One other name I've heard used, pretty much ever since the dos days when the 16 character fixed sized keyboard buffer was the first instance of such a structure I'd seen, was a 'ring buffer'. Data.RingBuffer perhaps? I agree that Data.Ring is a terrible name, partially because I already have a Data.Ring in the monoids package!

Is Necklace a known name for this data structure? ÂIf not Ring, I was
thinking Circular might be an appropriate name.

I'm not sure if there's a canonical name, except perhaps "circular queue". Necklace is cute, though Circular or CircleQueue might be better. I'd also advise strongly against using Ring in order to avoid confusing nomenclature. (Loop should be avoided for similar reasons.)
When reading "Ring" first time in the e-mail subject, I also thought it would be about the algebraic structure with that name.

CircularList seems fine to me. Necklace is nice but might be missed when someone searches for that data structure on Hackage.
