tibiale

from The Century Dictionary.

• noun A bone of the tarsus, the inner one or the proximal row of tarsal bones on the tibial side of the tarsus, in especial relation with the tibia, as is the astragalus, which is by some supposed to be the tibiale, while others consider that the astragalus, besides representing the tibiale, includes also the bone called intermedium. See cuts under Ichthyosauria, Plesiosaurus, and tarsus.
