49165. An imperfect bone, which is probably the dorsal half of the 

 right pubis; from the Kimeridge Clay of Weymouth.

The following specimens have been named Gigantosaurus megalonyx 



by Seeley. 



32498. Cast of a fibula, probably belonging to this species. The 



original was obtained from the Kimeridge Clay of Ely, 

 Cambridgeshire ; a similar cast is noticed by Seeley, op. cit. 

 p. 95, and referred to G. megalonyx. 



Presented by G. Bard, Esq., 1857. 



32499. Cast of a terminal phalangeal, agreeing in relative size 



with the humerus. The original was obtained from the 

 Kimeridge Clay of Ely; a similar cast is noticed by 

 Seeley, op. cit. p. 95, and appears to be the type of G. me- 

 galonyx. Same history. 



Omithopsis manseli (Hulke, MS.). 

 Syn. Ischyrosaurus manseli, Hulke (MS.). 



The type of Ischyrosaurus J ; if the type specimen be adult it 

 indicates a much smaller species than the preceding. 

 Hab. Europe (England). 



41626. The left humerus, with the deltoid ridge broken away ; from 

 {Fig.) the Kimeridge Clay (Upper Jurassic) near Kimeridge 

 Bay, Dorsetshire. The type specimen ; figured by Hulke 

 in the ' Quart. Journ. Geol. Soc' vol. xxv. pi. xvi., with- 

 out generic determination, but referred to in vol. xxx. 

 p. 16 as the type of Ischyrosaurus. When entire this 

 bone must have agreed very closely in contour with the 

 humerus of 0. humerocristatus.
