Which of the following group is known as wheel Animalcules?

In a common group of rotifers (the Bdelloida) this apparatus is in the form of two flat discs which give the appearance of revolving wheels when the cilia are in motion. These were the first rotifers to be described, and they give the name of ‘ Wheel Animalcules’ to the group.

What were animalcules later discovered to be?
