Head, body, and limbs not definably different from th ose of 

 B. gaimardl and B. penicillata. There is, however, sometimes an 

 indistinct indication of a ■whitish stripe across the hip, absent in 

 other species. Hands and feet white or very pale brown ; hairs of 

 feet long, bristly, nearly or quite hiding the claws. Tail coloured 

 like the back, the hairs on the upperside, although longer than 

 elsewhere, not forming a distinct crest, and not or scarcely darker ■ 

 towards the end. Tip of tail apparently always white for from halt 

 an inch to two inches. Underside of tail white or pale brown. 



Skull short and broad, with a very short conical muzzle. Nasals 

 (PI. XIV. fig. 7) small, their lateral edges sinuous, and their 

 posterior evenly bowed backwards ; their greatest breadth rather 

 less than half their length. Supraorbital edges sharp and angular, 

 parallel to each other. Posterior palatine vacuities extending for- 

 wards to the middle or front of m.' Bullae (PL XIV. fig. 8) enor- 

 mously large and swollen, especially anteriorly, but varying very 



With five right upper molars.
