Lower molars, No. 14124, natural size, internal and crown views. Cervus sp. A second form, somewhat smaller than the preceding, is represented by jaw fragments and teeth, Nos. 14126, 14127. These lack the “Paheorneryx fold” in the lower molars, the heel of m3 is narrow7 and its internal cusp less prominent, the teeth are slightly less brachydont, and the surface of their enamel less rugose. The reference to Cervus is only in a broad sense; they might with equal propriety be referred to Odocoileus, Mazama, Cervus s. s., Dama, or to Schlosser’s genus Cervavus. A very similar but smaller species occurs in the Upper Miocene of South Dakota; it has not received a name.
