that the name mutabilis has the priority and must stand for the 
species, the type of which will be the original Plessogale mutabilis ; 
the name 
lamandini, if employed at all, should be used in a varietal 
sense for the form with a large m. 2, figured in the Ann. Soc. Sci. 
Phys. Nat. Toulouse, 1882, pl. iv. fig. 4. 
Hab. France. 
M. 1643. 
M. 1369. 
Two specimens of part of the right ramus of the mandible, 
showing the third and fourth premolars, the carnassial, 
and the alveoli of m.2 and the other teeth; from the 
Upper Eocene of Bach, near Lalbenque (Lot), France. 
These specimens appear to agree precisely with the form 
figured by Filhol in the Ann. Sci. Géol. vol. vii. pl. xxy. 
figs. 112, 113, under the name of Plesiogale mutabilis. 
Purchased, 1884. 
The greater portion of the right ramus of the mandible, 
containing the canine and all the cheek-teeth except pm. I 
(of which the crown is broken off); from the Upper EKocene 
of Caylux (Tarn-et-Garonne), France. This specimen 
appears to agree precisely with the mandible figured by 
Filhol in the Ann. Sci. Géol. vol. vil. pl. xxv. figs. 110, 111, 
under the name of Plesiogale mutabilis, and that in the 
Ann. Soc. Sci. Phys. Nat. Toulouse, 1882, pl. iv. fig. 1, 
under the name of Paleoprionodon lamandini, var. muta- 
belis; both these specimens differing slightly from the 
preceding specimens. Purchased, 1884.

Hab. Kurope. 
M. 1370. 
M. 1644. 
The greater portion of the left ramus of the mandible, con- 
taining the canine and all the cheek-teeth ; from the Upper 
Eocene of Caylux. In this specimen the length of the space 
occupied by the last four cheek-teeth is the same as in No. 
M.1369 ; the interval between pm. 3 and the canine is, how- 
ever, considerably less, and pm.2 is smaller. The second 
true molar is small, and there is a distinct inner cusp to 
the carnassial. tt is not improbable that these differences 
should be regarded as of specific value. Purchased, 1884. 
Symphysial extremity of the left ramus of the mandible, 
very similar to the last specimen ; from the Upper Eocene 
of Bach. Purchased, 1884.
