96 CARNIVORA. 
Palzoprionodon, sp. 
Hab. France. 
M.1371. The greater portion of the left ramus of the mandible, 
containing the canine and all the cheek-teeth except 
pm.1; from the Upper Eocene of Caylux (Tarn-et- 
Garonne), France. In this specimen the space occupied 
by the cheek-teeth is the same as in No. M.1370; but 
pm. 2 is larger, the crowns of the other cheek-teeth lower, 
and the ramus of the jaw considerably more slender. 
These distinctive characters are not improbably of specific 
value. Purchased, 1884. 
M. 1373. The greater portion of the left ramus of the mandible; 
from the Upper Eocene of Caylux. This specimen, which 
is in every respect similar to the last, contains. the last 
three cheek-teeth and the alveoli of the first three pre- 
molars and the canine. Purchased, 1884. 
Genus STENOPLESICTIS, Filhol’. 
Dentition :—I. = C. = Pm. - M. 5. The present genus connects 
Paleoprionodon with Cynodictis; and also presents an approxi- 
mation to the Mustelide. In typical forms the lower carnassial has 
a distinct inner cusp, but this disappears in some varieties ; the last 
lower premolar has fore-and-aft talons. The characters of the 
upper dentition will be gathered from the description of the speci- 
men noticed below. 
Stenoplesictis cayluxi, Filhol”. 
Hab. France. 
M. 1723, The cranium, imperfect anteriorly and posteriorly ; from 
(Fig.) the Upper Eocene of Caylux (Tarn-et-Garonne), France. 
A specimen of the cranium has been described by Filhol in 
the Ann. Soc. Sci. Phys. Nat. Toulouse, 1882, pp. 66-7, 
but is not figured. The present specimen, which is repre- 
sented in the accompanying woodcut (fig. 9), agrees pre- 
cisely with the description of the type specimen; the 
length of the space occupied by the cheek-teeth being 
0,0255 in the present and 0,027 in the type specimen.
