Type locality. Gainesville, Florida. 
The big-eared Florida deer-mouse is common in all suitable places 
throughout peninsular Florida, though its exact range is unknown. 
It lives only in the higher sandy ridges, where there is plenty of 
black-jack oak and turkey oak, and where the bare white sand is in 
places covered by scattered patches of scrub palmetto. It is the 
characteristic small mammal of such places, commonly known as 
“black-jack ridges,” and I have never found it elsewhere. In the 
neighborhood of Gainesville, the type locality of the species, most 
of the country is under cultivation and spots suitable to its wants 
are not frequent. While there, I trapped with great persistence in 
the three or four most favorable black-jack ridges I could find, but 
took only one example of P. florulanus and this unfortunately not 
fully adult, being of about the age of the type. At Eau Gallie I 
caught a number of specimens, all but five of which were destroyed 
by ants. All the country in the immediate vicinity of the town of 
Eau Gallie is the kind P. floridanus particularly likes, and it is 
apparently common there. 
In 1890 Dr. Merriam described as new under the name Hespe¬ 
romys macropus the fully adult animal from Lake Worth, making 
his comparison with the type of P. floridanus , which is young. 
Mr. Chapman corrects this in his list of the land mammals of Florida, 
but in justice to Dr. Merriam it should be said that the young of 
P. floridanus has a disproportionately small hind foot, and much 
smaller ears than the adult. 
P. floridanus is a very beautiful and distinct species and needs 
comparison with no other member of the genus. I have specimens 
from Gainesville, Citronelle, Eau Gallie, and Enterprise, Florida.
