Head round ; eyes large ; face naked ; ears large, sometimes fringed 

 with hair. Large whiskers are seen on several species, and the neck is 

 sometimes encircled with a ruff. Skull : braincase large ; facial region 

 short ; orbits large ; upper incisors longer than the canines, and all 

 project outward. 



The Marmosets are small delicate creatures, possessing a soft, 

 thick, silky fur, and a long rather bushy tail. In color there is much 

 variety among them, and some have ringed tails. In disposition they 

 are very timid, and while attached to, and familiar with those they are 

 accustomed to meet daily, are shy with strangers, and apt to meet 

 advances with sharp bites. The smooth skull, although the braincase 

 is large, indicates a low order of intelligence. The female produces 

 two or three young at a birth contrary to the general rule, as the 

 females of these Anthropoids have usually but one.
