APPENDIX. 
CATALOGUE OF FOSSILS 
FROM THE 
LIASSIO HOCKS OF ENGLAND AND WALES, 
In preparing the accompanying List of Fossils from the Lias, the attempt 
has been made to include only the well-authenticated species. In studying 
the many published papers where lists of fossils are given, it will be noticed 
that the identification of species by different observers, varies a good deal. 
Thus in two lists of the more abundant fossils from the same locality, many 
names do not coincide, when there is every reason to believe that identical 
species are recorded. This arises in part from the fact that species are 
variable, and that gradations exist between them. Hence, one authority 
applies one specific name, and another authority a different specific name 
to the same fossil. Moreover the synonymy of British and Foreign Liassic 
fossils requires much attention, and this again is a source of the dupli- 
cation of names in different lists. Erroneous identifications have also to be 
guarded against in some of the published lists. The List now given will, it is- 
hoped, be found reliable so far as it goes, the species about which any doubts 
were felt having been omitted, or inserted with a quety. 
The species in the Museum of Practical Geology, identified some of them by 
Mr. Etheridge, some by Messrs. G. Sharman and E. T. Newton, are included 
in the List. Many additional records from particular localities have been 
made from the specimens collected by the writer during the progress of his 
work ; and these specimens, excepting some of the commoner forms, have been 
named by Messrs. Sharman and Newton. Much help has also been given by 
them, and also by Mr. H. A. Allen during the preparation of this List. 
Species recorded in the volumes of the Palaeontographical Society, and 
others preserved in the British Museum of Natural History, in the Wood- 
wardian Museum h.t Cambridge, and in the University Museum at Oxford, 
have been noted. Among other Museums it may be mentioned lhat many 
Lias fossils are to be seen in the Museums at Taunton, Street near Glaston- 
bury, Bath, Bristol, Cardiff, Gloucester, Worcester, Warwick, Rugby 
(School), Northampton, and Leicester. Other specimens are preserved in the 
Dublin Museum of Science and Art. 
The fine collection of fossils made by Charles Moore is preserved in the 
Bath Museum ; that of H. E. Strickland (in part), in the Woodwardian 
Museum; and those made by William Smith, Sowerby, Thomas Hawkins 
(in part), Sir P. Egerton, the Earl of Enniskillen, Davidson, Wright (in part), 
and others, are in the British Museum. 
Among private collections, especial mention should be made of those formed 
by the Rev. P. B. Brodie at Rowington, by Mr. T. J. Slatter at Evesham, 
Mr. R. F. Tomes at South Littleton, near E/esham, Mr. Thomas Beesley
