Eab. South America (Uruguay, and (?) Argentine Republic). 40661. The extremity of the terminal tube of the caudal sheath; (Fig.) from the Pleistocene of Uruguay. This specimen, although of considerable larger size, apparently agrees very closely with the terminal tube figured by Burmeister, under the name of Glyptodon clavipes, in the ' An. Mus. Buenos Aires,' vol. ii. pi. xl. figs. 7, 8, showing the irregular arrangement of the disks on the ventral surface (fig. 7), and the large subcircular lateral ones (fig. 8), which decrease regularly in size from the hindmost one. In the terminal tube of a caudal sheath referred by Owen ^ to G. clavipes, but which, as already mentioned, probably belongs to Hoplopliorus, the lateral disks are oval, and the two last are much larger than the others, while on the ventral and dorsal aspects the disks are less numerous and of a decidedly oval form. The upper surface of the present specimen is represented in the accompanying woodcut (fig. 24), where the form of the disks is well shown. Its trans- verse diameter is 0,144, against 0,075 in the corresponding element of U. ornatus (supra, p. 129). Presented by W. G, Lettsom, Esq., 1867. Fiff.
