MAMMALIA OF THE OLD WORLD.

referred to the Anoplotheridpe (Adapis 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 Macctcits, but were subsequently referred to the 
Ungulate, Hyracotherium. 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 Vespertilio. 
Carnivora. — The only feline remains, are those of Hycenodon 
in the Upper Eocene of Hampshire, and Ptcrodon , an allied form 
from beds of the same age in France ; with JElurogaU , found 
in the South of France in deposits of phosphate of lime of 
uncertain age, but probably belonging to this period. Yiverridm 
(civets) are represented by two genera, Tylodon, the size of a 
glutton from the Upper Eocene, and Palceonydis, allied to 
Viverra , from the Middle Eocene of France. The Canidae 
(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. Ardocyon, 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 Lower 
Eocene of France, and is thus the oldest known member of 
the Carnivora. 
Ungulata. — These are more numerous. Equidse (horses) are 
represented by the Miocene Anchitherium in the Lower, and by a 
more ancient form, Anchilophus, in the Middle Eocene of France. 
Tapiridm and Palmotheridm were very numerous. Palccotherium 
and the allied genus Paloplotlurium , 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,
