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) inthe 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 toa 
considerable distance into the interior. ‘The lighter-coloured

while the more brightly-marked varieties have been obtained
