the division between lower austral and tropical areas, but occurs in 
both areas alike wherever the country is suitable. 
Some species have three subspecies within the limit of the two 
zones, the rice-field mouse, the cotton rat, and the old-field 
mouse being examples; while the large mammals that roam over 
the whole area alike have in every instance a subspecies, the range 
of which is not limited by the tropical zone of south Florida, but 
that occupies the whole of the Florida peninsula and extends north 
certainly to southern Georgia. The two Florida short-tailed shrews 
are as indifferent to local surroundings as are the larger mammals, 
and have about the same range, covering the whole Florida penin¬ 
sula and southeastern Georgia, while the range of the Florida mole 
extends still farther north, certainly to the Savannah River. These 
forms can properly be called “ Floridan ” and probably have their 
origin rather in the peninsulation of their habitat than from the 
effect of the laws of temperature control.
