as in Plecotus s. str. (See Plate II, Figs 2, 4, 6, 10). The measurements of the mandibular body and ascending ramus are with considerable overlap in the three compared species, except the height of mandibular body under M/l. In this character P. townsendii is smaller than either P. atavus or P. crassidens. The coronoid and angular processes offer detectable differences. The coronoid process of the Miocene species if higher and pointing less forward than that of the Pleistocene animal. Its posterior descending margin is more oblique and the distance between its anterior margin and the incision between the articular and angular processes is relatively shorter than in P. crassidens (see Plate II, Figs 2, 4). The buccal basal portion of the angular process is concave and without a ridge, not as in P. cras sidens (see above and Plate II, Figs 1, 3, 5). The angular process itself is strongly bent outwards, like in P. townsendii. Table 2.
