border is coiicavely emarginate, with a small tuberosity. Its convex face is 
smooth, with a slight interruption, and is undivided. Another bone resem¬ 
bling that which I described as cuneiform in Synopolotlierium lanius is 
deficient in one end. One side presents a concave facet, the other two 
parallel concave facets separated by a ridge. The precise reference and 
relation of these two bones are rendered somewhat obscure by their incom¬ 
pleteness. Portions of three metapodial bones are relatively of small size, 
and have the proximal articular faces slightly concave in an antero-posterior 
direction. The shafts are cylindric, and the distal articular condyle slightly 
oblique, with strong lateral ligamentous fossae, and small inferior keel. A 
proximal phalange is of appropriate size: it is everywhere flat, and is 
widened at the proximal end by lateral tuberosities. The distal end is con¬ 
tracted, and the articular face angularly concave below. The tendinous 
insertions are a pair of longitudinal tuberosities. The patellm, as well as 
the bones of the feet, are small in proportion to the size of the teeth, 
indicating small limbs and feet. The patella is stout, and has the inner face 
moderately convex in transverse section.
