ANOPLOTHKR1IDJE. 199 



Caylux (Tarn-et-Garonne), France, and is in the posses- 

 sion of Dr. Filhol. The length of the space occupied by 

 the seven cheek-teeth is 0,110, and that by the three 

 true molars 0,057. Mnde in the Museum, 1885. 



M. 2142. Fragment of the left maxilla of an immature individual of 

 the same variety as the last ; from the Upper Eocene of 

 Caylux. The length of the space occupied by the last 

 three milk-molars is 0,054, or less than in the correspond- 

 ing specimen of A. secundarium, No. 30607. The first 

 true molar is rather larger than in No. 30708, its length 

 being 0,017, as against 0,015, the latter dimension agree- 

 ing with that of the specimen described by Filhol 

 (op. cit.). Purchased, 1885. 



30608. Fragment of the right maxilla of the intermediate variety ; 

 from the Upper Eocene of Debruge. This specimen shows 

 m- 2 and m. 3, in a partially worn condition, which are 

 slightly larger than in No. 30708, and make a nearer 

 approach to the brachydont form. The length of the space 

 occupied by the three true molars in a very similar speci- 

 men from Caylux, in the collection of M. Filhol, measures 

 0,056. Bravard Collection. Purchased, 1852. 



M. 2141. Fragment of the right maxilla of the more brachydont 



(Fiy.) variety, containing the last five cheek-teeth, in a partially 



worn condition; from the Upper Eocene of Caylux. In 



this specimen, which is figured in the accompanying 



woodcut (fig. 26), the outer surfaces of the external cusps

are inclined inwardly to an extreme extent, and the valleys 

 are very shallow. The length of the space occupied by
