Cochlicella acuta: The pointed helicellid's shell is approximately 10-20 mm high and 4-7 mm wide. It typically has a high spire, giving it an elongated appearance, hence its name. The color of this snail is very variable. It may range from being completely off-white to having regular brown-colored bands and stripes over the entire shell.
C. conoidea: This species is approximately 6-9 mm high and 5-6 mm wide, with 4.5-6 whorls. The shell is either pale grey or tan with brown spots or bands. There is also a brown-colored stripe at the base of the body whorl. The umbilicus (navel) is narrow. The body of the animal is apple yellow to tan with a lighter foot. The ocular (eye-bearing) tentacles are very long and the posterior tip of the foot is pointed.

This coastal species prefers sandy and calcareous soils where it is often found in grassy areas. Under unfavorable environmental conditions, this species will aestivate on vertical structures (e.g., posts, walls). This snail can lay on average 36 eggs per clutch. Cochlicella acuta has been reported as a pest of fodder crops (i.e. alfalfa, clover, lupine).
