. Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. FELIS 461 smaller than corresponding upper teeth, their crowns rounded and flattened, with faintly indicated longitudinal groove. Canines simple, without cingulum, rather large, the shaft curved very slightly backward, that of upper tooth terete with a few longitudinal grooves in enamel, that of lower slightly hollowed on inner and posterior surface. Anterior upper premolar about as large as outer incisor, though with crown not so high, its root single, but often showing indications of longitudinal division. Its usual position is a little behind middle of wide diastema between canine and first large premolar. Other premolars (except carnassial) essentially alike in form, two-rooted, the crowns compressed, triangular when viewed from the side, some- what longer than high, the base elliptical, slightly wider posteriorly than anteriorly, that of pm^ wider than the others and somewhat inclined to assume a concavo-convex outline ; anterior border of pm^ simple, that of pm^ and pm^ with a small basal cusp (better developed in latter than in former) ; posterior borders of all three teeth with two secondary cusps, the basal formed by the rudimentary cingulum, the second on base of main cusp ; pm^ slightly smaller than the others. Upper carnassial about twice as long as broad, the outline of its crown almost an isosceles triangle, though inner side is slightly longer fig. 97. than outer; inner lobe at anterior Felia nlvestru.
