xiv 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 horizons in 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
