Professor Verrill records in »Proceedings of United States National Museum« for 1879, p. 199, an Alcyonarian, to
which he has given the name of Alcyonium multiflorum. and that would seem to approximate Duva rosea rather closely; but
to judge from his very brief description, unaccompanied too, as it is, by figures, we are disposed to regard the animal as a
form specifically distinct from Duva rosea, though it certainly will have to be referred to the genus Duva, since, for divers
reasons, it does not admit of being classed under the genus Alcyonium.
Duva pellucid a, n. s p.
Tab. Ill, figs, i—II.
Specific Character.
The zoanthodeme tree-like. The trunk 14—15 mm. high and 4 mm. broad at the base, branched, and with the
basal part dilated. At the extremity of each branch, a group of from 5 to 7 short, bell-shaped polyps, having on the anterior
part of the body 8 series of elongate, thorny — part straight, part curved — spindleshaped spicules, — produced on to the
tentacles. The branches and the upper half of the trunk without calcareous deposit. The basal part and the lowermost part of
the trunk calcareous. The spicules occur here, as a rule, as simple double stars. The trunk, the branches, and the polyps
hyaline, pellucid, and over the whole surface densely beset with nematocysts.
Duva puler a, n. s p.
Tab. Ill, figs. 12—24.
Specific Character.
The zoanthodeme greatly branching. The trunk 12 mm. high, and 5 mm. broad at the base. The branches as a rule
ramifying, and each branch or branchlet having at the extremity from 3 to 5 polyps. The polyps exceedingly ventricose,
with retractile tentacles. The whole body of the polyps beset with thorny spicules, part spindleshaped, part clubshaped. The
tentacles furnished with a series of transversely placed flat spicules. The lower half and basal part of the trunk abundantly
provided with simple and complex double stars; the upper half, as also the branches, without spicules. Colour a milky white.
