22 CARNIVOBA. 



France. This specimen agrees precisely with the type 

 mandible figured by Pilhol in the Ann. Sci. Geol. vol. vii. 

 pi. xxxii. fig. 160. The following are the dimensions of 

 the type and the present specimen, viz. : 



Type. No. 26749. 



Length of pm. 3 0,017 0,016 



pm. 4 0,0175 0,0161 



m . 1 0,009 0,010 



,. m. 2 0,014 0,0141 



m. 3 0,021 0,023 



Space occupied by last five teeth .. 0,080 0,079 



Interval between canine and hinder 



border of m. 3 0,107 



Depth of jaw at m. 1 0,043 0,040 



The present specimen shows the first and second pre- 

 molars, which are wanting in the type ; the crown of the 

 first premolar is very low, while that of the second is not 

 very high and is elongated antero-posteriorly. The canine, 

 of which the summit is broken on , is relatively short and 

 thick. There is but one mental foramen.

28203. The cranium and mandible in a much-crushed condition ; 

 from the Upper Eocene of Debruge. This specimen is 

 important, as showing the association of the cranium and 

 mandible, although all the mandibular teeth are wanting, 

 except the canine and pmT2 ; the form of the mandible 

 agrees precisely with that of the last specimen. The last 

 upper premolar has a small anterior talon. The interval 

 between the canine and the hinder border of the last true 

 molar is 0,090, and the antero-posterior diameter of the 

 canine is 0,017. This specimen is the type of Bravard's 

 Eutemnodus. Bravard Collection. Purchased, 1852. 



28172. The mandible, wanting the symphysis, and showing all the 

 cheek-teeth except pm. 1 ; from the Upper Eocene of 

 Debruge. Bravard Collection. Purchased, 1852. 



26756. The greater portion of the left ramus of the mandible, with 

 the teeth much worn ; from the Upper Eocene of Vau- 

 cluse. Pomel Collection. Purchased, 1851. 



M. 1673. The hinder portion of the cranium of a Hycenodon, which, 

 from its large size, may probably be referred to the pre-
