An accessory ossicle, x, is wedged into the outerside of the carpus in Das. gigas. In Das. Peba, fig. 260, thereare four digits on the fore-foot, the two middle much exceedingin length and strength the outer and inner ones: the pollex, I, is obsolete. The femur, figs. 260, 277, 65, presents a third tro-chanter. The proximal and distal extremities of the tibia, 68, and fibula, 67, are connate : their shafts subsequently coalescetherewith, so that a single epiphysis answers to the shafts of bothbones at each of their extremities, in the immature Armadillos.The naviculare is remarkable for its two inferior tuberosities, the interspace between which receives the under part of theentocuneiform bone. In Das. sex-cinctus it sends downward aprocess, like that in some Rodents.

The chief modification of the limb-bones in the extinctgigantic Armadillos {Glyptodon) relates to the modification ofunguiculate feet to the support and terrestrial progression ofspecies too huge for burrowing, and asheavy as the bulky Pachyderms. The 2Ja^ungual phalanges are accordingly obtuse, short, broad, and thick, for being incased inhoof-like nails, and their phalanges are flatbones, presenting the maximum of breadthin proportion to length. In the third tro-chanter and the anchylosed tibia and fibulathe Dasypodoid characteristics are pre-served. The limb-bones of the Orycteropus moreresemble those of the Armadillos than of Cm^Lfeh^^r.the toothless Anteaters. The acromion scapula? is less elongate: the entocondyloid process of the humerusis recurved, and widely perforated. The wrist-bones are as inDasypus
