This list of localities is not very 

 imposing, considering the vast span of 

 time which it includes, and even so it 

 is somewhat misleading, as several of 

 the localities have furnished only one 

 or two specimens and only four or five 

 have furnished anything like a fauna in any true sense of the word.
