154 EXTINCT AND VANISHING MAMMALS 



of hind limbs down to the heel also brown, joining the colour of the 

 upper surface, thus forming a continuous dark stripe along the 

 legs. Inner and upper surface of arms, thumb, and two following 

 fingers deep blackish brown; throat, chest, and greater part of 

 abdomen deep brown. Size perceptibly larger than that of Propi- 

 thecus verreauxi, with the tail longer. 



"A number of specimens, all perfectly alike in colour, were sent 

 to me by Mr. Last from the Antinosy country in south-west Mada- 

 gascar. The collector also found Propithecus verreauxi Grandid. 

 in the same country, some with the back much darker than others, 

 but no specimens in any way intermediate between it and P. majori." 

 (Rothschild, 1894, p. 666.) 



"There are four more skins exactly like the type in the Tring 

 Museum. 



"The original label only says 'Antinosy' (=Antanosy) country. 

 It would appear that this means the mountain range round and east 

 of Manansoa (23 3' S., 44 50' E.), where J. T. Last was collecting 

 in 1889. The specimens of true verreauxi collected by Last and 

 also labelled 'Antinosy country' are probably from the plains farther 

 west, and collected on the way to or from Tulear, on the S.W. coast. 

 Only the original series of this race is known." (Schwarz, 1931, 

 p. 424.) 



Perrier's Sif aka 



PROPITHECUS PERRIERI Lavauden 



Propithecus Perrieri Lavauden, Comptes Rendus Acad. Sci. [Paris], vol. 193, 

 no. 1, p. 77, 1931. ("Foret d'Analamera, situee au sud-est de Diego- 

 Suarez, dans le nord de Madagascar.") 



This Sifaka is known only from a few specimens collected in the 

 Forest of Analamera, which covers an area of 5,000 or 6,000 hectares. 



It bears some resemblance to Propithecus verreauxi coquereli of 

 western Madagascar but differs especially in its color. The entire 

 pelage is velvety black; ears small and glabrous; eyes brown. Head 

 and body, 500 mm.; tail, 450 mm. 



It may seem surprising that this species has remained unknown 

 until so recently. The explanation lies in the fact that both the 

 animal itself and the forest in which it lives are strictly taboo to the 

 local Antakara natives. They give it the name of "Radjako"; this 

 was the name of a legendary hero among their ancestors. Few 

 Europeans have penetrated the Forest of Analamera. (Lavauden, 

 1931, pp. 78-79.) 



G. M. Allen (1939t>, p. 133) regards the type specimen as "prob- 

 ably a melanistic individual of P. v. coquereli."
