^°°/i. — 7. Horizontal section through the tentacle basis, showing the root of the tentacle and the collo- blast-layer covering both tentacle and the tentacular vessels; further the entodermal liningof the tentacular vessels, having the same character as that of the genital organs. 4o/j. — 8. Part of vertical, nearly median section, parallel to the transversal plane, showing the direct continuation of the suboral cavit\- (f.) into the lumen of the chimney. In the right(subsagittal) genital organ the cavity is seen to be in connection with a branch from thetransverse canal. ^. — 9. Part of vertical median section, parallel to the transversal plane. The tentacle is seen in longitudinal section (combined from 2—3 successive sections). The main transverse canals areseen in connection with the oesophagus; infundibulum rudimentary. A secondary tentacleis seen below the large, normal tentacle. i°/^. Inifol/ K\/?<t/Uiortin ).J^. Ili.MofUfisen. ChruifJiora . Jul). I/■ r.cj. oif

Tt-Mortin.fin.dcl Tfalfieliii Ir-i.sloriitt .\/ft^ Plate VII, Plate Vll. Fig. I. Vertical section, parallel to the sagittal plane, through the apical organ of a grown specimen (Coinp. PI. V. Fig. i6); showing the two excretory canals. The right one was not foundopen in its whole length, undoubtedly on account of a slight curve in its course (due tothe preservation?). The apical organ is seen to be quite rudimentary; no distinct otolithis seen (Comp. Fig. 2), but a pair of otolith cells are seen within the cell mass. — Thethree larger nuclei seen at the upper side of the organ to the left side probably representthe zone of cells forming the cupule, which has disappeared. Cilia were not to be seenhere in the excretory canals. (Not quite reliable in all the histological details, the preser-vation being insufficient for that purpose). 5/i- — 2. Vertical section, in the transversal plane, through the apical organ and the oesophagus of a grown specimen. TJie right side of the upper part
