with the exception of the great Omosauriis, due to the 

 generosity of the Directors of the Swindon Brick and 

 Tile Company,* the British Museum owes all its finer 

 Reptilian fossils from the Kimeridge Clay of more southern 

 areas to the researches and liberality of Mr. J. C. Mansel- 

 Pleydell, F.G.S., who has also presented a Pliosaurian 

 paddle to the Dorchester Museum. The late Dr. Henry 

 Porter, of Peterborough, obtained various Teleosaurian, 

 Ichthyosaurian, and Plesiosaurian fossils from the Oxford 

 Clay of that neighbourhood, now for the most part in the 

 Woodwardian Museum, Cambridge ; and the unrivalled 

 collection of Mr. Alfred N. Leeds, made in the same 

 locality, comprises not only Dinosauria and numerous 

 nearly complete skeletons of Teleosauria, Ichthyosauria, 

 and Plesiosauria, but also many fish-remains. 



The Purbeck Vertebrata of Swanage seem to have 

 been first systematically collected by the late Messrs. 

 W. R. Brodie and C. Wilcox, and the formation is well 

 represented in the Museums of London, Cambridge, and 

 Dorchester. The most extensive series of Mammalian 

 fossils and the remains of dwarf Crocodiles, now in the 

 British Museum, were discovered by Mr. S. H. Beckles, 

 F.R.S.; and, as the result of systematic purchases, the 

 late Earl of Enniskillen and Sir Philip Egerton accu- 

 mulated the unique collection of P'ossil Fishes from the 

 same horizon, now also in the British Museum. Fossil 

 Fishes likewise occur in the Purbeck Beds of the Vale of 

 Wardour, Wiltshire, and were collected many years ago 

 by the Rev. P. B. Brodie, F.G.S., and more recently by the 

 Rev. W. R. Andrews, F.G.S., of Teffont, in whose private 

 collections the majority are still preserved. 



The Vertebrata of the Wealden were first collected in 

 the classic neighbourhoods of Cuckfield and Hastings, in
