About Atrimitra idae (Melvill, 1893)
This species, Atrimitra idae, has a strong, heavy shell. Adult shells range in length from 20 to 60 mm. The columella of the shell has three distinct folds. The shell itself is pinkish-tan, but living individuals have a thick black periostracum covering the shell. The soft body of the animal is entirely pure white, except for its black eye spots. Atrimitra idae, a type of miter, is distributed from Northern California, United States, south to Baja California, Mexico.
