No. 1588, right lower jaw fragmeilt with P* — M2, x3. A and C, by Howard Hamman; B by Owen J. Poe. Generic diagnosis : Primitive dichobunid artiodactyl in which the teeth are more bunodont than selenodont; the hypocone is retained on M^ and/or M-, the metaconules are large but are neither hypertrophied nor markedly displaced and, when unworn, possess five posterior crests; there is neither a mesostyle nor ectoloph ribbing on M^ and/or M-, strong diastemata isolate the double-rooted Po; P3 is trenchant and lacks a metaconid; P^ is also trenchant but possesses a distinct entoconid and a metaconid which separates from the protoconid high on the crown; Mi has a strong paraconid separated from the metaconid but not as widely separated as in Antiacodon or Auxontodon, Mo has a variably separated paraconid, and Mg has a fused single lingual trigonid cusp; all the lower molars are elongate, with hypo- conulids closely similar to those of Hexacodus. 127.
