138 EXTINCT AND VANISHING MAMMALS 



The same author describes the native method of capturing these 

 lemurs by means of snares arranged on "a line of poles set up on 

 forked sticks across a long, narrow clearing, forming a bridge from 

 the trees on one side of the clearing to those on the other." 



[In view of the still existing uncertainty concerning the taxonomic 

 status of Prosimia flavijrons J. E. Gray, the exact type locality of 

 which is unknown, it seems hardly worth while to give a separate 

 account of it here. Schwarz (1931, p. 412) , after provisionally con- 

 sidering it a synonym of L. m. collaris, proposes later (1936, p. 24) 

 to recognize it as a distinct subspecies of L. macaco and assigns 

 to it a range at Maromandia, northwestern Madagascar. On the 

 other hand, G. M. Allen (1939, p. 127) regards it as "probably a 

 synonym of Lemur macaco collaris" whose range lies at approxi- 

 mately the opposite end of Madagascar from Maromandia.] 



Red-fronted Lemur 



LEMUR MACACO RUFUS Audebert 



Lemur Rujus Audebert, Hist. Nat. Singes et Makis; Makis, p. 12, 1800. (Type 



locality not stated = Madagascar.) 

 SYNONYM: Lemur rufifrons Bennett (1833). 

 FIGS.: Audebert, 1800, Makis, pi. 2; Milne Edwards and Grandidier, 1890, 



pis. 138, 139, 145. 



This is apparently one of the more common of the Madagascar 

 lemurs. 



Female (type of rujus) : similar in size to L. mongoz, but differs 

 in shorter ears, shorter hairs on tail, and rufous pelage; snout, and a 

 line from forehead to crown, black; crown, temples, cheeks, and 

 throat dirty white; body yellowish rufous; tail brown at the tip 

 (Audebert, 1800, Makis, p. 12) . Male (type of "rufifrons") : back 

 grizzly; tail darker; under parts, haunches, and limbs mixed with 

 rufous; forehead and cheek-tufts rufous; a nearly complete circle 

 of white about the eye; nose, and line through middle of forehead, 

 black (Bennett, 1833, p. 106) . The male differs from males of other 

 subspecies of L. julvus in having a rusty-red forehead (Schwarz, 

 1931, p. 410). This form is very variable in coloration. 



Schwarz (1931, pp. 413-414) describes its occurrence as follows: 



The range of L. f. rujus includes the greater part of Madagascar, all the 

 central plateau, and the west coast. ... It would appear that, except the 

 north and a fairly narrow strip on the east coast, the whole mainland of 

 Madagascar is inhabited by this race. 



As a matter of fact the majority of the individuals found north of the 

 Betsiboka River are black-headed and much like the black-headed phase of 

 L. /. albijrons; but there can be no doubt that a mixed population is found 

 in a considerable part of the north. At present I am not prepared to say
