Size medium, form light and graceful. Ehinarium (PI. XI. fig. 3) 

 ending some way from the mouth, opening at the top of a distinct 

 cleft running down to the upper lip, the lip itself much more 

 developed in front than usual. Fur rather short in mainland, 

 longer in island specimens. Underfur thick and soft, dark slaty 

 grey. General colour grizzled grey, with rufous shoulders. Pace 

 and head uniform grey ; an indistinct white cheek-stripe generally 

 present. Ears long in mainland, short in island specimens, uniform 

 dark grey, brown behind. Neck with an iU-defined central brown 

 band passing down from between the ears to the back, sometimes 

 scarcely Yisible, especially in immature specimens. Shoulders, sides 

 of neck, and arms rufous, very variable both in extent and tint ; 

 these parts sometimes (? in winter) grey, with scarcely a tinge of 

 rnfous. Back grizzled grey, a rufous tinge becoming again apparent 

 on the flanks, lower rump, and hind legs. Chin, chest, and belly 

 white or greyish white, generally well defined. Hands, feet, and 

 tail grey, becoming nearly black at their extremities. 



Skidl (PI. VII. fig. 3) strongly built. Facial portion propor- 

 tionally small ; facial index low. Muzzle short, rather narrow 

 behind, and therefore not so markedly conical as in some of the 

 other species. PremaxillsB oblique ; naso-premaxillary about equal 

 to naso-maxillary suture. Nasals short, expanded behind, their pos- 

 terior edge sinuous, bowed backwards, but their detailed shape very 

 variable, ordinarily as in the figure. Interorbital edges parallel, 

 sharp, with a tendenc}', in mainland specimens only, to form rudi- 

 mentary postorbital processes; intertemporal constriction scarcely 

 observable. Palatal foramina small. 



Teeth. Incisors small and light. I.' slanting forwards, its notch 

 decidedly behind its centre. P.* (PI. X. fig. 10) very small, about 

 the length of m.' or m.^, its posterior breadth markedly greater than 

 its anterior, the inner ledge obsolete in front ; two vertical grooves 

 on its outer side ; its anterior end rounded. Molars strong and 

 with well-developed cusps and ridges in mainland specimens ; but in 

 those from the islands the molars are small and narrow, and the 

 cusps and ridges low and blunt.
