General remarks. Cumberland Island is the only one of the 
Sea Islands on which a Geomys occurs. In the spring of 1896 I 
heard that salamanders were found on Cumberland Island and, 
having secured permission to trap there, went over and caught 
thirteen salamanders, April 17-18. The colony was centered in 
some old fields on the Stafford Place, but the hills straggled off 
through the pine woods for miles. Mr. Brown, when he visited the 
island a year afterwards, did most of his trapping at the northern 
end and took there thirteen additional specimens of G. cumber¬ 
landius . 
Average flesh measurements of fully adult specimens of Geomys 
from Georgia and Florida.
