tion is to be found in the presence of darker and lighter rings on the tail. The 

 general color of the body is a tawny or ferruginous brown, more or less varied with 

 black and red on the back ; the neck, under parts, and inner surfaces of the limbs- 

 being yellowish, and the hands and feet yellowish brown. 



Three specimens of the pigmy marmoset were obtained by Mr. Bates on the 

 upper Amazon, at San Paulo, near Ega. They are described as measuring only 

 seven inches in length, exclusive of the tail. The tiny little face is furnished 

 with long brown whiskers, brushed back over the ears ; the general color of the 

 body being brownish tawny, but the tail elegantly ringed with black. Mr. Bates 

 adds that this marmoset ranges as far north as Mexico, and is the only Amazonian 

 primate that wanders far from the great river plain. The silky marmoset has. 

 however, also been recorded from Mexico.

THE IvONG-TUSKED MARMOSETS, OR TAMARINS 

 Genus Midas 



The marmosets of this group are at once distinguished from those of the- 

 preceding genus by the circumstance that the tusks, or canine teeth, of the lower 

 jaw are considerably longer than the front, or incisor teeth ; so that the whole 

 series of lower teeth does not present the even and regular height characteristic of 

 the short-tusked marmosets. Why Buffon applied the name tamarin to one member 

 of this group, we are unaware ; but it has been subsequently very generally adopted 

 for two of the species, and is a short and convenient name by which to designate 

 the entire genus. None of the tamarins have penciled ears ; neither, as we have 

 already mentioned, have they ringed tails, although some of the species have the 

 back marked with dark and light cross-bands.
