SOME EARLY MAMMALS 263 
bones are still missing, enough is known to justify a tentative re- 
storation such as is shown in our Plate XLIII. See the specimens 
in the Fossil Mammal Gallery, Natural History Museum. Dr. C. 
W. Andrews proposes a new order, viz. the Barypoda (or heavy- 
footed beasts), to distinguish this creature from such of its allies 
as the Dinoceras and the Elephants. The affinities of Arsinoé- 
therium are at present unsettled, but it may possibly be related 
to the order of ungulates known as Hyracoidea, and at the present 
day represented by the Syrian Hyrax or coney. It is an isolated 
and a primitive group, probably related to the Phenacodus, as 
well as to the order Amblypoda. Queen Arsinoé, a Greek Queen 
of Egypt, had her palace near where the bones were found ; hence 
the name. The horn-cores in the skull are formed by a hollow 
shell of bone. The height of the creature was 5 feet 9 inches at 
the withers, and the length about 9 feet 9 inches from the snout 
to the rump.
