IL 2616 (Leeds Ooll. 25*). Portions o£ a skeleton of a large adult individual. In this specimen the 

 bones are quite uncrushed and not distorted : some are scored by deep scratches apparently 

 made by the teeth of some predaceous reptile. The parts preserved are some cervical 

 vertebrEe, mostly with the neural arches, which are just becoming fused to the centra; 

 one sacral and eight caudal vertebr£e, the neural arches in most cases missing, the 

 suture having remained open ; some cervical ribs which had not yet united with the 

 centra, and a number of abdominal ribs of great size and massiveness ; nearly perfect 

 shoulder-girdle and pelvis, and a few odd paddle-bones. The shoulder-girdle has been 

 described and figured in Ann. Mag. Nat. Hist. [6] vol. xv. (1895) pp. 335-340, figs. 1, 

 2 ; also figured on PL X. figs. 1, la, lb, 1 c. The pelvis described and figured in 

 the Qeol. Mag. [4] vol. iii. (1896) pp. 145-148 ; also figured on PI. X. figs. 3, 3 a, 3 b.
