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

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
