The small-tailed, furry, brownish-gray mammal was first described in the scientific literature in 1839, from a specimen collected near the mouth of the Columbia River.

At birth, they weigh 1.6 g (1⁄16 oz), are naked, pink, unable to open their eyes, and the ear flaps completely cover the ear openings. Although not always common throughout their range, there are no major concerns for their survival as a species.

The type specimen was an older male collected November 2, 1836 near the mouth of the Columbia River in Oregon. The specimen had been submitted to Bachman for review by John Kirk Townsend. Subsequent authorities state that it was collected at Astoria, Oregon, which is at the mouth of the Columbia... Wikipedia →
