All Rare mobs that can be found!

Hi guys, I enjoy finding rare mobs but I've noticed that alot of them either don't spawn at all (ie, many of the rares in Felwood, which is very often empty of players and therefore rare mobs should be easier to find), spawn in unusual places (ie, Akubar the Seer (http://www.wowhead.com/npc=8298/akubar-the-seer) in Blasted Lands) or spawn multiples (ie I have seen more than 10 Mirelows at one time in the Wetlands http://www.wowhead.com/npc=14424/mirelow). I've seen a few discussions about rare Cataclysm, Burning Crusade and Northrend mobs, but never seen one for the regular, rare-hunting blokes like me. So here is a list of all the rare mobs that I know exist, any notes I have on their different spawning specifics (if applicable), and I was hoping anyone else who has seen a rare mob not on this list could let rare-hunters like myself know about it.
Thanks!
