order, which he divides into thre6 sub-orders ; — I. Insectivora vbra ; 
II. Oreodonta (sub-ord. nov.), with the American genera Ambloctonus, 
Sfypolophus, Oxycena, Didymictis, and perhaps Diacodon [infr^, p. 12], 
and the French Pterodon and Palceonictis ; III. .Tillodonta. Their 
analogies with the Marsupials are pointed out. Mesonyx is regarded 
as a true Carnivore, and made the type of a new Family, Mesonychidce.

^ TILLODONTIA.^^ 
Under this name, O. C. Marsh characterizes a new order, combining 
the characteristics of Carnivores, Ungulates, and Rodents. Dentition, 
i. Y, c. T, p. I, ni. Y- The incisors resembled those of Rodents, the arti- 
culation of the mandibles that of Ungulates, while the rest of the 
skeleton was most like the Carnivores, the feet being plantigrade 
with compressed and pointed ungual phalanges, but the scaphoid 
and lunar were distinct, and the femur had a third trochanter. The 
type is Tillotherium [cf. Zool. Rec. x. p. 15], from the Eocene of 
Wyoming, and other genera vrill probably form two families, Tillo- 
theridcBy with rooted molars, and StyUnodontidce, with rootless molars ;
