THE PROBOSCIDIA. 
"THE Proboscidia are Ungulata in which the second row ot 
^ carpal bones has not moved inwards so as to alternate 
with the first, and in which the second row of tarsal bones 
alternates with the first by the navicular extending over part 
of the proximal face of the cuboid. The teeth are modifica- 
tions of the quadritubercular type, and canines are absent.
