94 CARNTVORA. 



28121. A metatarsal and a proximal phalangeal; from the Lower 

 Pliocene of Cuuron (Vaucluse), France. 



Bravard Collection. Purchased, 1852. 



Ictitherium robustum (P. Gervais 1 ). 

 Syn. Thattasictis robusta, P. Gervais 2 . 



Ictitherium viverrinum, Roth and Wagner 3 . 



Hob. Europe. 



49676. Cast of the cranium and mandible. The originals are in the 

 Museum at Munich, and were obtained from the Lower 

 Pliocene of Pikermi, Attica. Purchased, 1879. 



Genus PAKffiOPRIONODON, Filhol 4 . 

 Dentition : I. L C. ?, Pm. \, M. -,. The second lower molar is 



3" 1" 4 ? & 



small, and there is a minute inner cusp to m . 1, by which the genus 

 is distinguished from the musteline genus Plesiictis. The genus 

 seems to pass almost insensibly in one direction into the feline genus 

 Pseudcelurus, and in another through Stenoplesictis to Cynodictis. 

 The lower teeth are exceedingly like those of Prionodon. 



Palseoprionodon mutabilis, Filhol 9 . 

 Syn. Pksiogale mutabilis, Filhol. 



Palceoprionodcni lamandini, Filhol. 

 Palceoprionodon lamandini, var. mutabilis, Filhol. 



History. In 1877 Filhol (Ann. Sci. Geol. vol. viii. art. I, p. 42, 

 vol. vii. pi. xxv. figs. 6 110-113) described and figured certain 

 mandibles of a viverrine Carnivore under the name of Plesiogale 

 mutabilis. In 1880 (Compt. Rend. vol. xc. p. 1579) he described 

 another lower jaw under the name Palceoprionodon lamandini. In 

 1882 (Ann. Soc. Sci. Phys. Nat. Toulouse, p. 68, pi. iv. fig. 4) the 

 same writer figured and fully described the lower jaw on which that 

 species was founded. At the same time (ibid. p. 74) he came to the 

 conclusion that the so-called Plesiogale mutabilis was only a variety 

 of Palceoprionodon lamandini, and proposed to call it by the name 

 of Palceoprionodon lamandini, var mutabilis. It is clear, however,
