2. PBEAMELES. 237 



bright and glistening, but sometimes almost obsolete. Top of head 

 dark brown, owing to the greater proportion of bristly hairs 

 present there. Muzzle long and narrow, the distance from the tip 

 of the nose to the anterior canthus of the eye considerably exceed- 

 ing that from the latter to the ear. Ears small, laid forward they 

 do not reach halfway to the eye, their inner margin evenly convex, 

 their outer nearly straight for its upper two thirds, then markedly 

 convex ; metatragus about 3 millim. in length, triangular, pointed, 

 its tip thinly haired. Chin, chest, and belly variable, either white, 

 mixed brown and white, or, brown and yellow. Arms, legs, and 

 feet brown, hands white. Hind feet (PL XXI. fig. 6) very variable 

 in size, but generally in the male 60 millim. or more, and in the 

 female from 50 to 60 millim. long ; soles wholly naked, their 

 surface without separated pads, uniformly coarsely granulated. 

 Mammae 8. 



SIcuU (PL XXII. fig. 3) large, long and narrow, but strongly 

 built. Muzzle very long, the distance from the tip of the pre- 

 maxillse to the front of the orbit from 38 to 45 millim. Nasals 

 long, their greatest breadth going 5^ or 6 times in their length. 

 Interorbital space smooth, rounded, paraUel-sided, its edges evenly 

 rounded. Lacrymal bone smoothly rounded externally, not ridged. 

 Zygomatic arches but little expanded. Palate comparatively 

 perfect, the only vacuities, besides the anterior palatine foramina, 

 being a single pair opposite the first two or three molars. Walls of 

 foramen rotundvm prolonged into a distinct bony tube, opening 

 forwards. Bullae exceedingly small, generally imperfect, the tym- 

 panic ring not ossified to the bullae, and therefore usually lost in 

 cleaned and dried skulls. Lower jaw long and slender, but the 

 ascending process convex forwards as usual. 



Teet% small and delicate. Upper incisors only 4 in number ; i.' 

 always absent ; the others broad and flat ^ i.* not markedly shorter 

 than i.^ and i.' Canine very short and small, never longer than 

 and rarely as long as p.'' ; its distance behind i.* froni 6| to 7g 

 miUim., and in front of p.' about 3 mUlim. Premolars light and 

 slender, evenly increasing in size backwards ; diastema between p.' 

 and p.' about 2 millim. ; p.* with an internal basal thickening. 

 Molars light, triangular, their internal portion very much shorter 

 antero-posteriorly than their external, so that broad V-shaped gaps 

 are left between them. Lower teeth as usual; canine about the 

 length of p.'
