men in the possession of Dr. Eilhol, the length of the 

 corresponding space is 0,057 ; the inclination of the outer 

 surface of the external cusps is slightly less in that speci- 

 men. The striking resemblance of the molars of the 

 present specimen to those of Hyopotamus is apparent from 

 ohe figure, and leads to the inference that Anopl 'other iwm 

 and Hyopotamus are closely connected. Purchased, 1885. 



30632. Part of the right ramus of the mandible, containing all the 

 cheek-teeth except pm. 1 and m . l ; from the Upper Eocene 

 of Debruge. This specimen agrees with the one figured 

 by Eilhol in the Ann. Sci. Geol. vol. viii. pi. xv. figs. 298 

 -9, under the name of Eurytherium secundarium, with 

 the exception of the slightly larger size of m . 3. The 

 length of the space occupied by the three true molars is 

 0,0615. Bravard Collection. Purchased, 1852. 



M. 1388. Fragment of the right ramus of the mandible, containing 

 mT2 and m. 3 ; from the Upper Eocene of Caylux. This 

 specimen agrees precisely with the last. Purchased, 1884. 



M. 2143. The right ramus of the mandible of a young individual, 

 containing the last milk-molar and the three true molars ; 

 from the Upper Eocene of Caylux. The length of the 

 space occupied by the three true molars is 0,061, the 

 length of ]^~3 0,027, and that of mm. 4 0,019; these 

 dimensions being almost identical with those of the speci- 

 men figured by Eilhol {op. tit.). Purchased, 1885. 



30363. The greater part of the right ramus of the mandible of a 

 young individual, agreeing very closely with the last, and 

 showing the incisors, canine, p m . 1, mm. 2, mm. 3, mm. 4, 

 and m7T ; from the Upper Eocene of Vaucluse. The 

 length of the space occupied by the three milk-molars is 

 0,055, and the length of m^Ti 0,018. 



Bravard Collection. Purchased, 1852. 



Foot-bones of the third largest tridactyle form. 



30600 d. Several of the bones of the right fore foot, comprising the 

 unciform, the three metacarpals, one proximal, and two 

 second phalangeals ; from the Upper Eocene of Debruge. 

 This specimen agrees well in size with A. cayluxense, the 

 extreme length of the third metacarpal being 0,086.
