Head—body mean 75 mm, tail mean 83 mm, hindfoot mean 21 mm, ear mean 10 mm, weight mean 17 g. Male Sinaloan Pocket Mice are slightly larger than females. The northern subspecies rostratus is about the same size as the Desert Pocket Mouse (

). The Sinaloan Pocket Mouse is smooth-haired and small-sized for the genus, with tail longer than head-body length, thinly haired with small crest, and small ears. Relatively soft pelage is usually lacking spines on rump, and if present, these are rather inconspicuous, small, and not asstiff compared with those of coarse-haired species. Pelage of the Sinaloan Pocket Mice is yellowish brown, mixed with light and dark hairs; there is a broad fulvous lateral stripe, under parts are white, and post-auricular patch is only slightly lighter than dorsum. Chromosomal complement either has 2n = 52 and FN = 56 (rostratus) or 2n = 36, FN = 56 (

). Hybridization without introgression between these two species was reported at one locality in agriculturally disturbed habitat. Hybrids had 2n = 49, intermediate between that of the two species, and female hybrids had significantly fewer placental scars, suggesting that hybrids were partially or completely sterile. Compared with the Desert Pocket Mouse,tail of the Sinaloan Pocket Mouse is thinly haired with small crest. In its distribution in the southern Sonoran Desert, the Sinaloan Pocket Mouse is sometimes captured on the same trap lines as three other species of coarse-haired pocket mice. Baileys Pocket Mouse (

), and small woody shrubs on fine alluvial silt nearly devoid of rocks. The Sinaloan Pocket Mouse is restricted to sandy soils in arid coastal plains of Sinaloan thornscrub from the Presa Alvaro Obregon in southern Sonora to Novillero in north-western Nayarit, from barrier islands (including Playas Novillero, Nayarit and Hacienda Island, Sinaloa) at sea level to the lower end of valleys draining the Sierra Madre Occidental at elevations below 90 m. The Sinaloan Pocket Mouse is common on plains below the oak (

near Las Glorias, Sinaloa, in January 2005, 240 live traps yielded only two species of mammals: 57 specimens of the Sinaloan Pocket Mouse and seven specimens of the Southern Grasshopper Mouse (Onychomys torridus), a rodent that preys upon other small rodents and invertebrates.

Diet of the Sinaloan Pocket Mouse consists largely of seeds of shrubs, annuals, and grasses, butit also includes smaller amounts of green vegetation and insects. Food items are collected in external, furlined cheek pouches and transported back to burrows, where they are stored in burrow caches. It does not need to drink water, subsisting entirely on water from its food and water produced as a byproduct of metabolism.
