This test is about 190 microns in diameter and was still attached to the parent from which it was derived by a tough strand of protoplasmic like material.This demonstrates Summer reproduction with a large primary chamber of 55 microns followed by a smaller one of around 30 microns. It is not until the 8th chamber that the size becomes greater than the primary one.It has not yet been cleaned but it emerged from floatation in this condition and the strand broke during mounting.The test was mounted in old canada balsam. The slide is interesting in that it clearly shows the early test development which is often obscured by subsequent growth in adult tests.
