While this phalanx, a left of the proximal pair, is characteristically 

 tylopoid and absolutely unmistakable as regards its group reference, 

 it is not specifically determinable. It agrees approximately in size 

 and proportions with the corresponding element in Camelops kan- 

 sasus Leidy, as that species is at present understood, but is flatter, 

 and in this respect more nearly resembles the phalanges seen in the 

 living genus Camelus.
