xi. CETEOSA UR US. 253 



Quite lately other specimens, vertebrae and foot-bones, obtained 

 from the vicinity of Chipping-Norton, have been presented to the 

 Museum by Mr. Neate, M. A., of Oriel College ; and, to complete 

 the history of our acquisitions, Earl Ducie has added a fine 

 humerus found in the solid oolite, entirely free from compression, 

 and almost complete. It is the more valuable, because of some 

 sensible difference of form between it and the two previously dug 

 up at 'Enslow Rocks;' for thus an additional argument arises 

 in favour of the opinion, which for other reasons seems probable, 

 that we have in fact, in the small range of estuarine and marine 

 oolitic beds between Chipping-Norton and the Cherwell, remains 

 of two gigantic animals, both as yet undescribed. 



To these notices which I have collected of the discovery of bones 

 of ceteosaurus in rocks of the Bath oolite series near Oxford, may be 

 added vertebrae and other bones from Essendine near Stamford ; 

 several parts of the skeleton from Blisworth ; a caudal vertebra 

 from Stony- Stratford ; and a vertebra and limb-bones in the Scar- 

 borough Museum, from beds of the same series on the Yorkshire 

 coast. 



In the neighbourhood of Oxford, however, other bones referred 

 to ceteosaurus have been collected from Thame and Garsington, 

 and will be noticed hereafter ; in each of these cases it was the 

 Portland rock which preserved them. I have heard also of others 

 found in the same beds near Cuddesdon. At a greater distance 

 from Oxford, and in deposits of another order in the Wealden beds of 

 Sussex other remains of great reptiles referred to ceteosaurus occur. 

 Thus, as far as we know, this genus was most conspicuous in, perhaps 

 limited to, the oolitic period, for the Wealden may, in questions of 

 this order, be justly regarded as the uppermost portion of the oolitic 

 system, with which it agrees in containing megalosaurus.
