34961 a. The cranium, in a much-damaged condition ; from the 

 Lower Miocene of St. Gerand-le-Puy (Allier), France. 

 This specimen, which is the type of PomePs Palceochcerus 

 suillus, shows the three true molars of both sides, pm. 4 

 on the right, and PPI- 3 and pm- 4 on the left side ; it also 

 shows the alveoli of the earlier teeth and the worn right 

 canine l . It is described by Filhol in the Ann. Sci. Geol. 

 vol. xi. art. 1, pp. 15-16. The length of the space occu- 

 pied by the three true molars is 0,034, and the interval 

 between m. 3 of opposite sides 0,022. The true molars are 

 indistinguishable in form from those of the last specimen, 

 but are slightly smaller ; all the cheek-teeth agree very 

 closely with those of the specimen figured by Gervais 

 (Joe. cit.), with the exception that pm. 4 has one instead of 

 two external tubercles ; this, according to Filhol, being a 

 variable character.

27593. Fragment of the left maxilla, containing mm. 3, mm. 4, and 

 m. 1, together with the detached m. 2 ; from the Lower 

 Miocene of Sauvetat (Puy-de-D6me), France. This speci- 

 men is noticed by P. Gervais in the Zool. et Pal. Fran- 

 gaises, 2nd ed. p. 184, and referred to H. waterhousei, on 

 the ground that the columns of the true molars are more 

 pyramidal than in the present species ; this is, however, 

 entirely due to their unworn condition, and as they agree 

 in size with the corresponding teeth of No. M. 2198, the 

 specimen is referred to the present species. The length of 

 m. 1 is 0,0115, and that of m. 2 0,0125.

M. 2199. Fragment of the right maxilla, containing m. 2 and m- 3, 

 together with several detached upper true molars ; from 

 the Upper Eocene of Caylux (Tarn-et-Garonne). As 

 these specimens are indistinguishable from the correspond- 

 ing teeth of the preceding specimen, they may at least 

 provisionally be referred to the same species. 



Purchased, 1885. 



34961 b. The greater part of the mandible in a somewhat broken 

 condition, showing the last four cheek-teeth; from the 

 Lower Miocene of Romagnat (Allier). This specimen 



1 The canine of a Palaomeryx or Amphitraguhis has been inserted in the 

 left side.
