are figured together by the writer in the * Quart. Journ. 

 Geol. Soc' vol. xlvi. p. 46, fig. 4. The present specimen 

 was obtained in 1889 at a distance of about 180 yards to 

 the eastward of the spot where No. R. 604 d was found in 

 1884. The vertebra, No. R. 604 a (supra, i. p. 166), the 

 tibia R. 604 c (ibid. p. 167), and No. R. 604 d were all 

 found together. Dawson Collection. Purchased, 1889. 



R. 1525 a. An imperfect later caudal vertebra apparently associated 

 with the preceding ; from Hollington quarry. The neural 

 arch is crushed down upon the centrum, and the transverse 

 processes are imperfect. Dawson Collection. 



Megalosaurus oweni, Lydekker \ 



Smaller than the preceding species, with the second metatarsal 

 only slightly longer than the fourth ; both those bones having sharp 

 antero-internal borders, and the distal surface of the fourth being 

 broad and squared. 



This species is founded on the metatarsus No. 2559 (supra, i. 

 p. 167), which really belongs to the right side, the metatarsal 

 described by Owen as the 2nd being the 4th, and vice versa. The 

 metatarsal which was compared in Part I. with the 4th of M. dunkeri 

 is really the 2nd of the right side. No. 2661 (supra, i. p. 168) will 

 be the 4th of the left side ; while Nos. 2680 and 2574 (loc. cit.) 

 belong to the right side. 



The type specimen is from the Upper part of the Timbridge 

 beds, which overlies the Wadhurst Clay, and it is probable that 

 most or all the specimens from these beds at Cuckfield and the 

 Weald Clay of the Isle of Wight, entered in Part I. under the head 

 of M. dunkeri, belong to this species. 



Hob. Europe (England). 



Genus non det. 



It is suggested that the undermentioned specimens may possibly 

 belong to Megalosaurus. 



R. 1412. The axis vertebra and intercentrum of a Dinosaur ; from
