Sympodium norvegicum, n. sp.
Tab. VII.
Specific Character.
The zoanthodeme without any trunk, incumbent. The basal part, abounding in spicules, consists of an expanded,
firm membrane, which, in the places enclosed by the groups of polyps, is comparatively thick. The polyps, about 4 mm.
long, cylindrical, occur in groups, are completely retractile and slightly grooved longitudinally. The anterior part of their
body, with the tentacles and pinnules, abounds in spicules, having the form of spindles, clubs, crosses (Vierling), and plates;
the posterior part of the body without spicules. The polyp-cells project a little up above the basal part, are conical, wholly
conceal the retracted polyp, and abound in spicules, the great majority of which occur as double spheres. Along the oesophagus
4 series of spicules, 2 on the ventral and 2 on the dorsal side.
Haimeia hyalina, n. s p.
Tab. VIII, figs. 1—9.
Specific Character.
The coralloid part of the body soft, flexible, 3 mm. long and 0.759 mm. broad, a trifle ventricose immediately above
the flat, diskoid basal part, and everywhere furnished — with exceedingly thorny somewhat scattered spicules, having the form
of crosses, clubs, and spindles, — as also though sparingly with nematocysts.
The mouth oblong, bilabiate. Eight cylindric tentacles, 2 mm. long, abounding in spicules and nematocysts, and
furnished with long pinnules, at the base of which occur two thorny spicules, and, on their aboral side, extending transversely
towards the adoral, riband-shaped prominences, densely beset with ovoid nematocysts. The whole of the coral hyaline
and translucent.
Briareum Friele i, n. sp.
Tab. VIII, figs. 10—26.
Specific Character.
The trunk abounding in branches and ramifications. The branches knotty. Both the branches and the knots have
