PLATE LXXI (continued)<br />

the power possessed by auiitialcules of changing shape and of circulatinij endoplasui. The circulation of living matter in a given<br />

direction by a zooid is a new factor and is to be regarded as a fundamental endowment (the Author).<br />

Figs. 12 and 1.3. Lophomotms striata and Lophovwnas hlattarum with brush-like flagella-fascicles, x 800 (ButschH). Fig. 13<br />

shows beautiful spiral formation.<br />

Fig. 14. Hexamita rostrata with four anterior and two posterior flagella, x 6,50.<br />

Figs. 16 and 16.—Animalcule (Hexamita inflata) dividing by longitudinal fission, x 6.50.<br />

Fio. 17.— Sinular animalcule gyrating upon its attached posterior flagella and producing a beautiful spiral. The spiral is reversed<br />

at intervals, x 1000 (W. S. Kent).<br />

Fig. 18.—Animalcule (Callodictyon triciliatum) enveloping a vegetable fibre, x 400 (Carter).<br />

Fig. 19.—Animalcule (Atractonema teres), pli, Pharynx and vibratile flagellum ; cv, contractile vesicle ; n, nucleus ; a, amylaceous<br />

corpuscles, x 640 (Stein). The direct connection of tlie pharynx with tlie contractile vesicle shown in this figure proclaims the<br />

advent of a stomach and heart in the higher animals, each endowed with independent rhythmic movements (the Author).<br />

Fig. 20.—The same dividing by longitudinal fission.<br />

Fig. 21.—The same with flagellum absent and endojilast enlarged and broken up into germinal elements (g). ph, Pharynx ;<br />

cv, contractile vesicle ; a, amylaceous corpuscle.<br />

Fig. 22.—Animalcule (Phialonema njclostomuni) with spirally ribbed cuticle, x 500 (Stein). Illustrates spiral structures in low<br />

animal forms (the Author).<br />

Fig. 23. —Normal extended animalcule (Eiiglena qnrugyra). aa, Amylaceous corpuscles ; «, nucleus ; cv, contractile vesicle ; e, eyelike<br />

pigment spot (W. S. Kent). Shows oblique spiral markings (in surface of body (the Author).<br />

Fig. 24.—Animalcule (Englena oxyuris), x 200 (Stein). Shows beautiful spiral arrangement well adapted for swimming. Spiral<br />

structures and spiral movements appear very low down in the scale of being (the Author).<br />

Fig. 25.—Spirally twisted non-flagellate animalcule (Phacus longicaudm), x 300 (Stein).
