70 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Dee. 8, 
suggested 50 fathoms as a more appropriate measure. He remarked 
on the great vertical range of some simple corals, such as Caryo- 
phyllia 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 other- 
wise of 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.

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,

August 1869, but has subsequently undergone considerable revision.
