 a peculiarity of the species. {Anderson.) 



III. RUFOUS STUMP-TAILED MACAQUE. MACACUS RUFESCENS. 



Macacus rufescens^ Anderson, P. Z. S., 1872, p. 204 (Juv.) ; 

 id., Zool. Exped. Yun-nan, p. 79 (1878); Scl., P. Z. S., 

 1872, p. 495, pi. xxiv. ; 1873, p. 194. 



Macacus arctoides^ Schl, Mus. Pays-Bas, vii., p. 116 (1876; 

 part). 



Characters. — Very nearly related to M. arctoides^ of which it 

 is perhaps only a southern race. Face red, more brilliant 

 round the orbits ; nose and lips brownish ; tail stumpy, thinly 

 haired. Fur rather brilliant' brick-red, especially on the 

 cheeks, flanks, and outside of the limbs. This animal is 

 known, however, only from young specimens.
