Represented by the anterior part of a skull without lower jaw. Den- 

 tition: I.?; C. 1; Vm. 2; M. 3. Posterior molar narrow; its posterior 

 external V rudiniental ; first and second molars subequal. Fourth premo- 

 lar elevated and acute, with an external basal cingulum; second premolar 

 simple, acute. Profile steeply elevated behind orbital region, less steep in 

 front of it; zygomas wide.

TAXEOPODA. 



Cope, American Naturalist, 1882, p. 523, June (May 30). 



Ungulate ; carpus with the bones of the second row directly succeeding 

 those of the first. The lunar bone is supported by the magnum, and little or 

 not at all by the unciform, and the scaphoid is supported by the trapezoides 

 and not by the magnum. In the same way the bones of the second series of 

 the tarsus do not alternate with those of the first series. The astragalus ar- 

 ticulates exclusively with the navicular, and the calcaneum with the cuboid. 



Tliis comprehensive division is, so far as present knowledge extends, 

 well distinguished from the best known orders of ungulates, the Amhhjpoda, 

 the Perissodactyla, and the Artiodactyla. 



The ungulata are here understood to be the hoofed placental mammalia 

 with enamel-covered teeth, as distinguished from the ungulate or clawed, and 

 the mutilate or flipper limbed, and the edentate or enamelless groups. The 

 exact circumscription and definition has not been attempted, though probably 

 the brain furnishes an additional basis of it in the absence of the crucial and 

 presence of other fissures, etc. Suffice it to say that it is on the whole a rather 

 homogeneous body of mammalia, especially distinguished as to its economy 

 by tlic absence of forms accustomed to an insectivorous and carnivorous diet, 

 and embracing the great majority of the herbivorous types of the world.
