JUNE, 1901. MAMMALS FROM N. C., S. C. , GA. AND FLA. ELLIOT. 41 



This beautiful little mouse is a very close ally of P. niveiventris, 

 resembling it so closely that it can only properly be considered 

 as a subspecies. The white of the. under parts extends farther 

 up on the sides, and the back is possibly a little more drab, and 

 that is about all the difference between the two forms. Mr. 

 Surber's notes give the following account of this animal- " This 

 mouse, which is prettier than its near relative P. niveiventris, 

 does not seem to live anywhere but among the scattered tufts of 

 sea oats on the upper beach, and there I was able to trace them 

 to their burrows at the base of a bunch of sea oats or bush, by 

 their little footprints. I saw a great many of their burrows, 

 which were about three-quarters of an inch in diameter, and 

 running back at an angle of about 30 degrees into the sand. The 

 burrows were generally pretty well concealed by the overhanging 

 blades of grass." 



Peromyscus subgriseus. 



Peromyscus subgriseus. (Chapman), Bull. Amer. Mus. Nat. 

 Hist., 1893, p. 340. 

 - Eleven specimens from Gainesville, Florida. 



Of this species Mr. Surber writes: "About two miles south of 

 the city (Gainesville), along the rock road, there is a small, 

 rather rocky hill, cleared of all trees, and grown up in broom 

 grass and rag weed. There appeared to be quite a colony of 

 these interesting little mice in that hill, and though most of the 

 grass and weeds had been burnt away leaving their burrows 

 exposed, they were still holding the ground, and all the speci- 

 mens secured were taken at that place, though I trapped for 

 them in every direction about the city. Apparently they live in 

 colonies and on the higher rocky and sandy ridges. A number 

 of specimens were destroyed by ants, but a small series were 

 saved in good order."

Forty-five examples: 31, Calhoun Falls, South Carolina; 5, 

 Riceboro; 2, St. Mary's, Georgia; 7, Gainesville, Florida. 



There is considerable variation in color among these speci- 

 mens, those from Riceboro being very dark, in fact blackish,
