Bivalve and univalve mollusca seem to be rare at the greatest depths; but starfishes, sea urchins and other echinoderms, zoophytes, sponges, and protozoa abound.

However, more and more still would come in a day or two, perhaps whole acres, even whole leagues, and then (so we hoped, but hoped in vain) we should have our feast of zoophytes, crustacea, and what not.

It was the first time that Elsley had ever seen one of those exquisite zoophytes which stud every rock and every tuft of weed.

"When the cholera comes here as it will, at its present pace, before the end of the summer, then I shall have the zoophytes rising up in judgment against me, if I have not profited by a leaf out of their book.

I wonder if the sea-nymphs love their Tritons because those zoophytes must necessarily be so cold!

But the rarer forms of Actinias, Star-fishes, Sepioles, Madrepores, Annelidae, and Zoophytes, of a thousand shapes, live on the bottom, in deep water, and must be captured there.

Sea Pens are termed locomotive zoophytes, and swim in the manner of fish.

Here, too, is a favorite haunt of the beautiful zoophytes, Hydra vividis and H. vulgaris, whose delicate tentacles may be seen gracefully waving in nearly every gathering.

7. Among the distinctive circumstances of the strata, the remains of organized bodies, shells, corals, and other zoophytes, the bones and teeth of animals, fossil wood, and the impressions of vegetable stems, roots, or leaves, etc., are of the greatest importance; affording generally the most marked characters of the strata in which they occur.

She is to observe Mediterranean zoophytes, and send them home on glass slides for the family benefit.

NEW ZOOPHYTES.

Two days afterwards, the weather being extremely favourable for the purpose, I got several hauls with the dredge in forty-five fathoms, sandy bottom, and, in addition to many curious crustacea and shellfish, a number of very fine zoophytes, almost all of them new to science, were in such abundance as quickly to fill the net.

Having left Captain Stanley's party on their way to the lighthouse, I found on the western side of the island a long sandy beach strewed with marine rejectamenta, among which were many new species of zoophytes; the number and variety of sponges was very great, but nearly all had suffered so much from exposure to the sun and weather, as to be useless as specimens.

By dredging, however, in some of the sandy channels among the coral patches, in two or three fathoms water, some small Mitrae, Nassae, Subulae, and other interesting shells were procured, but no zoophytes came up in the dredge, and hardly any crustacea.

They have been derived from the examination of Mr. Darwin's and Dr. Hooker's collections, placed at my disposal by the kind liberality of Mr. Darwina considerable collection of South African species mainly procured from Mr. Bowerbankand from the Collection of British and exotic Zoophytes in the British Museum, for the freest opportunities of examining which I have to thank Mr. Gray.

The method according to which the Polyzoa are arranged, is, in the primary divisions at least, pretty nearly identical with that indicated in the Synopsis of the Families and Genera of Polyzoa Infundibulata, given in Dr. Johnston's British Zoophytes.

Parasitic on several zoophytes.

... SERTULARIAN ZOOPHYTES.

The number of species of Sertularian Zoophytes comprised in this collection amounts to thirty-one, belonging to five genera, all of which appear to be common to both the Northern and Southern hemispheres; and four are European types.

The mode in which the species are arranged will be seen from the following synoptical arrangement: - SYNOPTICAL ARRANGEMENT OF THE GENERA AND SPECIES OF SERTULARIAN ZOOPHYTES COLLECTED ON THE VOYAGE OF THE RATTLESNAKE.

Circumstances having prevented the insertion here of descriptions of new species of Lunulites (Table 1 figures 13 to 16) and a few other Zoophytes of the Voyage of the Rattlesnakeexamined by Mr. Busk subsequently to the preceding paper having been placed in the printer's handsI may mention that the descriptions in question will shortly be published elsewhere.
