MUSTELID.E. 185 



name croizeti should stand for the species, on the assumption that 

 the three forms are the same. In his quotations from Pomel, Filhol 

 (p. 131) has, however, given Pomel's description of P. lemanensis as 

 that of P. croizeti, and that of P. croizeti (p. 134) as that of P. lema- 

 nensis. According to Pomel's original description, it is P. lemanensis 

 that is stouter than P. croizeti ; but as Filhol has reversed the 

 two descriptions, it of course happens that P. croizeti is the stouter 

 species according to him. It appears, however, that the stouter 

 type of skull figured by Filhol under the name of P. rolusta, var. 

 croizeti, does agree more nearly in relative size with the type 

 mandible of P. croizeti, Pom., than does the slighter skull figured by 

 Filhol under the name of P. lemanensis ; and it therefore seems well 

 to provisionally adopt Filhol's identifications, although they appear 

 founded on a misconception. On this view P. croizeti will be (con- 

 trary to Pomel's original definition) a larger species than P. lema- 

 nensis. 



26702. The greater portion of the right ramus of the mandible, 

 (Fig.) containing the last two premolars and the carnassial, 

 and the alveoli of the other cheek-teeth and the canine ; 

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

 France. This specimen is the type of the species, and is 

 figured by Pomel in the Bull. Soc. Ge'ol. France, ser. 2, 

 vol. iv. pi. iv. fig. 4. Pomel Collection. Purchased, 1851. 



31022. The hinder part of the cranium, containing the left true 

 molar ; from the Lower Miocene of St. Gerand-le-Puy. 

 This specimen agrees with the cranium figured by Filhol 

 in the Ann. Sci. Geol. vol. x. pi. xxi. figs. 3, 4, 5, with 

 the exception that the temporal ridges are less closely ap- 

 proximated, this character probably depending to a great 

 extent on age. As mentioned above, these two specimens 

 may be provisionally referred to the present species.
