50. Family Monttobes. Species Varanus — ? This species is based 



on a vertebra indicating an animal of the same size as the large 

 Monitor now hving in Africa and Asia. 



Along with these remains M. Gaudry met with one isolated spe- 

 cimen of Helix. 



The whole of the animals enumerated belong to 35 genera, of 

 which 20 are extinct, and to 51 species, of which all are also extinct. 

 To the list of Mammals the author also adds Chalicotherium, of the 

 size of a Ehinoceros, and the genus Oraskis proposed by Dr. "Wagner. 



This remarkable assemblage of animals, all of which are utterly 

 extinct, points out the geological age of the Brick- earth of Pikermi 

 to have been Upper Miocene or Early Pliocene. The fauna is for the 

 most part African in type, and proves that Greece was most intimately 

 connected with the mainland of Africa during Miocene times. In 

 the deposit of parallel age at Baltavar and Eppelsheim, no African 

 types have been found, — a fact which may be accounted for on the 

 hypothesis that those formations contain the remains of a more 

 northern group of Mammals, whence the inference may be drawn 

 that Europe in u^Iiocene times was divided into zones of life, as in the 

 Pleistocene and recent periods. The development of Mammals in 

 Europe in point of size reached a maximum in the animals of Pikermi ;
