126 EXTINCT AND VANISHING MAMMALS 



According to Elliot (1913, vol. 1, p. 107), the range extends on 

 the west coast from Cape St. Vincent to Helville, in the vicinity of 

 the Bay of Passandava. 



Only five specimens are reported by Delacour (1932, p. 220) as 

 collected by the Mission Zoologique Franco-Anglo-Americaine of 

 1929-31. 



Geoffrey's Fat-tailed Lemur 



CHEIROQALEUS MEDIUS MEDIUS E. Geoffroy-Saint-Hilaire 



Cheirogaleus medius [E.] Geoffroy-Saint-Hilaire, Ann. Mus. Hist. Nat. [Paris], 

 vol. 19, p. 172, 1812. (Type locality not stated; restricted by Schwarz 

 (1931, p. 405) to "Ft. Dauphin, S.E. Madagascar.") 



SYNONYM: Opolemur thomasi Major (1894). 



FIGS.: E. Geoffroy-Saint-Hilaire, Ann. Mus. Hist. Nat. [Paris], vol. 19, pi. 10, 

 fig. 2, 1812; Major, 1894, pi. 1, fig. 1. 



Extremely little information is available concerning this lemur, 

 but it is evidently one of the less common of the Madagascar forms. 



Head broad; snout short; upper parts gray, with a wash of rusty 

 brown, the tips of the hairs silvery; a whitish band extending from 

 between the eyes to the naked nose-pad; a whitish half-collar on 

 each side of the neck; orbital ring and ears brownish black; under 

 parts, inner side of limbs, and hands and feet yellowish white. Head 

 and body of female, 232 mm.; tail, 195 mm. (Major, 1894, p. 20; 

 type description of Opolemur thomasi.) 



Major (1894, p. 20) records three specimens (as 0. thomasi) from 

 Fort Dauphin. "Nothing is known of the distribution . . . north of 

 Ft. Dauphin in eastern Madagascar" (Schwarz, 1931, p. 405). 



The Mission Zoologique Franco-Anglo-Americaine of 1929-31 col- 

 lected nine specimens (Delacour, 1932, p. 220). 



"These little lemurs are apparently entirely nocturnal .... At 

 Tabiky [inland from Cape St. Vincent], I found them in a gallery 

 forest through savannah and dry brush." (Rand, 1935, p. 95.) 



Neither Delacour nor Rand gave the subspecific determination of 

 their specimens. 



Samat's Fat-tailed Lemur 



CHEIROGALEUS MEDIUS SAMATI (Grandidier) 



Chiroffalus Samati Grandidier, Rev. Mag. Zool., ser. 2, vol. 20, p. 49, 1868. 



("Flumen Tsidsibon in littore occidentali Madagascar insulae.") 

 FIG.: Proc. Zool. Soc. London 1872, pi. 70. 



The few known specimens of this lemur come from a limited 

 section of the west coast of Madagascar (Tsidsobon River to Mo- 

 rondava) .
