femur. The slender fibula closely adheres to the lower half of the tibia. The hallui is re- 

 duced to a minute rudiment of its metatarsus. A few of the anterior caudal vertebrae have 

 haemapophyses : the supporting processes or ' hypapophyses ' are developed from a greater 

 number. The sacrum is remarkable for its sudden diminution of size, as compared with the 

 lumbar vertebrae, and only the first sacral vertebra articulates directly with the iliac bones.

4329. The skull of the Common Fox (Canis Fulpes). 



The paroccipital is triangular and applied to the back part of the acoustic bulla, but is 

 smaller and thicker than in the Paradoxuri, and stands off more from the bulla. The ali- 

 sphenoid articulates with the parietal. The interparietal, which has anchylosed with the 

 superoccipital, penetrates the posterior interspace of the parietals. The nasal processes of 

 the maxillaries are truncate, and terminate on the same transverse line as the nasals. The 

 maxillaries directly articulate with the middle part of the nasals. The dental series is com- 

 plete on the right side of this cranium.

4330. The skull of the Common Fox (Cants Fulpes). 



The base of the cranium is mutilated : the dental series is entire. The teeth have been 

 removed from the right half of both upper and lower jaws, and are separately displayed. The 

 symbols indicate their nature according to the TABLE OF SYNONYMS. 



Purchased. 



4331. The skull of a female Fox (Canis Fulpes). 



The dental system is complete : the calvarium has been removed to show the bony tento- 

 rium, which appears to be developed from the superoccipital. 



Purchased. 



4352. The skull of the Black Fox (Canis Fulpes}. 



This is a large variety of the common species. The teeth and the sutures correspond with 

 those in No. 4329.

4333. The skull of the Italian Fox (Canis melanogaster). 



Like the Isatis (No. 4335), the maxillaries articulate with a smaller proportion of the nasals 

 than in the Common Fox : this difference is well seen by comparing the present skull with 

 that of the female of the Common Fox (No. 4331), in which the muzzle is absolutely shorter. 

 The canines are longer and more slender in the Italian Fox. The accessory tubercles of the 

 premolars are better marked. This species or variety is more frugivorous than the northern 

 one, and plunders the vineyards at the wine season.
