2400. A chevron-bone, provisionally referred to this species ; from 



{Fig.) Cuckfield. Figured by Mantell in his ' Fossils of Tilgate 



Forest,' pi. xii. fig. 4. Same history. 



36514. A later chevron-bone of similar dimensions; from Cuckfield. 



Mantell Collection. Purchased, 1853, 



The following girdle- and limb-bones accord in type with those of the 

 present species, but some of them may belong to the next form, 

 and others of smaller size to Sphenospondylus gracilis. 



40102. The left scapula and left * associated sternal (?) bone ; from 

 the Lower Greensand of Black-Gang Chine, Isle of "Wight. 

 The scapula is somewhat longer than in the type-speci- 

 men, the sternal bone is of the same contour as that of 

 I. bernissartensis, figured by Dollo in the ' Bull. Mus. R. 

 Hist. Nat. Belg.' vol. i. pi. xii. Purchased, 1859. 



2196. A smaller right scapula; from Cuckfield. This specimen 

 agrees very closely with the one figured by Dollo in the 

 4 Bull. Mus. E. Hist. Nat. Belg.' vol. i. pi. ix. fig. 2, 

 although of smaller size. 



Mantell Collection. Purchased, 1838. 



2196 a. The proximal half of a left scapula of apparently similar 

 type, from Cuckfield. Same history. 



R. 115. The proximal half of a right scapula; from the Isle of 

 "Wight. Fox Collection. 



R. 118. A left coracoid; from the Isle of Wight. Agrees very 

 closely with th e specimen figured by Dollo, op. cit. Longest 

 diameter 0,190. Same history. 



2543. Cast of an imperfect left coracoid, agreeing very closely 

 with the preceding, but having a notch instead of a 

 foramen. The original was obtained from Cuckfield, and 



1 This scapula and the undermentioned associated humerus belonging to the 

 left side, the presumption is that the sternal bone is also of the same side. If 

 this be so, it would indicate that Cope's view of the position of the sterna Is 

 mentioned on p. 233 must be correct.
