Rulings
This checks for lands you control with the land type Island or Swamp, not for lands named Island or Swamp. The lands it checks for don't have to be basic lands. For example, if you control Blood Crypt (a nonbasic land with the land types Swamp and Mountain), Drowned Catacomb will enter untapped.

As this is entering, it checks for lands that are already on the battlefield. It won't see lands that are entering at the same time (due to Warp World, for example).
