The anterior limb elements (figs. 9-12) suggest a form fully as tall 

 but slighter, and longer-shanked than the modern mule-deer. The 

 metacarpus is of very similar form to the metatarsus described above, 

 and may represent the same species. Compared with the correspond- 

 ing bones of Odocoileus hemionus: (1) the humerus (fig. 9) is slightly 

 shorter and lighter; (2) the radius (fig. 11) is slightly lighter and of 

 about equal length; and (3) the metacarpus (fig. 12) is distinctly 

 longer.

The two astragali (see reconstruction, figs. 14a-14c) are consider- 

 ably heavier and of different character from no. 23403 (see above, 

 fig. 13), being strongly cervid throughout in: (1) the groove of the 

 distal end is deep and sharply defined, and the outer condyle of the 

 trochlea broad; (2) the occurrence on either side of the central fossa 

 of a knob which terminates mid-dorsally both condyles of the jiroximal
