disproportion of the cranium to the face is retained. The nasal processes of the maxillary 

 ascend a little beyond the nasals, and articulate with the hinder half of those bones, the inter- 

 posed anterior angles of the frontal being much less produced than in the Foxes. The pre- 

 maxillaries are relatively larger. The teeth have been removed and separately displayed, 

 from the left side of the upper and from the right side of the lower jaw ; the series is not 

 quite complete, but the alveoli demonstrate the same dental formula as in the rest of the 

 genus.

4359. The upper jaw, and part of the lower jaw, of the Cape Fox (Proteles La- 

 landii). 



The dentition of this singular genus, although corresponding with that of the genus Canit 

 in the deciduous series, deviates extraordinarily in the permanent state, especially in regard 

 to the molar series. In the present specimen there are i ^, c j^j-, three small and simple 

 premolars on the left side, and one on the right side of the upper jaw, two similar premolars 

 and the socket of a smaller premolar on the right side of the lower jaw, and two simple pre- 

 molars on the portion of the left ramus of the same jaw which is here preserved.

4360. The skull of the Jackal (Canis aureus). 



The interorbital part of the frontals is more convex than in the Fox. The hind points of 

 the nasals extend a little further back than the maxillaries, the nasal processes of which are 

 more pointed. The facial part of the skull is shorter and stronger.

4361. The skull of a Jackal (Canis aureus). 



It corresponds with the preceding specimen, and differs in the same particulars from the 

 Fox. The molar teeth, especially the carnassials, are relatively larger. 

 From the Himalaya Mountains.

4362. The skull of the Cape Jackal (Canis mcsomclais). 



It differs from the Indian Jackal by the minor development of the postorbitar processes ; 

 but this may depend upon the difference of age of the specimens compared, the temporal 

 ridges not having met above the parietal bones, and the interorbital portion of the frontals 

 not being so well defined ; but this portion differs from that in the Isatis and other foxes in 

 its greater degree of convexity, and the nasal bones, as in other Jackals, extend further back 

 than the maxillaries. The lacrymal also encroaches a little upon the face.
