THE AMBLYPODA. 
BY E. D. COPE. 
HE Amblypoda is that order of hoofed mammals in which 
the internal bones of the carpus are in linear series, the mag-

scaphoid; and in which the tarsal bones are interlocked, as in the 
later types of hoofed Mammalia; that is, the cuboid bone articu- 
lates extensively with the astragalus, as well as with the calcan- 
eum (see Figs, 1-2).

have five toes on all the feet, and a flat astragalus without k 
of groove. The unciform bone is extensively in conta wl

singularly small size, and are separated from the ge is 
and from the cerebellum by their crura. The feet
