This specimen is noticed by the present writer in the Geol. 

 Mag. dec. iii. vol. i. p. 548 (1884). It is slightly smaller 

 than the corresponding tooth in the Ufhofen palate of 

 A. magnum (No. 28770), and would therefore agree well 

 in size with the present species, the type of which was 

 obtained from beds referred to the horizon of the Hemp- 

 stead beds. The present specimen is apparently too large 

 to have belonged to A. minus. The height of the crown (of 

 which the summit is abraded) is 0,025, the antero-posterior 

 diameter of the base of the crown 0,020, and the transverse 

 0,017. Hastings Collection. Purchased, 1855. 



29907 a. Cast of the second left upper incisor ; from the Lower 

 Miocene of Buchsweiller (Bas-Khin), Alsace. 



Egerton Collection. Purchased, 1882. 



M. 2224. A right fourth metatarsal, provisionally referred to this 

 species ; from the Upper Eocene of Caylux. This spe- 

 cimen agrees very closely with the one figured by Kowa- 

 levsky in the ' Palseontographica,' vol. xxii. pi. xi. fig. 55. 

 The corresponding bone of Elotherium (vide Pilhol, Ann. 

 Sci. Geol. vol. xii. pi. xxviii. fig. 147) differs by the absence 

 of the median ridge on the anterior aspect of the distal 

 trochlea. Purchased, 1885. 



Anthracotherium valdense, Kowalevsky l . 



Hab. Switzerland. 



M. 1949. The associated second and third right upper true molars 

 of a large Anthracotherium ; probably from the Lower-Mio- 

 cene lignites of Rochette, near Lausanne, Switzerland. If 

 the locality be correct, these specimens probably belong to 

 A. valdense. The summits of the teeth are but very slightly 

 touched by wear ; and m. 3 is remarkable for its great 

 width. The length of the latter tooth is 0,055, and its 

 greatest width 0*075. Presented by Dr. Kowalevsky. 



M. 1950. Fragment of a ramus of the mandible, with the broken 

 premolar and canine ; probably obtained from the same 

 locality as the preceding, and belonging to the same species.
