FOSSIL CARNIVORA. 229 
the alveoli of C,, P,, P,, and fragments of P,, P,, and M,; a 
right half contains the canine, the premolars, and the molars. 
The small size of the examined object is very remarkable. 
According to Filhel (4, p. 12), ue, measures 5°5 and M, 8 mm. 
in length; however, I found that the corresponding teeth 
measure 4 and 5°5 mm. respectively. But it must be borne in 
mind that, according to Schlosser (4, p. 54), in the specimen of 
Cynodon gracilis in the Museum of Munich, M, is not quite 
as long as that of the specimen examined by Filhol, and that 
there is a possibility that this skull belonged to a female or 
to a small specimen. How widely the size of the skull of Car- 
nivora varies has been shown by Hensel (2). 
That we have here to do with Cynodon gracilis, and not with 
O. velaunus, C. aimardu, C. speciosus, or C. leptorhynchus, 1s 
evident, as all these, which also occur in the Phosphorites of 
Quercy, are larger than C. gracilis. 
The sutures between the maxillaries and the frontals, those 
between the latter and the nasals, those between the jugal and 
the maxillary, as well as the outlines of the lachrymal, and those 
of the orbitosphenoid are very distinct—showing that the 
specimen is young. ‘There is, however, a crista sagittalis (fig. 5). 
In Cynodon gracilis the canalis infraorbitalis opens above P*, in 
Cynodon leptorhynchus, according to Schlosser (5, p. 115), above the 
interspace between P* and P*, which probably depends on the 
greater length of the jaws of the latter. The nasals are very 
short, and consequently the anterior nares have an oblique 
direction as in Cynodictis gryei, and as in the last-mentioned 
animal the nasals stretch between the frontals above the 
maxillaries (1, pl. 19. fig. 58). Judging from the strength and 
direction of the preserved part of the jugal, the zygomatic arch 
seems to have been strong and wide, thus differing from that of 
Cynodon leptorhynchus, of which Schlosser states :—* Jochbogen 
schlank, wenig gekrummt” (5, p. 115). 
The upper incisors are separated by small gaps. The upper C 
measures 7-5 mm. in height; P* has one root, and stands at some 
distance from the canine. P? and P* are of the same form as 
P, and P,, but of smaller size. As to P*, it has a strong cingulum, 
as have the anterior premolars ; its anterior cusp is higher than 
the posterior. Only its labial side was to be seen, which was 
also the case with M' and M*. The height of the two latter teeth 
is 5 mm. (fig. 4). ving 
The lower jaw and its teeth have been most satisfactorily 
deseribed by Filhol (1, p. 120).
