Fossil Seals. — Remains of living species of seals have been found 

 in Post-tertiary deposits in many parts of Europe and in Algeria, 

 as well as in New Zealand. Fristiplwca occitana is a fossil seal 

 from the Pliocene of Montpellier, wdiile a species of Fhoca is said 

 to have been found in the Miocene deposits of the United States. 



General Femarhs on the Disti^ihution of the Carnivora. 



Terrestrial Coi^nivora. — For the purposes of geographical dis- 

 tribution, the terrestrial and aquatic Carnivora differ too widely 

 to be considered in one view, their areas being limited by barriers 

 of a very different nature. The terrestrial Carnivora form a very 

 extensive and considerably varied group of animals, having, with 

 the doubtful exception of Australia, a world-wide distribution. 

 Yet the range of modification of form is not very great, and the 

 occurrence of three families consisting of but one species each, is 

 an indication of a great amount of recent extinction. One of 

 the most marked features presented by this group is its com- 

 parative scarcity in the Neotropical region, only four families 

 being represented there (not counting the Ursida% which has 

 only one Andean species), and both genera and species are few 

 in number. Even the Procyonidte, which are especially South
