Single post in Guide on Albino and Melan Hunting

I'm sorry if this isn't the right spot to ask, but on the guide it mentions trying to hunt for Melans that don't exist yet as an incentive. Is there any way to tell which Melans don't exist? I checked the stats page, and there are less types of Melans (by going to page 14 and seeing what number it ends on) than normal 'mons and shinies, but I can't find a way to tell which Melans are missing. Is there a list somewhere?
