"The ecto- and meso-cuneiforms are completely coossified, there being no trace of the suture visible. This compound bone is broad and flat, and rests upon the second and third metapodials. The articulation with these bones is by a broad flattened surface, which is also true of the articular surface by which it supports the ; The ento-cuneiform is a long slender styliform nodule articula- ting by a double facet with the navicular and compound cunei- form ; upon its anterior internal face is seen another elongated facet by which it joins the posterior surface of the head of the second metatarsal. When in place, it lies anterior and internal to the navicular hook. In our original description we erroneously supposed that a hallux was present, but our present material shows that this bone did not support a metatarsal. The hallux was therefore absent. The general shape and connections of the bone are similar to that of Oreodon. The Metatarsus.—" Of the metatarsals, the two median ones, mts. Ill and IV, are almost if not quite equal in size and length. The lateral ones, mts. II and V, are practically so, the disparity in their length being slightly greater than that found in the pig. While the outer one (mt. V) is a little the longer of the two, the inner one (mt. 11) is the stronger. This appears also to be true of all the more generalized Artiodactyla in which four toes are present. In the rabbit, on the other hand, mt. II, is both longer and stronger than mt. V, and this is also true of the median pair, the inner one slightly ex- ceeding its fellow in size and length. " The two outer metatarsals (IV and V ) are supported wholly by the cuboid, while the two inner ones (II and III) are supported
