yet be found a common species, I feel perfectly safe, for by far 

 the greater part of the island is just suited to its habitat, being 

 an endless growth of scrub, and high and dry." At Enterprise 

 he found this species " in the flat woods scrub. In some places 

 in those woods the scrub oaks and saw palmettos grow rather 

 sparingly, leaving the bare white sand showing in large patches, 

 and here is where I secured all my specimens. In the flat woods, 

 one-quarter of a mile west of Micco, I secured quite a little series 

 of this beautiful mouse in identically the same character of 

 surroundings as at Enterprise, and we must conclude it is as 

 plentiful in the flat woods, when not too thickly overgrown with 

 scrub, as on the sand hills. At Micco I took one in the fresh water 

 marsh. On Anastasia Island all the specimens of this mouse 

 were taken on top of the sand ridge next the beach." No 

 examples were procured at Gainesville, and the country about 

 Crystal River was not suitable for the animal, but at Citronelle 

 and Tarpon Springs it was favorable. At the latter place many 

 burrows were found under clumps of dead beanstalks and grass, 

 "about 2 to 2^ inches in diameter, and 6 inches deep, descend- 

 ing perpendicularly in the sandy soil. No effort was made to 

 conceal the entrance. I could not find them in any other place, 

 though sand hills and ridges suitable for their abode were 

 common enough."

Four specimens: 2, Oak Lodge; 2, E. Penn opposite Oak 

 Lodge, Florida. 



Of this species Mr. Surber says, "I took over 30 specimens 

 of the beach mouse on the East Peninsula just south of Oak 

 Lodge, but the ants ruined all but four. They did not appear to 

 be very numerous as I had about sixty traps out and should have 

 caught over a hundred in the same length of time if they had 

 been abundant. I found them nowhere but among the sea oats 

 on the beach."
