Art. XXXII.—Contributions to the Cœlenterate Fauna of New Zealand.

[Read before the Otago Institute, 14th October, 1879.]

Siphonophora.

Diphyes appendiculata, Eschsch. Acal., p. 138, pl. 17, f. 7; Lesson, Acalèphes, p. 447.

Found occasionally on the coast near Dunedin.

Sarcoconus imbricatus, Quoy and Gaimard, Voy. Astrolabe, Zoologie, IV., p. 71, pl. 3, f. 13 and 15; Lesson, Acalèphes, p. 479.

Physophora australis, Quoy and Gaimard, Voy. Astrolabe, Zoologie, IV., p. 57, pl. 1, f. 19–21; Lesson, Acalèphes, p. 507.

Not uncommon on the coast near Dunedin.

Physalia megalista, Peron et Lesueur, Voy., 2nd ed., pl. 59, f. 1; Lesson, Acalèphes, p. 558.

Abundant on the coasts of the North Island, rare near Dunedin.

Velella pacifica, Eschsch. Ac., p. 174, No. 8, pl. 15, f. 4; Lesson, Acalèphes, p. 578.

Abundant on the coasts of the North Island. I have never found it near Dunedin.

Lucernarida.

Lucernaria campanulata, Lamouroux. Johnston, British Zoophytes, p. 248.

A specimen collected by Mr. R. Gillies, at Brighton, near Dunedin, answers very well to the description of this species.

Zoantharia.

Diactis, gen. nov.

Column smooth, divided into two portions, of which the upper is retractile into the lower. Tentacles numerous, subulate, arranged in many rows.

This new genus belongs to the family Antheadæ. Actinia nivea, Lesson (Voy. Coquille, Zoology, chap. xiv., p. 81, pl. III., f. 8), from Peru, probably belongs to it.

D. crocata, sp. nov.

Column: Lower portion longer than broad, expanded at the base, contracted in the middle, pale yellowish brown with numerous white longitudinal streaks; upper portion shorter and narrower than the lower, yellowish orange, very faintly streaked with lighter, and getting brown towards the disc. Disc expanded, as broad as the lower portion of the column, circular, concave, yellow-orange. Tentacles numerous, half the diameter of the disc in length, and of the same colour. Mouth small, elongated, white.

Port Chalmers, a single specimen on Boltenia australis.

The body of this animal varies remarkably in form, and is constantly changing its shape. When normally expanded the column is about an inch long. The tentacles are not very sensitive, but can be retracted with the upper part of the column into the lower part.

Peachia carnea, sp. nov.

Column flesh colour; semi-transparent with pale longitudinal lines, contracted below the mouth, and again about one-third from the posterior end, but the form is variable; anus large and conspicuous. Disc pale flesh-colour, rayed with brown. Mouth raised, surrounded by a brown-banded ring, on one side a number of small papillæ. Tentacles twelve, rather longer than the diameter of the disc, simple, pale flesh-colour with about five brown, often chevroned, bands on the upper surface.

Length about 1 3/4 inch.

A single specimen picked up on the Ocean Beach, Dunedin.

Leiopathes glaberrima, Esper. Pflanzenthiere, II., p. 160, Gorg. pl. 9; Milne-Edwards, Coralliaires I., p. 322.

A large species of Leiopathes, closely resembling L. glaberrima, is found on the West Coast of the South Island. There is in the Museum a fragment, more than two feet long, from Martin's Bay, but as the coenenchyma is totally absent, it is impossible to identify it.
