In the preceding lists only those faunas have been given which 

 are abundantly represented in species and individuals, and which 

 may, therefore, be considered characteristic. Of all the faunas cited, 

 that from the waterlimes of Oesel, while not containing the largest 

 number of species, is yet the one which is preeminently representa- 

 tive. The eurypterids undoubtedly lived and died in the muds now 

 forming the waterlimes, the remains which are found there having 

 suffered practically no transportation, as we may judge from the 

 perfection of preservation and the entirety of individuals. The speci- 

 mens of Eurypterus fischeri occur in greater numbers and in a more 

 perfect state than do those of any other known species, and the exo- 

 skeletons are not only not compressed, but they even show the origi-
