The Cuboid. 



(Plate XLIX, figure.s 1-6, Plate LIV, figure 2, ch; and 



woodcuts 145-140, below.) 



The cuboid in the Dinocerafa corresponds in general with that- of the 



elephant, and presents similar articular faces, though not to the same 



bones. It is also more elongated in the line of the axis of the foot, thus 



appearing less flattened than in the Prohoscirlea. In genei'al shape, the 



bone is triangular, the longest side being nearly straight, and lying along 



the inner, or side for the navicular, while the shortest side is somewhat 



curved, and is presented to the exterior, or dorsal, surface of the foot.
