Shell description

Amphicyclotulus dominicensis has spiral cords which are clearly visible and raised.[3]

There are only two species in the genus Amphicyclotulus in Dominica.[3] The other species is Amphicyclotulus amethystinus, which has either no spiral threads or ones that are only weakly present.[3]

Amphicyclotulus dominicensis is smaller than the Amphicyclotulus amethystinus.[3] Amphicyclotulus dominicensis is more coarsely sculptured and has a higher spire.[3] It has been found on the leeward and windward sides of the island of Dominica, at low elevations only.[3]
