Xx1V INTRODUCTION. 
Egerton, now in the British Museum, form the most ex- 
tensive series of Fossil Fishes from the English Lias 
hitherto obtained, and include many type specimens de- 
scribed by Agassiz and Egerton. The Warwick Museum 
has a noteworthy collection from the Lias of the district ; 
the Leicester Museum possesses a_ typical series of 
Fishes and Reptiles from Barrow-on-Soar, lately much 
extended by the researches of the curator, Mr. Montagu 
Browne, F.G.S.; and the fine collection of the late Mr. 
William Lee, made in the same locality, is now in the 
Dublin Museum of Science and Art. The collection of 
the late Mr. Charles Moore, F.G.S., in the Bath Museum, 
comprises an extensive series of similar fossils from Somer- 
setshire and Gloucestershire, all in an unusually fine state 
of preservation. The Upper Lias of Whitby is well repre- 
sented in the Museums of that town, Malton, and York, 
as also in the British Museum. Foremost among the 
collectors may be mentioned the late Messrs. Ripley and 
Brown Marshall, of Whitby; and, as the result of re- 
searches pursued for a period of fifty years, Mr. Martin 
Simpson, curator of the Whitby Museum, has been able to 
define the stratigraphical horizonsin which the remains occur, 
besides adding many specimens to the local collection.* 
The most extensive series of remains from the Lower 
Oolites are those in the Oxford Museum, the British 
Museum, and the private collections of Mr. James 
Parker, F.G.S.,. of Oxford, and Mr. Thomas. Jesson, 
F.G.S., of Northampton. The Middle and Upper Oolites 
are especially represented in the British Museum, the 
Museums of Cambridge and Oxford, and the private 
collections of Mr. Marshall Fisher, of Ely, and Mr. 
Alfred N. Leeds, of Eyebury, near Peterborough. Mr. 
Fisher has obtained a large series of remains, especially 
marine Reptilia, from the Kimeridge Clay of Ely; and
