Miscellaneous. 239 siibulatorum verrucosorum apice globoso Isevi non retractilium plu-ribus (3-4) circumdato. 4. Ulocyathus arcticuSy the only species, was taken at Oxfjord in Finmark, at a depth of 150-200 fathoms, perfectly free, upon a bottom of clay and mud. The largest specimen met with was 1^ in. (Paris) in height and 1^^ inch in its largest diameter. The smallest specimen measured about \ an inch in each of these direc-tions. The colour of the animal is bright minium-red, with the inner tentacles darker, and the folds of the mouth blood-red or brownish-red. The polype is quite solitary, and resembles an Actinia in appearance, but the base of the coral is naked. — Fauna Littoralis NorvegicBy livr. ii. pp. 63-79. Natural History of the Conway Reef. By John Denis Macdonald, Assistant-Surgeon H.M.S. Herald. Gasteropoda. — A.fter a little search, we obtained one recent Stomatella of small size, with a white, polished shell ; Cyprcea an-nulus (young), and a species of Vermetus; but, besides these, no other living Gasteropods were observed, although it cannot be doubted that many exist. Amongst the dead shells, however, which had been washed up from the deeper parts, more especially on the northern side of the Sandy Islet, we noticed a great profusion of a species of Turbo, apparently identical with that which is so conspicuous in the elevated coral terraces of the Isle of Pines. Examples of the following genera were also noticed, though in smaller quantity : viz. Pyramis and Conus, a very large species of each ; Conus generalis, and one or two others ; Triton tritonis, Do-Uum perdix, and Cyprcea, several species. CoNCHiFERA. — With the exception of the genus Tridacna, two species of which were everywhere to be found, no Conchifera seemed to exist on this reef. Crustacea. — Species of the genera Pisa, Portunus, Pyremela and Sesarma were taken on the verge of the Sandy Islet, with a single member of the genus Squilla. Annelida. — Dorsibranchiate and Tubicolous kinds numerous. EcHiNODERMATA. — Thcsc embraced examples of the genera Echinus, chiefly occurring in the deeper parts amongst the branches of Madrepores, Ophiocoma, Holothuria, and Sipunculus, the latter belonging to the small coral-perforating division. TuRBELLARiA, Dendroccela. — Plauarise of comparatively large size. Phytozoa. — AstrcBa, Caryophyllia and Madrepora in great variety, with Nullipores and small Sponges. Alg^. — Nearly all the Algse are small, and require microscopic examination ; the total absence of any of the larger kinds is very remarkable. The Sandy Islet is mainly composed of disintegrated coral and marine shells ; and in several superimposed and sloping layers of
