4363. The skull of a species of Canis, called the Falkland Island Fox. 



It agrees in size with that of the Jackal, and, like it, differs from the skull of the Fox in 

 the greater convexity and expanse of the frontals. The hinder ends of the nasals, as in 

 No. 4361, are more nearly on a level with the maxillaries. The second lower premolar is a 



little further removed from the third.

4364. The skeleton of an Arctic Wolf (Canis Lupus). 



The vertebral formula is : 7 cervical, 13 dorsal, 7 lumbar, 3 sacral, and 15 caudal. Eight 

 pairs of ribs articulate directly with the sternum, which consists of eight bones. The last 

 cervical has the transverse process imperforate. The eleventh dorsal vertebra is that towards 

 which the spines of the other trunk-vertebrae converge. Metapophyses begin to be developed 

 on the eighth dorsal, and are continued to the fourth lumbar vertebra. The bones of the 

 extremities correspond in type with those of the Fox, but have more robust proportions.

4365. The skull of a large male Wolf (Canis Lupus). 



Like the Jackal, it differs from the Fox in the median depression and transverse convexity 

 of the frontal region produced by the bending down of the postorbital processes ; in the greater 

 posterior extension of the nasals, as compared with the maxillaries ; and in the encroachment 

 of the lacrymal on the face. The frontal bones preserve a more uniform breadth than in the 

 Jackal, being less expanded posteriorly where they join the parietals. The last true molar is 

 wanting in the lower jaw of this specimen.

4366. The skull of a male Wolf (Canis Lupus). 



Presented by Sir Stamford Raffles, P.Z.S. 



4367. The skull of a male Arctic Wolf (Canis Lupus). 



It corresponds in size with the preceding specimen, but the interorbital part of the frontals 

 is rather less convex transversely. 

 From Melville Island.

4368 . The skull of a Wolf ( Canis Lupus) . Mus. Brookes. 



4369. The skull of a female Wolf (Canis Lupus). Purchased. 



4370. The skull of a female Arctic Wolf (Canis Lupus). 



The frontal bone exhibits partial fractures, which have been healed. The tympanic bull* 

 has been laid open, showing the very oblique inner termination of the short and wide meatus
