the ground and are made of leaves and dry grass. Sometimes the en- 

 trance to the nest is closed when the animal is in the burrow. 



During the colder months of the year, woodland jumping mice 

 hibernate, and their life processes are reduced to a mininum. In the 

 autumn they eat heavily and accumulate large stores of fat on the body 

 to carry them over the long period of hibernation. Their hibernation, 

 deep and prolonged, is usually half of the year. 



Hamilton (1941, pp. 260-261) lists the food of the woodland jump- 

 ing mouse as insect larvae (particularly lepidopterous and dipterous 

 forms), spiders, small soil worms, centipedes, various small inverte- 

 brates, small seeds, tiny nuts, small green leaves, blueberries, rasp- 

 berries, and fragments of Asplenium fronds. 



This species normally raises but one litter a year. The gestation 

 period is between 20 and 23 days, and from two to six young, possibly 

 eight, comprise a litter ; the most frequent number appears to be five. 



Specimens examined. — Allegany County: Dans Mountain, 2. Garrett 

 County: Finzel, 1; Grantsville, 5 miles SE (Savage River State For- 

 est), 8 (Coll. U. Mich.) ; Muddy Greek Falls, 3 (Coll. U. Md.) ; Swal- 

 low Falls State Forest (along Muddy Creek) , 1. 



Remarks. — Although Preble (1899, p. 35) noted that the specimen 

 he collected at Finzel showed no approach to N. i. roanensis (type 

 locality: Eoan Mountain, N.C.), it is my opinion that this specimen 

 and one from Swallow Falls State Forest and eight from 5 miles SE 

 of Grantsville show traits that are characteristic of roanensis. They 

 are smaller in size and darker in coloration than typical insignis, and 

 they appear to represent intergrades with roanensis. However, they 

 are closer to insignis than roanensis in these characters and are herein 

 assigned to the former subspecies.

Type locality. — En^neer Cantonment, about 12 miles southeast of the present 

 town of Blair, Washington County, Xebr., on the west bank of the Missouri 

 River. 



General distriMtion. — Distributed primarily west of Mississippi River, from 

 Alaska to Central America, with the center of population in the Great Plains 

 of the United States. The si)ecies has recently been reported from a number of 

 Eastern States, and apparently has been expanding its range eastward. Some of 

 the eastern populations, however, may be derived from animals that escape from 

 captivity, particularly those populations in Southern States.
