think I have never been able to save more than three out of every 
five caught. 
B. floridana is larger than B. paw a , with which I believe it 
intergrades, has a longer tail, and is grayer in color with a decided 
“pepper and salt” appearance, the molar teeth are different and 
the skull longer. The largest individual I ever caught is No. 3,444 
from Oak Lodge. It measures, total length, 104; tail vertebrae, 
26; hind foot, 12. 
I have specimens from St. Mary’s, Georgia, and Carterville, Point 
Matanzas, Gainesville, and Oak Lodge, Florida. At the latter 
place I collected a series of eighteen individuals.

Type locality. Gainesville, Florida. 
The Florida mole is distributed over the whole of eastern 
Georgia and Florida south to Lake Worth and Tampa Bay (except 
Anastasia Island, where a peculiar insular form occurs) . Specimens 
from Gainesville, however, do not represent the extreme of the 
form, which the “ Scalops pawns ” Rhoads from Tarpon Springs 
does. The subspecies must, however, be known as S. australis, as 
the differences between S. australis and S. aquaticus typicus are 
much greater than those between S. australis and S. pawus. 
Scalops australis does not vary to any considerable extent in the 
region between the Savannah River and Gainesville, in the charac¬ 
ters that separate it from true S. aquaticus ; namely, smaller size, 
short tail, relatively larger hind foot, smaller, lighter skull, 
smaller teeth, and lower and very much more slender coronoid 
process. On the peninsula farther south than Gainesville, the mole 
becomes still smaller with even a lighter skull. 1 
The Florida mole is very abundant and lives both in hummocks 
and piny woods, and the ridges—the roofs of its underground run- 
iNone of the peculiar characters claimed for “ S. parvus ” by its author, Mr. S. N. 
Rhoads, are more than individual variations, as is shown by a rather younger topotype 
and the type of S. parvus, now both before me. The type is a rather peculiar and 
apparently dwarfed individual, perhaps due to its having been kept alive in confine¬ 
ment. (See True’s Monograph of the North American moles.)
