E. 3892 (Leeds Coll. 9). A great part of the vertebral column of a large individual. The vertebra; 

 preserved are six cervicals (the atlas and axis are wanting), fourteen dorsals, one lumbar, 

 two sacrals (text-figs. 51-53), and twenty-one caudals. Most of the vertebra?, though 

 somewhat distorted, are well preserved, and in most the neural arches and spines aro 

 present.
