What are all the parallels races from warhammer to warhammer 40k ?

Sadly some of them have been retconned, in the early days of Warhammer 40K there were IG and Chaos IG Beastmen, Squats (Space Dwarves), Zoats, Slann and a few other minor oddities. Space Marines AND Imperial Guard both got bikes, jetbikes, Rhinos and Land Raiders. Ogres are still there as Ogryns.
