If being of the Genus Tragelaphus is what is required to be considered to be a member of the spiral horns, then the Elands would not be included. But, every time I've seen the spiral list mentioned, the Lord Derby and Livingston(e)/Cape are included. They certainly are the tastiest of the ones listed!!!

I have always heard of it as the spiral horn 9. I'm not a list person and doesn't matter a whit to me.
