while pm. i has but a single root. Casts of fragments of mandibles 

 from Switzerland in the Museum labelled Palceomeryx scheucJtzi ri 

 agree precisely with the French specimens, and have accordingly 

 been referred to the present species. The upper true molars are 

 almost indistinguishable from those of A. lemanensis. 

 Hob. Europe. 



M. 2170. The right half of the palate, with the six cheek-teeth; 

 from the Lower Miocene of St. Gerand-le-Puy (Ailier), 

 France. The length of the space occupied by the six 

 teeth is 0,0563 ; the length of the corresponding space in 

 the specimen described and figured by Filhol, in the Ann. 

 Sci. Geol. vol. xi. art. 1, p. 57, pi. xvi. fig. 4, being 0,054. 



Purchased, 1885. 



21928. Part of the right maxilla containing the last five cheek-teeth, 

 in a well-worn condition; from the Lower Miocene of 

 Ailier. This specimen agrees precisely with the one 

 figured by Filhol in the Ann. Sci. Geol. vol. xi. pi. xvi. 

 tig. 4 ; the length of the three true molars being 0,0295, as 

 against 0,029 in Filhol's specimen. The large develop- 

 ment of the inner tubercle of pm- 3 distinguishes the 

 specimen from A. lemanensis. 



Croizet Collection. Purchased, 1848. 



34196. Fragment of the right maxilla, containing the three true 

 molars in an unworn condition ; from the Lower Miocene 

 of Ailier. The teeth agree precisely with those of the 

 last specimen. Bravard Collection. PurcJiased, 1852. 



34196 a. Fragment of the left maxilla, containing the three true 

 molars, in an unworn condition ; from the Lower Miocene 

 of Ailier. The teeth are slightly smaller than in the last 

 specimen. Bravard Collection. Purchased, 1852. 



27598. Fragment of a right maxilla provisionally referred to this 

 species, showing three milk-molars and m. 1 ; from the 

 Lower Miocene of Ronzon, near Puy-en-Velay (Haute 

 Loire), France. The first molar is larger than in Gelocus 

 communis, and agrees with the corresponding tooth of the 

 present species ; there is no sign of mm. 1. 



Croizet Collection. Purchased, 1848. 



M. 2171. Part of the loft raraus of a mandible, showing the four 

 premolars, m. 1 and m. 2, probably belonging to a small 

 specimen of the present species ; from the Lower Miocene 

 of St. Gerand-le-Puy. Purchased, 1885.
