Indeed Marisa.
Despite both Marisa and 'ramshorn snails' having a shell shape of the type referred to as "Planorboid" (or 'Ramshorn'), they belong to two separate (not even closely related) families: Ampullariidae, and Planorbidae.
One immediate and easy to see difference between Marisa (Ampullariidae) and true Ramshorns (Planorbidae) is that Marisa has an operculum (trapdoor), just like and apple snail. Planorbid ramshorn do not have an operculum. Also, Marisa are separate sexes (male and female individual snails, and will copulate). Planorbid ramhorns are hermaphroditic (both sexes within invidual snails), but they can outcross.
