ACTINOZOA. 
49/ 
One Mediterranean species not known in Cainozoic deposits, viz. Amphi- 
helia oculatay Linn., sp. 
Three species belonging to the deep-sea fauna of Florida and Havana, 
viz. : — BalanophyUia socialis (Pourtales), Amphihelia profunda (Pourtales), 
and Pliohothrus symmetricus (Pourtales). 
Lastly, three species known only on the area dredged or in the neighbour- 
ing seas, viz. : — Amphihelia atlantica^ Duncan ; A. ornata, sp. n., Duncan 
Allopora oculina, Ehr. 
* Norna^ Expedition. — Mr. W. S. Kent enumerates Caryophyllia smithif 
Stokes, Eesmophyllum crista-galli, M.-Edw., Lophohelia prolifer'a, M.-Edw., 
Amphihelia oculata, M.-Edw., and Dendrophyllia ramea, Blainv., as taken off 
the coasts of Portugal, /Vnn. N. II. (4) vi. p. 459. 
Classification. — Verrill proposes to unite the following families into a sub- 
order, Oculinacece^ intermediate in many respects between Madreporacece and 
Astrceacece, 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 Oculinacece. Families : 1. Stylasteridce, 2. Oculinid<s, 3. Focillo- 
poridce, 4. Stylophorida;^ 5. (?) Stylinid<x, G. Astrangida;.^ 7. Caryophyllidee. 
The Pocilloporidce 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 Hy- 
droid Corals. (See also Proc. Ess. Inst. vi. pt. 1, p. 90.) As to CaryophyU 
lidce, the typical genera Caryophyllia, Paracyathus, &c. seem to belong here, 
as they have soft parts with the same general structure as in Oculina, As- 
trangia, &c. ; but Flahellum, like Euphyllia, seems better to agi-ee with 
Astreeacece. 
Mr. W. S. Kent likewise disputes the theory that all the ^Habulate ” 
Corals are to be regarded as the skeletal productions of Hydrozoa (Ann. 
N. H. (4) Nov. 1870, p. 386). 
Madreporaria aporosa. 
Turbinolidce. 
Duncan (/. c. p. 292) includes as varieties of Caryophyllia borealis, Flem., 
the old species C. clams, C. smithii, and C. cyathus, 
Mr. W. S. Kent, while agreeing with Dr. Duncan that Caryophyllia 
smithi, borealis, and clavus are merely varieties of the same species, does not 
think that there are sufficient gTounds for uniting with these, as Dr. Duncan 
proposes, the Mediterranean C. cyathus (Ann. N. II. (4) vi. p. 469). 
Caryophyllia sinuosa, corona, and protei, spp. nn., from the Antilles : 
Duchassaing (/. c. p. 24). 
Paracyathus humilis, sp. n,, Verrill (Tr. Conn. Ac. i. p. 638), Pearl Island. 
Desmophyllum crista-galli, M.-Edw. With this should be united D. riisii, 
Michelotti (Kent, Ann. H. (4) vi. p. 469). 
Desmophyllum simplex, sp. n.,Verrill (Am. J. Sc. xlix. p. 371), St. Thomas, 
West Indies.

/. c. p. 293).
