me a Caryophyllia which was dredged up alive by Captain King 

 from a depth of 80 fathoms off Juan Fernandez, in lat. 33° S. Ellis 

 (Hat. Hist, of Coralline, p. 96) states that Ombellularia was pro- 

 cured in lat. 79° K. sticking to a line from the depth of 236 fathoms ; 

 hence this coral either must have been floating loose, or was entangled 

 in a stray line at the bottom. Off Keeling atoll a compound Ascidia 

 (Sigillina) was brought up from 39 fathoms, and a piece of sponge, 

 apparently living, from 70, and a fragment of Nullipora, also appa- 

 rently living, from 92 fathoms. At a greater depth than 90 fathoms 

 the bottom was thickly strewed with joints of a Halimeda and small 

 fragments of other Nulliporse, but all dead. Captain B. Allen, B.N., 

 informs me that in the survey of the West Indies it was noticed, 

 that between the depth of 10 and 200 fathoms, the sounding-lead very 

 generally came up coated with the dead joints of a Halimeda, of which 

 he showed me specimens. Off Pernambuco, in Brazil, in about 12 

 fathoms, the bottom was covered with fragments, dead and alive, of a 

 dull red Nullipora, and I infer from Eoussin's chart, that a bottom 

 of this kind extends over a wide area. On the beach, within the 

 coral-reefs of Mauritius, vast quantities of fragments of Nulliporse 

 were piled up. From these facts, it appears that these simply or- 

 ganised bodies, belonging to the vegetable kingdom, are amongst the 

 most abundant productions of the sea.
