52 WILD BEASTS OF THE WORLD 



yellow animal is a variety which has become a permanent race, begin- 

 ning as a sport, like the yellow variety of the common Rhesus Monkey. 

 Geoffrey's Marmoset (Midas geoffroyt] of Panama is somewhat like the 

 Pinche', but has merely a white spot on top of the head, not a 

 long bushy crest ; and the Moustached Tamarin (M. mystax) is much 

 like the Black Tamarin, but has white fur on the lips. Then there are 

 two beautiful white species, the Silky and the Black-tailed Marmosets 

 (Hapale chrysoleucus and H, melanura), the latter with a black tail, 

 and the former with a brown one ; these beautiful little things almost 

 rival the Lion Marmoset in beauty, but have not its ornamental 

 mane. 



The most remarkable of all the Marmosets has, however, never been 

 exhibited here, and has, indeed, only been described in 1907. This is 

 the Emperor Marmoset (Midas imperator), in which the male is decorated 

 with a long white moustache, fiercely curled at the ends, which gives 

 him a most absurd appearance, especially as the Marmosets are, except 

 for their pretty little faces, much less human in appearance than any 

 other of the Monkey tribe.
