We choose as an example thetolerably complicated life-history of the fluke, Distoma hepaticum(Fig. 119), which is parasitic in the liver of the sheep, causing the sheep rot. The eggs of the fluke leave the liver of the host by thebile ducts, pass into the intestine, and are ejected with the excrement.They only develop when they meet with water. In this case theredevelops in the egg shell (A) a ciliated embryo, which leaves the Ill PL AT ODES— LIFE-HISTORY OF TREM

If hosts and cysts are eaten by an actinian the metamorphosed ciliates are liberated and these take up life again in the gastral cavity of the coelenterate. Of the endoparasitic forms the Pycnothricidae (Xicollelidae of Chatton and Perard) are noteworthy because of the varying posi- tions of the mouth, which is connected with an elongated furrow.
