The following arrangement is proposed: — 
I. Os magnum supporting os lunare, and not articulating with os 
scaphoideum. „ . 
a. Astragalus articulating only with navicular. 
Fibula with interlocking articulation with astragalus. 
llyracoidea. 
Fibula with lateral contact only with astragalus. 
Taxeopoda (Ord. nov.) 
b. Astragalus uniting with both navicular and cuboid. 
Lunar united to unciform ; fibula only in contact 
with astragalus. Amblypoda. 
II. Os magnum supporting os scaphoideum ; lunar supported in 
part by unciform. Astragalus uniting with both cuboid and 
navicular. 
Astragalus truncate distally ; median digit longest. 
Perissodactyla . ' 
Astragalus ginglymoid distally ; two median digits equal. 
Artiodactyla. 
The new order Taxeopoda is then subdivided into the Proboscidea and 
the Condylarihra * ; and the Toxodontia should, perhaps, form a third 
* It being impossible to follow the rapid changes made by Prof. Cope in the 
arrangement of the numerous new forms described by him, the order adopted last 
year is continued for the present, the Condylarthra being still treated as a sub- 
order of the Perissodactyla (see infrd, p. 32). — 0. T.
