ACTINOZOA. 497
One Mediterranean species not known in Cainozoic deposits, viz. Amphihelia
oeulata, Linn., sp.
Three species belonging to the deep-sea fauna of Florida and Havana,
viz.:—Balanophyllia socialis (Pom-tales), Amphihelia profunda (Pourtales),
and Pliobothrus symmetricus (Pourtales).
Lastly, three species known only on the area dredged or in the neighbouring
seas, viz. :—Amphihelia atlantica, Duncan; A. ornata, sp. n., Duncan
Allopora oeulina, Ehr.
' Noma' Expedition.—Mr. W. S. Kent enumerates Caryophyllia smithi,
Stokes, Desmophyllum crista-galli, M.-Edw., Lophohelia prolifera, M.-Edw.,
Amphihelia oeulata, M.-Edw., and Dendrophyllia ramea, Blainv., as taken off
the coasts of Portugal, Ann. N. H. (4) vi. p. 459.
Classification.—Verrill proposes to unite the following families into a suborder,
Oculinacea, intermediate in many respects between Madreporacea and
Astraacea, having, as in the former, the polyps exsert, and with their
tentacles swollen at the tips,—as in the latter, the corals imperforate and
compact:—
Suborder Oculinacea. Families: 1. Stylasterida, 2. Oculinida, 3. Pocilloporida,
4. Stylophorida, 5. (?) Stylinida, 6. Astrangida, 7. Caryophyllida.
The Poeilloporida are here included, though they have transversely septate
or tabulate corals. Observations on the polyps show that the family has
the structure of Madreporaria, and no affinity with Millepora or other Hydroid
Corals. (See also Proc. Ess. Inst. vi. pt. 1, p. 90.) As to Caryophyllida,
the typical genera Caryophyllia, Paracyathus, &c. seem to belong here,
as they have soft parts with the same general structure as in Oeulina, Astrangia,
&c.; but Flabellum, like Euphyllia, seems better to agree with
Astraacea.
Mr. W. S. KENT likewise disputes the theory that all the "tabulate "
Corals are to be regarded as the skeletal productions of Hydrozoa (Ann,
N. H. (4) Nov. 1870, p. 386).
MADREPORARIA APOROSA.
Turbinolidce.
DUNCAN (I. c. p. 292) includes as varieties of Caryophyllia borealis, Flem.,
the old species C. claims, C. smithii, and C. cyathus.
Mr. W. S. KENT, while agreeing with Dr. Duncan that Caryophyllia
smithi, borealis, and clams are merely varieties of the same species, does not
think that there are sufficient grounds for uniting with these, as Dr. Duncan
proposes, the Mediterranean C. cyathus (Ann. N. H. (4) vi. p. 459).
Caryophyllia sinuosa, corona, and protei, spp. nn., from the Antilles:
Duchassaing (I. c. p. 24).
Paracyathus humilis, sp. n., Verrill (Tr. Conn. Ac. i. p. 538), Pearl Island.
Desmophyllum crista-galli, M.-Edw. With this should be united D. riisii,
Michelotti (Kent, Ann. H. (4) vi. p. 459).
Desmophyllum simplex, sp. n.,VerriU (Am. J. Sc. xlix. p. 371), St. Thomas,
West Indies.
Flabellum laciniatum, M.-Ed. & Haime, = Uloeyathus arcticus, Sars (Duncan,
I. c. p. 293).
