Tentacle and tentacle basis, seen from the apical side, of a young (regenerated) specimen. The small genital organs (only the subtentacular pair drawn) are seen to develop at the endof small branches from the tranverse canal, ^s/j. (Comp. Fig. 12). — II. The basal surface of a grown .specimen. The furrow (suboral cavity) is opened so as to show the large stomodseal folds, in the middle of which is seen the narrow opening of the oeso-phagus (in the figure designated o). The hole (o. f.) at each end of the furrow represents theopening from the furrow into the lumen of the chimneys, ^i • (Comp. Fig. 5). — 12. Tentacle and tentacle basis of a grown specimen, seen from the outer side. The small finger-shaped body at the base of the tentacle probably represents a secondary (abnormal)tentacle. (Comp. Fig. 10). The two large bodies lying over the tentacle basis are the twosubtentacular genital organs, -s/j. llHfoll /.\/>lull/il>llfll \.J. TIt.MorU-ii.scii. Clprio/iJuira . lah.lll.

IjairielUi IrLfLoniii .l//7,sy/. Plate IV. Plate IV. Fig. I. Vertical section, along the transversal plane, through a grown specimen. /^ The section isnot median. The figure shows the four genital organs of the same side, the two medianones showing the arrangement of the ovary and testis, the ovary medially, the testis later-ally placed. Below the outer genital organ is seen the tentacle-basis. The strongly foldedlower side of the section represents the stomodseal folds. On the left side is seen the con-nection between the chimney cavity and the suboral cavity. The clear spaces below thegenital organs and especially in the outer part to the right are sections through the branchingperipheral canals. — 2—4. Successive horizontal sections through the upper (apical) part of a grown specimen. 7/j.In fig. 2 the section goes through the apical organ, in fig. 3 through the transverse main(perradial) canal, in fig. 4 through the upper part of the oesophagus.
