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]

gollark: Anyway. The string metatable is global, and can be set inside the sandbox, yes?
gollark: ```luaif (f1 == p1 and f2 == p2) or (f2 == p1 and f1 == p2) then term.clear() term.setCursorPos(1, 1) print "Accepted. Moving potatOS files. This computer will now boot to CraftOS." for _, filename in pairs(files) do local newpath = ".potatOS-old-" .. filename pcall(fs.delete, newpath) pcall(fs.move, filename, newpath) end print "Press any key to continue." os.pullEvent "key" os.reboot() else```
gollark: It TOTALLY DOESN'T, okay?
gollark: It totally doesn't just enable hidden mode.#
gollark: Yep!
