If you were an animal in another life and were reincarnated as a human in this life, then proceed to eat a member of your former species, then you have engaged in Transmigratory Cannibalism.
For example, I was a stingray in a former life. I recently went fishing, caught a stingray, grilled ate ate it. While consuming the stingray I had the passing thought, "This could be my cousin!", which could be called Extended Familial Transmigratory Cannibalism.
