the nape, on which the hair has a downward direction. On the 

 chest the hair passes upwards and outwards, and forms a ridge 

 where it meets the hair from the nape ; this ridge thus forms the 

 dividing line between the red and white fur, the two colours being 

 sharply defined. A similar but larger ridge is formed between 

 the hind limb and butt of the tail ; this does not, however, 

 separate the colours.

Skull. — Massive, with a short facial portion ; muzzle broad and 

 inflated, the nasal chamber wider than deep ; nasals moderate, 

 their greatest combined width 2 5 and their central width 3*1 

 times in their length. Ascending process of premaxilla greatly 

 expanded above, the naso-premaxillary suture one-half longer 

 than the naso-maxillary. Interorbital region not inflated, the 

 supra-orbital edges very pronounced, with a well marked concavity 

 between them. Inter-temporal constriction great, the least trans- 

 verse breadth equal to the posterior breadth of one of the nasals. 

 Opening of lacrymal canal bounded in front by the maxillary. 

 Palatal foramina slightly longer than M^, they extend backwards 

 to the maxillo-premaxillary suture, the maxillary forming their 

 posterior border. Anterior palate not very broad, its least width 

 2 '5 in the diastema, its edges marked but not acute. Palate very 

 complete, the invariable foramina on the palato-maxillary suture 

 and two or three small holes in the palatine excepted. Rami of 

 mandible short, deep, and thick ; the horizontal and ascending 

 portions of each form almost a riglit-angle. 



Teeth. — The incisor series are relatively shorter than in M. 

 (jiganteus. There is an external notch in I'', and faint trace of 

 one anterior to it. This tooth is almost as long as I' and P com- 

 V)ined. The molar series are markedly bent inwards anteriorly ; 

 each tooth has a small anterior ledge, in the fourth molar it is 

 connected with the first main ledge by a short bridge ; this 

 bridge is scarcely traceable in the other teeth ; the usual trans- 

 verse ledges are well developed, as are also the connecting ridges. 

 Anterior cheek teeth deciduous. The lower incisors are below
