This list of liassic corals, taken from the Monograph of Dr. 

 Duncan, in the Memoirs of the Palseontographical Society, vols. 

 xx. and xxi., with some additional notices by Eev. P. B. Brodie, 

 shews how many unexpected discoveries have been made in un- 

 likely situations. On a first view the liassic limestones and shales, 

 owing- to the manner of their laminated and often muddy accretion, 

 seem little likely to yield actinozoan remains. But, in fact, Lyme 

 Regis, Street, Sutton, Evesham, Wilmcote, and Fenny-Stratford 

 have rewarded several investigators of fossil corals. The Mono- 

 graph of Dr. Duncan shews them to be generically all distinct from 

 the earlier types of the palaeozoic age, and for the most part identical 

 with genera of the later oolites. The transverse plates of the old 

 rugose corals, and the fourfold division of their calyces is lost, while 

 the newer sixfold division of calyces is not completely established. 



In the district now under consideration these corals are found 

 in the lower part of the lias, chiefly in beds associated with Am- 

 monites angulatus, but some are met with in higher zones, especially 

 at Fenny-Compton. Most of the genera are such as might be 

 expected to occur scattered in sea deposits formed at considerable 

 depths, not collected in reefs.
