150 DINOSAURIA. 



R. 985. Fragment of the worn centrum of an enormous trunk 

 vertebra, provisionally referred to this form ; from Hastings, 

 Sussex. No history. 



R. 209. The right half of the haemal portion of what appears to be 

 a posterior (? last) lumbar vertebra ; from the Isle of 

 Wight. The floor of a large lateral pit remains, and is 

 directed horizontally, while the centrum is internally 

 honeycombed by cavities. This specimen differs very 

 widely from the last lumbar of Cetiosaurus brevis (No. 

 36559) ; it is noticed by the writer in the ' Quart. Journ. 

 Geol. Soc' vol. xliv. p. 56. Fox Collection. 



R. 141. The centra and bases of the arches of three associated 

 posterior caudal vertebrae, probably belonging to this 

 form ; from the Isle of Wight. Same history. 



R. 141 a. Four imperfect posterior caudal vertebrae, probably be- 

 longing to this form ; from the Isle of Wight. 



Same history. 



R. 156. A bone, provisionally regarded as a left posterior sacral rib 

 of this form ; from the Isle of Wight. Noticed by the 

 writer in the ' Quart. Journ. Geol. Soc' vol. xliv. p. 55 ; 

 it apparently corresponds fairly with the rib of the fourth 

 sacral of Brontosaurus figured by Marsh in the ' Amer. 

 Journ.' ser. 3, vol. xxi. pi. xvi. Fox Collection. 



46781. A smaller imperfect bone, of the opposite side, agreeing in 

 structure with the preceding ; from the Isle of Wight. 



Purchased, 1875. 



R. 212. The distal extremity of the left scapula ; from the Isle of 

 Wight. Noticed by the writer, op. cit. p. 55 ; although 

 rather smaller, this specimen closely resembles the corre- 

 sponding part of the scapula of Brontosaurus figured by 

 Marsh in the 'Amer. Journ.' ser. 3, vol. xxi. pi. xii. 



Fox Collection. 



R. 97. The associated right ischium and pubis, in a slightly im- 

 (Fig.) perfect condition; from Brixton, Isle of Wight. The 

 type of 0. eucamerotus ; figured by Hulke in the ' Quart. 

 Journ. Geol. Soc' vol. xxxviii. pi. xiv. These specimens 

 closely resemble the corresponding bones of Brontosaurus^ 

 (fig. 23) ; part of the head of the pubis is wanting. 



Same history.
