1. Eucirripathes contorta v. Pesch. Vertical transversal section through an oral cone with three oral 
apertures, three actinopharynges, three sets of mesenteries; i and 3 are young polyps, 2 is the 
original polyp. In all three polyps the mouth itself is not attained, but the actinopharynx; 39 x. 
2. Eucirripathes contorta v. Pesch. Polyps 1 and 2 out of fig. 1, but more towards the polypar limit; 
the branched mesenterial filament (m. f. 3) appertains to polyp 3; 39 X- 
3. Eucirripathes contorta v. Pesch. Horizontal section through a primary transversal mesentery with 
unilateral mesogloeal lamellae; 16 r X- 
4. Eucirripathes contorta v. Pesch. Vertical transversal section through a polyp near the polypar 
periphery; 39 x. 
5. Eucirripathes contorta v. Pesch. Horizontal section through the upper part of the oral cone, with 
ten mesenteries; 39 X. 
6. Eucirripathes contorta v. Pesch. Interzooidal septum (vertical cross-section through a polyp); 39 x. 
7. Eucirripathes contorta v. Pesch. Somewhat oblique horizontal section through the oral cone and 
the actinopharynx; the right fialf is omitted; in the upper part of the figure the cone is 
attained at a lower level than in the lower part; 39 X- 
8. Eucirripathes musculosa v. Pesch. Tangential longitudinal section through the oral cone; 39 X- 
9. Eucirripathes musculosa v. Pesch. Vertical transversal section through oral cone and bodywall; 39 x. 
10—14. Eucirripathes anguina (Dana). Succeeding vertical transversal sections through a polyp; part 
of the oral cone, the actinopharynx and the sagittal tentacles; 39 X. 
15. Eucirripathes anguina (Dana). Horizontal section through the actinopharynx; 39 x. 
16. Eucirripathes anguina (Dana). Horizontal section through a primary transversal mesentery with. 
ovaria and mesenterial filaments; 39 x. 
17. Eucirripathes nana v. Pesch. Longitudinal section through actinopharynx and oral cone (vertical 
cross-section through a polyp); 39 X- 
lb. Elicit 1 ipathes nana v. Pesch. transversal section through the lower part of the actinopharyngeal 
wall (vertical transversal section through a polyp); 39 x. 
l 9 - Eucirripathes nana \. Pesch. Vertical transversal section through a polyp with a fusion between 
the sheath of a spine and a mesentery; 39 X- 
20. Eucirripathes nana v. Pesch. Vertical transversal section through a polyp, at the limit of the 
oral cone; 39 X. . 
21. Eucirripathes nana v. Pesch. Vertical transversal section through the bodywall, the connecting 
septum, the axis-epithelium and a fusion of the sheath of a spine with the bodywall. The 
entoderm and the ectoderm are only partly figured; 161 X. 
22. Eucirripathes spiralis (Blainv.) v. P. var. aphanipathoid.es . Oblique section through the oral cone, 
the actinopharynx and the epithelial sheath of a spine; 39 X. 
23. Eucirripathes anguina (Dana). Horizontal section through a secondary mesentery with unilateral 
mesogloeal lamellae; 161 X- 
24. Eucirripathes contorta v. Pesch. Horizontal section through the mesogloea of four mesenteries 
in the oral cone; 161 X- 
25. Eucirripathes Rumplui v. Pesch. Transversal section through a tentacle with the nematocyst- 
batteries left blank; 69.5 X. 
26. Eucirripathes translucens v. Pesch. Fusion of the bodywall and the epithelial sheath of a spine; 39 X- 
In all the figures of PI. V (except fig. 25) the mesogloea is black, the entoderm and the 
ectoderm are gray, the actinopharyngeal ectoderm is gray and hatched, the pigment is dotted. 
The arabic numbers of the figures correspond with the roman ciphres on the plate.
