. Zoology for high schools and colleges. Zoology. Fig. S7.—EpisUjlis fxivicans Ehr., a single, miiny-forlvci co'ony of hell ammalcnles, Blightly magnified. Fig. 28, one of tile animalcules magnified 350 diameters, p, the stem; d, the flat spiral of vibrating cilia at the edge of the disk; ms, the muscle; m to A', the depth of tlie digestive cavity ; m, the mouth ; g, g^^ the throat, or radinieDtary digestive canal; cv, the contractile Tcsicle ; //. the reproductive organ or nucleus.— After Clark. first appearing as a shallow pit, around which arises a semi- circle of vibratile cilia. The mouth and throat form in the new Stentor before any signs of division appear, but in the course of two hours the body splits asunder, and two new in- dividuals appear. Fig. 26 illustrates the mode of self- division seen in Stentor polymorphus Ehretiberg, by Hon. J. D. Cox. The process in this occupied two hours ; at the final stage (Fig. 26, /) the connection between the two ani- malcules parted, " and the two Stentors swam separately.
