Help identifying acan

[migs]

So I am starting my collection of scolys, micromussa, and acans... I picked up these two... The one on the right looks like echinata but have no clue about the one on the right... Very flat and bigger than my other acan lords. Any ideas?

Ok, so that was a bad pic... take 2.
