in the narrow bands of forests on the eastern slope of the moun- 

 tains (Milne Edwards and Grandidier, 1875, p. 300) . 



"It is stated to be rare" (Bennett, 1832, p. 22). 



G. M. Allen (1918, p. 515) records a specimen from Didy, south 

 of Lake Alaotra. 



Schwarz (1931, p. 422) mentions specimens from: Tamatave, 

 NE. coast ; Andragoloaka, SE. of Tananarive ; and Mananare, Bay of 

 Antongil. 



Silky Sifaka. Propitheque soyeux (Fr.) 



PROPITHECUS DIADEMA CANDIDUS Grandidier 



Propithecus candidus Grandidier, Compt. Rend. Acad. Sci. [Paris], vol. 72, 

 p. 232, 1871. ("Les forets au nord de la baie d'Antongil, sur la cote est 

 de Madagascar"; type locality restricted by Schwarz (1931, p. 421) to 

 "Sahambavany, N.E. coast" of Madagascar.) 



SYNONYM: Pr&pithecus sericeus Milne-Edwards and Grandidier (1872). 



FIG. : Milne Edwards and Grandidier, 18756, pi. 2. 



This Sifaka has a limited range in the northeast of Madagascar, 

 and its numbers are apparently few. 



It is distinguished from P. verreauxi by its entirely white color, 

 without black crown or ashy spot on the back (Grandidier, 1871, 

 p. 232). Muzzle bare, black, with spots of flesh color; pelage gener- 

 ally entirely white, with silky reflections and washed lightly with 

 yellow; hairs at base of tail and beneath claws rufous; various 

 intergradations between this subspecies and P. d. diadema observed 

 (Milne Edwards and Grandidier, 1875a, p. 301). Head and body, 

 620 mm.; tail, 400 mm. (Milne-Edwards and Grandidier, 1872, 

 p. 274). 



Schwarz (1931, pp. 421-422) records specimens from Sahamba- 

 vany, NE. coast, and from Antsompirina and Ansandrizina, NE. 

 coast (probably on the peninsula which forms the eastern border 

 of the Bay of Antongil). "The range of this race includes the 

 north-eastern coast ranges of the island from the region of Bemarivo 

 (14 16' 30" S.), which is the northernmost locality recorded, to the 

 Bay of Antongil ; I suppose the Tsingambala River, at the northern 

 end of the bay, will be found to separate the range of candidus from 

 that of diadema." 



The Silky Sifakas inhabit the narrow bands of forests covering 

 the eastern slope of the mountains in the northeast, between the 

 Lokoy River (13 miles south of Sambava) and the Bemarivo River 

 (10 miles north of Sambava). They go ordinarily in smaller bands 

 than their congeners; scarcely more than three or four are found 

 together. (Milne Edwards and Grandidier, 1875a, p. 302.) 



Elliot (1913, vol. 1, p. 171) is in error in placing the range in 

 northwestern, instead of northeastern, Madagascar.
