestris and M. palmata, 

 which more recently have spread into England (one at 

 least), Germany, France, Austria, and Southern Italy. 

 Molge vulgaris is an Asiatic species which wandered 

 northward after entering Europe, covering a large 

 area, but never reached the extreme south or south- 

 west. M. cristata the large Water Newt has a 

 similar but not quite so extended a range, while 

 M. vittata never managed to cross the borders of 

 Asia Minor. Some of the other species occur in 

 China, Japan, and North America. 



None of the tailless Batrachians the Frogs and 

 Toads are peculiar to the Alps, but one, viz. Rana 

 temper aria> ascends to the height of no less than 

 10,000 feet. It is our common British Frog. No 

 other Frog probably ranges so far north or to such 

 heights. 



Let us now inquire what the invertebrate fauna of 

 the Alps teaches us. We are told by Dr. Kobelt,
