The Longnose Snake grows to a length of 22-30 inches. It has smooth scales, a single anal scale, and at least half the scales on the underside of the tail not divided into rows. The snake's ground color is yellowish or cream with black blotches on the body separated by pink or reddish interspaces.

 Longnose Snakes prefer grassy or brushy, semiarid regions. Open prairies with sandy soils and/or rocky canyons in southwestern counties provide suitable habitat.
