Fig. 1. The complete living corm, in its natural position, floating with 

 subhorizontal main axis on the level of the sea. A bunch of 

 tentacles issues by the basal opening of the hydrcecial canal. The 

 first and smaller (apical) nectophore is seen from the right side, the 

 second and larger (basal) nectophore from the left side, . . x 3 



Fig. 2. The same corm, in the same natural position, seen from the apical face, x 3 



Figs. 3-7. Different views of the first (proximal or apical) nectophore, . . x 6 



Fig. 3. Apical view of the first nectophore ; the nectosac (w 1 ) appears through 



its dorsal apical facette. (For " cb " read " cl.") 

 Fig. 4. Basal view of the first nectophore ; in the ventral half of the base is visible 



the opening of the hydroecium (ui), including the siphosome (as) ; in the 



dorsal half the ostium of the nectosac (to 1 ). 

 Fig. 5. Lateral view of the first nectophore, from the right side, w 1 , Nectosac ; ui, 



hydroecium ; cs, somatocyst. 

 Fig. 6. Ventral view of the first nectophore, with the somatocyst (cs). 

 Fig. 7. Dorsal view of the first nectophore, with the nectosac {to 1 ). 



Figs. 8-11. Different views of the second (distal or basal) nectophore, . . x 4 



Fig. 8. Ventral view of the second nectophore, with the siphosome (as) enclosed 



in the hydrcecial canal.

 Fig. 10. Lateral view of the basal part of the second nectophore, from the right 



side.
