referred to the Anoplotheridae (Adapts and Aphelotherium 

 from the Upper Eocene of Paris) were also Lemurs. Some 

 remains from the Lower Eocene of Suffolk were at first supposed 

 to be allied to Macacas, but were subsequently referred to the 

 Ungulate, Hyracothcrium. There is still, however, some doubt 

 as to its true affinities. 



Chiroptera. — In the Upper Eocene of Paris remains of bats 

 have been found, so closely resembling living forms as to be 

 referred to the genus Vesyertilio. 



Carnivora. — The only feline remains, are those of Hycenodon 

 in the Upper Eocene of Hampshire, and Pterodon, an allied form 

 from beds of the same age in France ; with yElurogale, found 

 in the South of France in deposits of phosphate of lime of 

 uncertain age, but probably belonging to this period. Viverridae 

 (civets) are represented by two genera, Tylodon, the size of a 

 glutton from the Upper Eocene, and Palceonyctis, allied to 

 Viverra, from the Middle Eocene of France. The Canidse 

 (wolves and foxes) appear to have been the most ancient of 

 the existing types of Carnivora, five genera being represented 

 by Eocene remains. Of these, Galethylax and Cyotherium were 

 small, and with the existing genus Canis are found in the Upper 

 Eocene of France. Arctocyon, about the size of a wolf, is 

 a very ancient and generalised form of carnivore which can 

 not be placed in any existing family. It is found in the Lowei 

 Eocene of France, and is thus the oldest known member of 

 the Carnivora. 



Ungidata. — These are more numerous. Equidae (horses) are 

 represented by the Miocene Anchithcrium in the Lower, and by a 

 more ancient form, Anchilophus, in the Middle Eocene of France. 

 Tapiridse and Paheotheridae were very numerous. Palceotherium 

 and the allied genus Pcdoplotherium, were abundant in France and 

 England in Upper Eocene times. They somewhat resembled 

 the tapir, with affinities for the horse and rhinoceros. A new 

 genus, Cadurcotherium, allied to the rhinoceros and equally 

 large, has been found in the same deposits of phosphate of lime 

 as the lemur and JElurogale. In the Middle Eocene of both 

 England and France are found Lophiodon allied to the tapir,
