suggested 50 fathoms as a more appropriate measure. He remarked on the great vertical range of some simple corals, such as Caryophyllia Smithii, which extends from low-water mark to at least 150 fathoms. In deep-sea water it is frequently attached to various shells, especially Ditrypa and Aporrhais. Another simple coral of our seas, Desmophyllum (Ulocyathus) arcticum, had not been found at a depth of less than 75 fathoms. Compound corals occurred only at considerable depths.
Dr. Duncan drew a distinction between coral-reef areas and those in which different conditions prevailed. His argument had not so much been based on the depth of the sea as on the presence or otherwiseof coral-reefs. The term deep sea had been given by Prof. Forbes to depths of 10 fathoms and upwards. For such depths as those explored at the present day no term short of "abyssal" was appropriate.

Introduction.
On the 16th of December, 1863, Messrs. W. Vicary and J. W. Salter made an important communication to the Geological Society on the "pebble-bed" at Budleigh-Salterton, wherein some thirty-six different fossils were described and illustrated; of these, ten or twelve were Brachiopoda.
Since that period Messrs. Vicary, Valpy, Edgell, Box, Winwood,
