This species is at present unrepresented in the Museum Collection, although it is important that it should be noticed here; at present it appears to be only known by immature specimens. In mm. 4 the ridges are interrupted and the valleys partially blocked by accessory tubercles ; the hind talon of mm. 3 is so largely developed as prac- tically to form a third ridge (woodcut, fig. 9). The mandibular symphysis is produced to a considerable extent, and is furnished with incisors ; but premolars do not appear to have been developed. The ridges of the milk-molars appear to be lower than in M. pandionis. Fig. Mastodon pentelici.—The left upper milk-molars ; from the Lower Pliocene of Pikermi. |. (After Gaudry's ' Enchainements.') Hah. Greece, Hungary3, and North-west Persia4 (Lower Plio- cene). Mastodon falconeri, Lydekker 5. This species is of very large size, and apparently has a short and incisor-less mandibular symphysis; the cheek-teeth present trefoils on one column of each ridge and resemble in general structure those of M. angustidens, although they are much larger and relatively wider. The species may be a more specialized descendant from the 1 Comptes Rendus, vol. xliii. p. 273 (1856).—M. pentelicus. 2 Proc. Amer. Phil.
