Descriptive notes. Head—body 82-93 mm, tail 40-60 mm, ear 12-17 mm, hindfoot 15-19 mm. No specific data are available for body weight. The Oldfield Deermouse is small, with almost white to pale cinnamon or buffy dorsum, depending on substrate color. Venteris white. Tail is bicolored and shorter than head-body length. It is morphologically similar to the North American Deermouse (P. maniculatus), but its skull is much smaller.
Habitat. Normally old fields, abandoned fields, and beach habitats. The Oldfield Deermouse preferred areas included cactus patches, sandy fields with sparse grass cover, cotton and corn fields, fence rows, and open timber tracts. Sandy soils are preferred for digging burrows.
Food and Feeding. The Oldfield Deermouse eats variety of seeds, blackberries, and wild peas.
Breeding. No information.
Activity patterns. The Oldfield Deermouse is presumably nocturnal.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red List. Seven coastal forms are of conservation concern: trissyllepsis is Critically Endangered; allophrys, ammobates, peninsularis, and phasma are Endangered; and leucocephalus and nwverventris are Near Threatened. All these subspecies have restricted distributions and are threatened by habitat loss and degradation.
