What terrestrial vertebrate lost its digits but kept their limb [no snakes]?

Question

I know titanosaurs lost their digits in their forelimbs. Due to their massive weight, they pretty much evolved highly specialized columns as forelimbs. 
Emu's also lost their digits. 
Limusaurus, a small theropoda, also lost its digits in its forelimb.

What else?

Damned near all of them. Among terrestrial vertebrates, five digits was the norm. Any limb with fewer than five is the result of the loss of digits. This is especially apparent (and well-studied) in the Ungulates. You can follow the sequence if you place your hand palm down on a flat surface. Raise your palm off the surface and note the order in which the digits leave the table. That mimics the order in which those digits were reduced and then lost entirely.
