THE SIFAKAS. 103 



Characters. Muzzle very broad and naked ; nose-pad wide ; 

 inside of ears naked. Face, top of head, sides of neck, and 

 throat, deep brownish-black ; muzzle black ; a band across the 

 temples, and a streak down the nose, white. Ears black inside, 

 fringed externally with white ; neck and upper surface white, 

 washed with rust-colour on the limbs and root of the tail. Tail, 

 hands, and feet, pure white. Under side rich orange-red, 

 darker across the chest ; inside of limbs white, washed with 

 rufous. Of the same size as P. verreauxi. 



Cranium larger in all its parts than in other species. Nasal 

 bones elongated beyond the incisor teeth ; nose very flat, this 

 being due to the large air-cavity (called false nose) in the jaw-bone 

 below, connected with the nose. The length and breadth of the 

 muzzle gives a peculiar expression to the face of P. coronatus. 



This species, like the preceding, is subject to considerable 

 variation. 



The whole head is sometimes grey, washed with rufous ; 

 the upper surface and root of the tail white, flushed with rust- 

 colour. 



In examples living further in the interior than the habitat 

 of the type (Bay of Bembatoka), the back is more rufous, the 

 neck has a large grey or brown patch, and the chest is very dark 

 brownish rust-colour. The abdomen and the inner sides of the 

 limbs are bright red. 



Distribution. This species occurs on the north-west coast of 

 Madagascar, between the Bay of Mozamba to the north and 

 the River Manjaray on the south, ranging over the country to a 

 considerable distance into the interior. The lighter-coloured 

 specimens come from the more northern range of the species, 

 while the more brightly-marked varieties have been obtained
