Type locality. Norfolk, Virginia. 
The golden mouse is very rare or of local distribution in the parts 
of Georgia and Florida visited by Mr. Brown or myself. I have 
never taken a specimen. Mr. Brown took six at Pinetucky, Georgia, 
and one at New Berlin, Florida. It has been recorded from several 
places in both Georgia and Florida, and Mr. Brownell got it as far 
south as Enterprise, Florida, where judging by the two specimens I 
have seen, it is slightly smaller and of rather a paler yellow color than 
it is farther north, though this southern form seems hardly worthy of 
separation. Mr. J.- Robertson took two examples of P. nuttalii at 
Gainesville, Florida (these were recorded by Mr. Chapman in his 
mammals of Florida), in a cane brake. He showed me the exact 
spot where he got these, and I trapped there for some days, but 
failed to take P. nuttalii. 
P. nuttalii differs from all other North American deer mice in 
the young not having a plumbeous pelage, but being colored exactly 
like the adults. 
Peromyscus niveiventris (Chapman).

Type locality. Oak Lodge, east peninsula, opposite Micco, 
Brevard County, Florida. 
The beautiful little beach mouse is extremely abundant on all the 
beaches of the east peninsula from Palm Beach at least to Mosquito 
Inlet. Just how much farther north it extends, I am unable to say. 
At Point Matanzas I hunted for it in vain, but the beach, for 
walking distance south of the point, was not suited to it. The 
beach was steep and washed away to the dense overhanging growth 
of saw palmetto, leaving no upper beach with its invariable growth 
of sea oats ( Uniola paniculata) , which is the chosen home of P. 
niveiventris. On Anastasia Island there is a different beach mouse, 
while on the beaches north of St. Augustine apparently no beach 
mouse occurs. Mr. Brown spent a week at Burnside Beach and, 
though the beach there, with its fine growth of Umola, was admir¬ 
ably suited to the wants of the little beach mouse, he found no trace 
of it whatsoever.
