BANGS: LAND MAMMALS OF FLORIDA AND GEORGIA. 177 
Geomys is concerned. In Florida and Georgia one seldom finds 
Geomys hills anywhere but on the highest and dryest land, although 
once at Carterville, while walking along the edge of the marsh, I 
found three or four fresh salamander hills thrown up in the damp, 
black earth; on digging down through one, I came to the runway 
only a few inches below ground and half full of water. I placed a 
trap in the run and coming back in a short time had the salamander, 
a solitary old male living at least two miles from the nearest colony. 
G. floridanus can be distinguished from G. tuza by its larger size, 
bigger hands and feet, duller coloring, and the presence of a white 
spot under the chin. While the cranial characters that separate the 
two species are well marked, G. floridanus having much larger audital 
bullae, wider ascending branches of maxilla, and narrower nasals, 
the old males of G. floridanus have a much greater tendency to 
develop a sagittal crest than have the old males of G. tuza. l 
In February, 1897, I took thirty-one specimens of G. floridanus 
at Carterville, fourteen miles south of St. Augustine, and in March 
of the same year eleven at Eau Gallie. In April, 1896, I caught 
three at Rose Bluff on the Florida side of the St. Mary’s River, 
and Mr. Brown took a series of 101 at New Berlin, Florida, on the 
St. John’s River. Those from the last two places are a little 
brighter in color than the Carterville or Eau Gallie specimens, but 
in proportions and cranial characters show no approach to G. tuza.

Geomys floridanus austrinus subsp. nov. 
Type from B.elleair, Hillsboro County, Florida, $ adult, No. 
6,983, collection of E. A. and O. Bangs. Collected, Aug. 3, 1897, by 
W. S. Dickinson. 
General characters. Size and proportions of G. floridanus 
typicus. Color above much paler and more tawny; much more 
white on under parts. Skull slightly different. 
Color. Upper parts: pale cinnamon and tawny shading on lower 
sides to ocliraceous buff. In very fresh pelage sometimes slightly 
darker and somewhat shaded with drab. No darker dorsal stripe, 
though sometimes this is faintly indicated in the fresh pelage. 
1 Dr. Merriam probably did not have any very old male skulls of G. floridanus as be 
does not mention the sagittal crest of this form. In the large number of skulls of G. 
tuza that I have examined in a few of the oldest males the lateral crests have come 
entirely together so as to form a distinct sagittal crest. This condition is usual in the 
old males of G. floridanus.
