rostral width at the outer alveolar border of the canines, and at the crowns (and at alveoli) of M3/-S is greater in P. crassidens than in P. townsendii. The same is true for the lacrimal width and width of the postpalate. The width of the narial notch and that of the anterior palatal emargination, as well as the depth of palatal emargination well exceed those of P. townsendii, whilst the depth of the intermaxillary notch equals the two compared species. Maxillary height at P4/ anterior root equal in the fossil and recent species, the maxillary height above M2/, however, is evidently lower in P. crassidens than that of P. townsendii. Thus almost all rostral width measurements show a decidedly wider rostrum of the fossil species (see Plate I, Figs 1, 4; Table 1).
