LOCALITIES OF FOSSIL ZOOPHYTES. 279 
At Steeple Ashton, in Wiltshire, numerous oolitic corals 
may be obtained. The silicified Astrec, of Tisbury, in the 
same county, deserve particular notice (ante, p. 263). 
Clifton, near Bristol, and Torquay and Babbicombe, on 
the Devonshire coast, are celebrated for their coralline 
marbles and pebbles; and many of the Derbyshire lime- 
stones are equally prolific in similar remains. The Devonian 
marbles are so largely employed for ornamental purposes,— 
as brooches, tables, and side-boards,—that the figures pro- 
duced by the sections of the enclosed corals must be familiar 
to the reader.* 
Dudley, Wenlock, and Ludlow, are well known for the 
abundance and variety of Silurian polyparia. 
Other localities of British corals have been mentioned in 
the course of this review of fossil zoophytes. 
* Specimens of these fossil corals, either as objects of natural his- 
tory, or as ornaments, may be obtained of Mr. Tennant, 149, Strand.
