| 英文摘要 | Lagomorph specimens collected in 1925 by the Central Asiatic Expedition from the late middle Eocene Shara Murun Formation at Ula Usu, Shara Murun Region of Inner Mongolia, are described. These specimens belong to Gobiolagus tolmachovi and a new species, G. burkei. Gobiolagus burkei sp. nov. is similar to other species of the genus in having the pear-shaped p4 trigonid, short talonid on p4 and m1, talonid transverse and shorter than trigonid except for m2, enamel ridge connecting the trigonid and talonid at the lingual side, p4 significantly smaller than m1, and m2 the largest cheek teeth. It differs from other species in being smaller and having lower crowned cheek teeth, incisor ventral to cheek teeth so that a lingual protuberance is absent, and incisor extending posteriorly below the talonid of m2. It further differs from G. tolmachovi and G. andrewsi in having a less reduced p4 talonid. Eocene lagomorph genera and species are briefly reviewed. Diagnoses are emended or provided for G. tolmachovi, G. andrewsi, G. lii, Lushilagus, Shamolagus, Hypsimylus, Strenulagus, and Dituberolagus. Two Eocene species of Desmatolagus, D. vetustus and D. ardynense, are also discussed. Photographs of holotype specimens housed in the American Museum of Natural History are presented.; Lagomorph specimens collected in 1925 by the Central Asiatic Expedition from the late middle Eocene Shara Murun Formation at Ula Usu, Shara Murun Region of Inner Mongolia, are described.
