E. 2075 (Leeds Coll. 3). Imperfect skeleton of an individual rather larger than the type specimen. 

 The parts preserved are portions of skull and mandible, atlas and axis, five other 

 cervicals, about seventeen dorsals, one sacral and twenty-three caudals, some scutes. 



The two following specimens, in which the skull is badly preserved, are referred 

 provisionally to the present species : — 



E. 2078 (Leeds Coll. 4). An imperfect skeleton of an individual rather larger than the type 

 specimen. The parts preserved are portions of. the skull and mandible, the centra of 

 the atlas and four other cervical vertebrse, six dorsals, two sacrals, and eight caudals 

 (the neural arches in the cervical and dorsal regions are nearly all separated from the 

 centra) ; cervical and dorsal ribs, chevrons, ilia, femora, a tibia and fibula, bones of 

 hind foot, numerous scutes. 



The dimensions (in centimetres) of some of the bones are : —
