Map illustrating approximate distribution of Wood Rats (Neotoma) in eastern United States. 
Neotoma pennsylvanica* STONE. (Proc. Acad. Nat. Sci. Phila., 1893, p. 16.) Type 
locality — South Mountain, Cumberland Co., Pennsylvania. Total length 
about 16.50 in. (418 mm.); ears large; color dull brownish plumbeous, above 
mixed with black hairs; feet and under parts white; tail bicolor, above brown, 
under surface white; first upper molar with anterior inner notch or angle, deep, 
extending more than half way across the lobe. 
Neotoma floridana (ORD). (Bull. Soc. Philom. Paris, 1818, p. 181.) Type locality — 
St. John’s River, Florida. Smaller than pennsylvanica and more plumbeous, 
tail less thickly haired; skull slighter; first upper molar with anterior inner 
notch or angle, shallow, extending less than half way across the lobe. 
Neotoma f. attwateri (MEARNS). (Proc. U.S. Nat. Mus., XIX, 1897, p. 721.) Type 
locality — Lacey’s Ranch, Turtle Creek, Kerr Co., Texas. Similar to floridana 
but pelage longer and grayer in summer; tail less than 674 in. (175 mm.). 
* Neotoma magister BarrD, described from lower jaws found in Pleistocene cave 
deposits near Carlisle, Pennsylvania (Baird, Mammals N. Amer., 1857, p. 498), is
