GENUS HAPTOPHRYA. 569 This form, selected by Stein as the type of his new genus Haptophrya {Disco-phrya), is identical with the Opalina planariaruvi of Siebold and the Opalina poly-morpha of Max Schultze, In the original illustrations of this species given bythe last-named authority,* and reproduced in the accompanying woodcut, the aceta-buliform organ, as delineated most distinctly at Fig. 2, forms a complete circle andis not bordered with cilia of conspicuously larger size than those which clothe thegeneral cuticular surface. The body is also seen, from Figs, i and 2, to exhibit inits fully developed state a remarkable disparity of size in different regions, thepart succeeding the anterior disc-like organ being much strangulated and endoplast is represented as a small, granular, ovate body, located close to theposterior Hapioi>hrya planariariim, Siebold sp.—i and 2.

Body elongate, cylindro-conlcal or wedge-shaped, tapering from thefront backwards, a little over twice as long as broad ; the anterior extremitydepressed, about twice the breadth of the posterior region, provided with acircular adhesive disc; the ectoplasmic layer or cuticle longitudinallystriate, but non-contractile, thickly clothed with fine, short, vibratile cilia,which are disposed in close-set longitudinal rows; cilia of somewhat largersize bordering the inner margin of the adhesiv
