THE TRUE LEMURS. 69 



mantled variety has the back of the neck, the shoulders and 

 interscapular region entirely black. Another form has the ears, 

 the ruff, and a bar across the muzzle extending over and in 

 front of the eyes, joining the ruff, pure white ; the fore-arms, 

 legs, a bar across the buttocks joining the thighs greyish-white ; 

 face, legs, and tail black ; a ring encircling the body like 

 a belt between the fore- and hind-limbs, yellowish-white ; rest 

 of body dark reddish-brown. A third variety has the ears, 

 ruff, and outer side of the arms and legs pure white ; the 

 flanks rusty-red, the rest of the body black. 



The Red-ruffed Lemur (Z. varius, var. ruber) is a very 

 well-marked variety of the same species, and may easily be 

 recognised by the ears, ruff and whole upper surface of body 

 being dark rusty-red, with the outer surface of thighs and legs 

 white; or, the ears, ruff and whole upper surface (except a 

 white patch on the back of the neck) may be dark brown, with 

 a white garter on each ankle ; otherwise it may be entirely 

 black. It is this variety which we have figured on Plate VII. 

 Distriljution. — Throughout the north-east of Madagascar. 

 Habits — The Ruffed Lemur, called by the natives " Vari- 

 kossi," has a loud, harsh and powerful voice, which can be 

 heard for a long distance.
