Description of new genera and species of fossil Mammalia from the

Mastodon , Dibelodon , and Tetrabelodon. 
71. -. On the Structure of the Feet in the Extinct Artiodactyla of 
North America. T. c. pp. 21-27. 
Contains a precise account of the structure of the tarsus of several 
genera of Bunodont and Selenodont Artiodactyla , among others of Panto- 
lestes. Observations on phylogeny follow, in which the whole Artiodactyle 
phylum is derived from Pantolestes. 
72. -. The Amblypoda. Am. Nat. xix. pp. 40-55, pi. i. [continued 
from p. 1202, vol. xviii.]. 
Contains an account of the Dinocerata, the last sub-order of the Ambly¬

gressive. T. c. pp. 140-148, 234-247, & 341-353. 
The Mammals are treated of, p. 346; a table of the classification used is 
given. The following are the names of the 14 orders recognized by the 
author: 1, Monotremata ; 2, Marsupialia ; 3, Cetacea ; 4, Sirenia; 5, 
Taxeopocla, containing 5 sub-orders— (a) Conchy larthra, ( b ) Hyracoidea , 
(c) Daubentonoidea, (d) Quadrumana , and ( e) Anthropoidea ; 6. Probos¬ 
cidean 7, Amblypoda ; 8, Diplarthra . including Perissodactyla and Artio¬ 
dactyla ; 9, Edentata ; 10, Rodentia ; 11, Chiroptera ; 12, Banotheria ; 
13, Carnivora. The order that explains the phylogeny of most of the 
Mammalian groups is the Condylarthra. The author then shows the pro¬ 
gressive modifications of Mammals in the several points, such as the feet 
and digits, the vertebrm, and the dentition.
