Shell reaching about 60 mm. (2,5 inches) in length, attenuated, thin but strong, imperforate, and with whorls attached.. Whorls 15 and rather strongly convex. Color a pale ivory with a dark brownish band at the periphery and a solid brownish area below the basal ridge. Suture deeply impressed. Aperture subcircular and with a slightly thickened but non-reflected lip. Columella short and arched. Axial sculpture consisting of numerous low, irregular costae with about 22 on the whorl. These costae may appear as low and rather broad flat ridges or may be reduced to very fine threads. Spiral sculpture consisting of numerous irregular ridges which equal in size the finer axial costae. This produces a well defined reticulated pattern. In addition there are much finer spiral threads in between the spiral ridges. Basal area defined by a somewhat thickened ridge and an area of brownish color. Early whorls appear to be slightly angulated. Nuclear whorls not seen. Operculum unknown.

This species ranges from southeastern Florida south through the Caribbean. While generally occurring offshore, it is occasionally washed up on the beaches in Texas. This Amaea reaches a maximum size of approximately 60mm. It is ivory with dark brown bands around the center of the whorls. There are approximately 15 whorls and about 25 costae per whorl.. The thick spiral cords and costae produce a strongly reticulated pattern. The basal disk is dark brown and the columella white.

Amaea mitchelli Dall appears to be quite closely related to the genotype Amaea magnifica Sowerby. We know nothing about this species other than its existence along the Texas coast. It probably has a more extended range, possibly throughout the northern gulf coast area. All specimens seen were collected dead and all are somewhat beach rolled.
