with so short a calcaneum, while the metatarsals oi fossigcr, which mark the 

 extreme of shortness in the group, are joined with a comparatively long cal- 

 caneum. The inner facet for the astragalus is deeper than wide, and its long 

 axis forms an angle of 40° to 45° with the outer face of the calcaneum. In 

 fossiger the inner astragaline facet is longer than deep, and its long axis forms 

 an angle of about 90° with a line drawn vertically to the outer face of the cal- 

 caneum. The cuboid facet looks almost directly downward, while in fossiger 

 it looks sharply inward.
