faces for the scaphoid and calcaneum are separated. The inner 

 cuneiform is much larger than the middle cuneiform, and has 

 projecting from its inferior bord.er a pro- 

 tuberance, with a rounded, smooth articular 

 end; its distal end projects, so as to include 

 between it and the metacarpal the proximal \q 'JjI 



end of the second metatarsal.

Metatarsals. 



The median metatarsals resemble the 

 metacarpals in the greater contraction of 

 the middle portion of the conjoined bones, 

 the ends showing a greater transverse expan- 

 sion than in Dicotyles. They are coossified 

 fully as well as in that genus. The distal 

 ends of the two bones are in the sanie 

 plane, whereas in Dicotyles the third is very 

 distinctly shorter than the fourth. The 

 second metatarsal is represented by a short 

 splint which reaches a fourth or a third of 

 the length of the conjoined metatarsals. 

 The fifth is seen in a small nodule of bone 

 articulating with the upper end of the fourth.
