DISTRIBUTION OF EXTINCT ANIMALS.

tinued to exist till the Older Pliocene period. There are three 
large species of Rhinoceros, as well as a species of the extinct 
genns Leptodon of smaller size. Eemains of a very large wild 
boar ( Bus ) were found. Very interesting is the occurrence of a 
species of giraffe (Camelopardalis) as tall as the African species 
but more slender ; and also an extinct genus Helladotherium, not 
quite so tall as the giraffe but much more robust, and showing 
some approach to the Antilopidae in its dentition. Antelopes 
were abundant, ranging from the size of the gazelle to that of 
the largest living species. Three or four seem referable to living 
genera, but the majority are of extinct types, and are classed 
in the genera Palceotragus, Palceoryx, Tragocerus, and Palceoreas ; 
while Dr cm o the rium is an ancient generalized form of Cervidce 
or deer. 
Proboscidea. — These are represented by two species of Masto - 
don, and two of Dinotherium, an extraordinary extinct form 
supposed to be, to some extent, intermediate between the 
elephants and the aquatic manatees (Sirenia.) 
Rodentia — This order is represented by a species of Hystrix, 
larger than living porcupines. 
Edentata . — This order, now almost confined to South America, 
was represented in the Miocene period by several European 
species. Ancylotherium and Macroiherium, belonging to an extinct 
family but remotely allied to the African ant-bear ( Orycteropus ), 
occur in Greece. 
Birds. — Species of Phasianus and Callus were found ; the 
latter especially interesting as being now confined to India. 
Reptiles, — These are few and unimportant, consisting of a 
tortoise ( Testudo ) and a large lizard allied to Varanus. 
Summary of the Miocene Fauna of Greece. — Although we can- 
not consider that the preceding enumeration gives us by any 
means a complete view of the actual inhabitants of this part 
of Europe during the later portion of the Miocene period, we 
yet obtain some important information. The resemblance that 
appeared in the Pliocene fauna of Europe, to that of the open 
country of tropical Africa, is now still more remarkable. We
