CARNIVORA. 
of Gulo diaphorus. There are four premolars, two of 
which have fallen from their alveoli. 
Enniskillen Collection. Purchased, 1882. 
37355. Cast of part of the right ramus of the mandible, containing 
the broken canine, the alveolus of pm. 1 (so determined 
from the last specimen), the last premolar, the carnassial, 
and the alveolus of m.2. The original is from the Lower 
Pliocene of Pikermi, Attica, and is in the Munich Museum ; 
it is figured by Roth and Wagner in the Abh. Math.-phys. 
Cl.k.-bay. Ak. Wiss. vol. vil. pt. 2, pl. vii. figs. 1, 2, under 
the name of Gulo primigenius. There are no signs of 
pm.2 and pm.3 in this specimen, which agrees in this 
respect with the mandible figured by Gaudry in the ‘ Ani- 
maux Fossiles et Géologie de l’Attique,’ pl. vi. figs. 1, 2, 
under the name of Metarctos diaphorus; the reference of 
this form to the same species as the Eppelsheim jaw being 
apparently somewhat provisional. In the Pikermi form 
the last premolar is larger than in the Eppelsheim, but 
in other respects the two are precisely similar in the form 
of the jaw and teeth. Purchased, 1863. 
49675. Casts of the associated cranium and mandible. ‘The originals 
of these specimens are from the Lower Pliocene of Pikermi 
and are preserved in the Munich Museum. They are 
figured by Wagner in the Abh. Math.-phys. CL k.-bay. Ak. 
Wiss. vol. vill. pl. vi. fig. 13, as Pseudocyon robustus. The 
cranium shows the incisors and the canine: behind the 
latter there is a small tooth which, judging from the 
analogy of the lower jaw, should probably be regarded as 
pm.1; there is a small interval, without any trace of 
alveoli, between this tooth and the carnassial, the latter 
being followed by the two true molars. The mandible 
shows the incisors and the canine, and contains pm. 4, m. 1, 
and m.2. There is no trace of the alveolus of pm. 1, which 
is present in No, 37355. 
The retention of the first premolar in both jaws, after 
the disappearance of the second and third teeth in both 
jaws, is analogous to the condition prevailing in Ursus 
and Hycnarctos. Purchased, 1879.
