TRAQTTLIDJE. 151 



cheek-teeth, in an almost unworn condition ; from the 

 Upper Eocene of Caylux. Purchased, 1884. 



M. 1426. Fragment of the left maxilla, containing the last five 

 cheek-teeth, in a well-worn condition ; from the Upper 

 Eocene of Caylux. Purchased, 1884. 



M. 1423. Fragment of the left maxilla, containing the last four 

 cheek-teeth, in a partially worn condition ; from the Upper 

 Eocene of Caylux. There is a distinct cingulum to the 

 true molars in this specimen. Purchased, 1884. 



M. 1501. Fragment of the left maxilla, containing the three pre- 

 molars, in a well-worn condition ; from the Upper Eocene 

 of Caylux. Purchased, 1884. 



M. 1429. Fragment of the right maxilla, containing pm. 4 and m- 1 ; 

 from the Upper Eocene of Caylux. Purchased, 1884. 



M. 1414. Part of the right ramus of the mandible, containing the 

 last four cheek-teeth ; from the Upper Eocene of Caylux. 

 This specimen agrees precisely with the nearly complete 

 left ramus figured by Filhol in the Ann. Sci. Geol. vol. viii. 

 pi. xi. fig. 265, and exhibits the characteristic slender 

 form. The length of the space occupied by the three true 

 molars is 0,033, the length of m . 3 0,014, the depth of the 

 jaw in front of pm. 4 0,0135, and behind m. 3 0,017. 



Purchased, 1884. 



The following limb-bones from the Upper Eocene of Caylux probably 

 belong to Prodremotherium, or some of the allied genera. Pur- 

 chased, 1885. There are other specimens in the Collect-ton. 



M. 2236. The right humerus, wanting the head. 



M. 2234. The left radius and ulna. 



M. 2235. The right radius. 



M. 2240. The left femur. 



M. 2239. The left tibia, perhaps associated with the last. 



M. 2241. Two imperfect specimens of the metacarpus.
