26746. The distal two-thirds of the right ulna; from the Lower 
Miocene of Allier. This specimen is very similar to, but 
slightly smaller than, an ulna figured by Filhol in the 
Ann. Sci. Géol. vol. x. pl. xiv. fig. 3; it indicates a con- 
siderably smaller form than the humerus, No. 26744, and 
its specific reference is provisional.

26747. The acetabular portion of the right innominate; from the 
Lower Miocene of Aller. 
Pomel Collection. Purchased, 1851. 
30988. The proximal extremity of the right femur ; from the Lower 
Miocene of Allier. This bone indicates an animal of 
about the same size as that to which the humerus No. 
26744 belonged. Bravard Collection. Purchased, 1852. 
26745. The proximal half of the left femur; wanting the great 
trochanter; from the Lower Miocene of Allier. This 
specimen is of about the same size as the femur of Canis 
‘lupus; and is very similar to a specimen figured by Filhol 
in the Ann. Sci. Géol. vol. x. pl. xv. fig. 5. 
Pomel Collection. Purchased, 1851. 
43994. The shaft of the left femur; from the Lower Miocene of 
Tangy, Aller. This bone is somewhat larger than the 
femur of Canis lupus. Purchased, 1872. 
30995. The right astragalus; from the Lower Miocene of Allier. 
This specimen is much larger than the astragalus of Canis 
lupus, and somewhat larger than a specimen figured by 
Filhoi in the Ann. Sci. Géol. vol. x. pl. xvi. fig. 4; its 
specific determination is open to doubt.

Amphicyon ambiguus, Filhol '. 
This is a large species, distinguished by the transversely elongated 
form of the first and second upper true molars, and the minute size 
of m. 3, which is evidently in course of disappearance. 
Hab, France. 
M. 1686. Fragment of the left maxilla, containing the carnassial, 
the first and second true molars, and the alveolus of the 
third true molar; from the Upper Eocene of Bach, near 
Lalbenque (Lot), France. This specimen agrees precisely
