COQUEREL’S SIFAKA. PROPITHECUS. COQUERELI. 
(Plate XT.) 
Has the facenaked and black, but the centre of the nose white; 
the ears showing as black points amid the white hair; head and 
back of neck white, slightly washed with yellow ; outer side of 
arm and fore-arm dark maroon-red, the lower border fringed 
with long white hair; a maroon patch on the upper and outer 
surface of the thighs, lighter on the chest and central part of 
the belly. Loins dark rusty-grey ; hands white; tail rusty-grey. 
Distribution.— Verreaux’s Sifaka, witii its two varieties, is con- 
fined to the small thin woods on the sandy and almost rain-less 
plains along the western and southern coasts of Madagascar. 
The type-form is found, alone, and unassociated, in the exten- 
sive plains of Mesozoic geological formation—between the 
southern base of the eastern range of mountains and the River 
Tsidsubon, which flows into the sea on the west coast. Von 
der Decken’s Sifaka inhabits the middle of the west coast, while 
Coquerel’s Sifaka has its home further to the north. It occupies 
the area between the south side of Narendry Bay and the north 
side of Bembatoka Bay, the Betsiboka River being its extreme 
southern limit. 
Though first observed by Flacourt, and described by him in 
1661, Verreaux’s Sifaka remained practically unknown from 
that time till re-discovered by M. Grandidier in 1867.
