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

 7 inches in length, exclusive of the tail. The tiny little face is furnished with long 

 brown whiskers, brushed back over the ears ; the general colour of the body being 

 brownish-tawny, but the tail elegantly ringed with black. 3Ir. Bates adds, that 

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

 that wandei-s far from the great river plain. The silky marmoset has, however, 

 also been x-ecorded from Mexico.

Genus Midas. 



The mai-mosets of this gi-oup are at once distinguished from those of the 

 preceding genvis 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 vmaware ; 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 pencilled ears : 

 neither, as we have already mentioned, have thej' ringed tails, although some of 

 the species have the back marked with dark and light ci-oss-bands. 



. The Xegro Tamarix (Midas ursidus). 



One of the liest known of all the species is the common or negro tamarin, which 

 is found in C4uiana and the lower part of the Amazon valley. It belongs to a 

 group in wliich both the forehead and face are hairj-, and the hair of the head
