(Matschek, , 1910.) lay their eggs in batches, of about ten to about a hundred at a time. The eggs when laid do not leave the animal completely, but are cemented together into masses, the so-called egg-sacs, which are carried about by the animal until they hatch. A new batch of eggs is not laid till the previous batch has hatched. In females of Cyclops strenuiis which have not yet laid any eggs, no
