GEOGRAPHICAL ZOOLOGY. 



[part IV. 



Species of Mustela have been found in the Pliocene of France 

 and of South America; and Lutra in the Pliocene of North America. 



In the Miocene deposits of Europe several species of Mustela 

 and Ltitra have been found ; with the extinct genera Taxodon, 

 Potamotherium, and Falceomephitis ; as well as Promephitis in 

 Greece. 



In the Upper Miocene of the Siwalik Hills species of Lidra 

 and Mellivora are found, as well as the extinct genera Enhydrion 

 and Ursitaxus. 



The family appears to have been unknown in North Ameri^" 

 during the Miocene period.

The Procyonidse are a small, but very curious and interesting 

 family of bear-like quadrupeds, ranging from British Columbia 

 and Canada on the north, to Paraguay and the limits of the 

 tropical forests on the south. 



The Eacoons, forming the genus Procyon, are common all over 

 North America ; a weU-marked variety or distinct species inha- 

 biting the west coast, and another, most parts of South America. 

 The genus Nasua, or the coatis (5 species ?), extends from Mexico . 

 and Guatemala to Paraguay. The curious arboreal prehensile- 

 tailed kinkagou {Cercohptes candivolvus) is also found in Mexico 

 and Guatemala, and in all the great forests of Peru and North 

 Brazil. Bassaris (2 species), a small weasel-like animal with a 

 banded tail, has been usually classed with the Viverridse or 

 Mustelid^, but is now found to agree closely in all important 

 points of internal structure with this family. It is found in 

 CaUfornia, Texas, and the highlands of Mexico, and belongs 

 therefore as much to the Nearctic as to the Neotropical region. 

 A second species has recently beeji described by Professor Peters
