verse diameter and are separated by a rather shallow groove, the external condyle 
being quite oblique to the long axis of the bone. 
The fibula is heavy and has the proximal and distal ends much expanded. 
The shaft sweeps gently towards the shaft of the tibia and is also gently arched in 
the backward direction. The facet for the astragalus is nearly plane and the pos- 
terior face has the tendinal groove and external malleolus fully as well developed 
as in the recent badger or otter.

Both astragaliare represented. In comparison with the length of the bone the 
trochlea is somewhat narrower than that of Megalictis ferox. The trochlea is very 
shallow and is more oblique and imperfect than in either Meles or Lutra and rather 
more like that of Gulo luscus, the internal 
condyle being less developed, while the exter- 
nal is higher than in the two recent forms 
first mentioned. The tibial face of the inter- 
nal condyle is not interrupted by the sulcus,
