316 ADDENDA. 



The following specimens were obtained from the Upper Eocene of 

 Debruge, near Apt (Vaucluse*) ; and belong to the Bravard 

 Collection (Purchased, 1852). 



30682, 30703. Two specimens of the distal portion of the humerus. 

 30690. The greater part of the left ulna. 



30693-5. Three imperfect specimens of the radius. Each of these 

 bones exhibits three large knobs near the middle, and a 

 fourth close to the distal extremity of the inner (preaxial) 

 border ; which probably indicate the existence of warts, 

 or callosities, on this side of the limb. The distal knob is 

 exhibited in a specimen figured in De Blainville's ' Osteo- 

 graphie,' Genus Anoplotherium, pi. v. 



30686-7. Two specimens of the calcaneum. 



30676-7-8, 30680-1. Several specimens of the astragalus. 



Genus ANOPLOTHERIUM (page 188). 

 Anoplotherium commune (page 189). 



M. 1751. Part of the left ramus of the mandible containing the 

 last five cheek-teeth ; from the Upper Eocene of Caylux 

 (Tarn-et-Garonne), France. This specimen agrees pre- 

 cisely with the Yaucluse jaw, No. 26787 (p. 191). 



Purchased, 1884. 



It. 1779. Part of the left ramus of the mandible, showing mm. 4 ; 

 from, the Upper Eocene of Caylux. Purchased, 1884. 



M. 1814 a. The fourth left lower milk-molar, in a much-worn con- 

 dition ; from the Upper Eocene of Bach, near Lalbenque 

 (Lot), France. Purchased, 1884. 



M. 1844. The left astragalus of a large Anoplotherium ; from the 

 Upper Eocene of Caylux. This specimen is wider and 

 shorter than the astragalus of the so-called Eurytherium 

 latipes (page 193) ; its distal width being 0,056, and its 

 length about 0,069. In the absence of any decided differ- 

 ence in the dentition of the Caylux, Vaucluse, and Paris 

 specimens, it seems very doubtful if this variation can be 

 regarded as of specific value. Purchased, 1884.
