Sesamoids. —'The sesamoids are proportionally somewhat smaller than in the 
recent canids, but have otherwise no noteworthy features differing from, the latter. 
Fia. 55. Phalanges of Digits III, IV, and V, of Right Hind Foot of D. superbus. Nat. size. 1, dorsal and tibial 
views of first phalanx of third digit ; 2, fibular and plantar views of terminal phalanx of third digit ; 3, dorsal view of 
first phalanx of fourth digit; 4, tibial and dorsal views of second phalanx of fourth digit; 5, fibular and dorsal views 
of first phalanx of fifth digit. 
Note: The hood of the ungual phalanx is partly broken off. 
Phalanges. —The proximal row of phalanges are distinctly shorter in propor- 
tion to those in Daphenus, which is also true of the phalanges of the manus. They 
are otherwise quite similar in structure, the proximal articulation being a concave 
pit with a broad plantar groove, and the distal trochlea confined principally to the 
plantar face. The median row of phalanges is asymmetrical in the same proportion 
as those in the manus, and indicate that the unguals were drawn toward the fibular 
borders when the little retractility which they undoubtedly possessed, was exer- 
cised. The unguals are similar to those in the manus.
