TERTEBRATA. 273 



The Fallow-deer is stated to have had a wide European range in 

 prehistoric times, and to have inhabited Lebanon and England. In 

 historic timds it has occurred in Egj'pt and Assyria. It is now found 

 wild in Asia Minor, North Africa, Sardinia, probably in Spain, in 

 Greece, the CeTcnnes, and the Alps of Dauphine. L. C. M.

 pp. 358-362, plates 24-26. 



The mandible of Leiodon is composed of four bones, viz. dentary, 

 coronoid, angular, and splenial or opercular, and is Lacertian in 

 character. The crown of the tooth has a simple conical form, and is 

 polished, striated, and of a dark colour. The fang is tapering and 

 subventricose in form. The teeth are Acrodont, and allied in this 

 character to the Mosasaurus. R. E., Jun.

 ontograpliica, Bd. xxii. 5te Lief. pp. 291-346, with 5 plates. 



The third instalment of a monograph on Anthracotherium and its 

 allies, the letterpress referring to this genus alone. The examples 

 illustrated are chiefly those from the Molasse of Rochette, near 

 Lausanne and Bumbach. Of the limbs and extremities most of the 

 bones have been found ; upper and lower jaws from Rochette are 

 drawn ; but the skull has not been found uucrushed. A restoration of 

 A. valdense is given. E. B. T.

Contains a detailed description of the long bones and the limbs. 

 Some crania and teeth are figured, but without express description. 

 The general organization of the family Hyopotamklce is discussed ; and 

 the author seeks to throw light on the derivation of the existing un- 

 gulate types. Anoploihenum has hitherto been regarded as a primitive 

 form or common ancestor of the Paridigitate (Artiodactyle) Ungulata. 

 This position has been assigned to it partly owing to its antiquity 

 among fossil Ungulates, but chiefly because it was fully described by 

 Cuvier, while no adequate account of its fossil allies was accessible. 

 The author considers Anoplotherium the last remnant of a dying-out 

 branch, not as the progenitor of the varied Paridigitata of the Miocene 

 and Pliocene epochs. The feet of this genus are so much reduced, 

 presenting only two developed digits, that it is impossible to suppose it 

 the ancestor of the whole group of Miocene, Pliocene, and recent 

 Paridigitates, many of which have four functional toes. Moreover 

 Anoplotherium J like forms on the verge of extinction, is exceedingly 

 poor in specific forms. The Hyopotamldce, on the contrary', are rich 

 in subgeneric and specific forms. The family contains both didactylo 

 and tetradactyle genera, and ranges back to the Eocene period. 

 PalaDontology does not reveal the common ancestor of both Paridigitata 

 (Artiodactyla) and Imparidigitata (Perissodactyla), which may be con- 

 jectured to have been a pentaductyle ungulate, possibly of I^. Cretaceous
