306 Geology. 



Oxford Clay near Peterborough. His first collection, made in association 

 with his brother, Mr. Charles E. Leeds, was purchased from him by the 

 Museum in four instalments in 1890, 1891, 1892 aud 1893. Several 

 subsequent small purchases have added important specimens to the series, 

 notably a nearly complete Plesiosaurian skeleton in 1897, and the tail and 

 two limbs of a gigantic Dinosaur in 1899. This collection comprises 

 many type and unique specimens of Dinosauria, Crocodilia, Plesiosauria, 

 Ichthyosauria, and fishes, described by J. Phillips, J. W. Hulke, H. G. 

 Seeley, R, Lydekker, C. W. Andrews, and A. S. Woodward.

Lewis (E. R.) 



The late Professor in the Syrian Protestant College, Beyrout, made a 

 large collection of the various organisms found in the Upper Cretaceous 

 of the Lebanon. He specially collected the fishes, and described his 

 work in the Geological Magazine, dec. 2, vol. v. (1878), pp. 214-220. 

 His collection was acquired by the dealer, R. Damon, of Weymouth, from 

 whom the Trustees of the British Museum purchased a first selection in 

 1878, 1883, and 1884. A selection was subsequently purchased by the 

 Edinburgh Museum of Science and Art. The whole collection of fish- 

 remains was described by J. W. Davis ( Trans. Roy. Dublin Soc., ser. 2, 

 vol. iii., 1887). The British Museum possesses the specimens on which 

 H. Woodward founded the species Squilla lewisi and Limulus syriacus 

 (Quart. Journ. Geol. Soc., 1879).

Mr. Lewis, of Aymestry, assisted Murchison in investigating the 

 Upper Silurian of the district in which he resided, and made a large
