GENERAL RESULTS 
DEDUCKD FROM 
A COMPARISON OF THE SPECIES EXAMINED IN COMPILING 
THE FOREGOING TABLES. 
PLIOCENE PERIOD. 
Italy, Sicily, the Morea, Perpignan, and the English Crag. The fossils 
of Perpignan and the Morea are, with the exception of three or four 
species, the same as those of Italy.

The number of living analogues is 350, which is in the proportion of 
49 in 100. 
MIOCENE PERIOD. 
Bordeaux, Dax, Touraine, Turin, Baden, Vienna, Moravia, Hungary, 
Cracovia, Volhynia, Podolia, Transylvania, Angers, and Roncaf. 
The species of Moravia, Hungary, Cracovia, Volhynia, Podolia, and 
Transylvania, are the same, with a very few exceptions, as those of 
Vienna and Baden. 
* The statement that there are only 4 species common to Italy and the Crag, 
may seem inconsistent with the fact that 18 are common to those places and to 
Sicily ; but the reader will understand that there are only 4 species which are 
common to Italy and the Crag, and which are not also common to some other 
Pliocene locality. The same remark is applicable to similar statements in the 
sequel. 
f Ronca may very probably belong to the Eocene epoch ; but in this, as in re- 
spect to a few other localities mentioned in the tables, the number of analogues -is 
too small to lead to certain conclusions.
