69 
cavern bears (Ursus spela^us^ Ursus priscus^ 
Ursus arctoideus) ; and a skull of the cavern 
Hyaena (H. spelcea), exhibiting the callus of a 
healed fracture. These form part of the in¬ 
teresting suite (Cases 7 and 8.) of osseous re¬ 
mains from the caverns of Sundwig, and of 
Gaileureuth and Muggendorf in Franconia ; as 
also from the Kirkdale cave in Yorkshire: the 
latter presented by W. Salmond, Esq. 
The scarce remains of birds in this collection 
(Case 41 in the window) include some interest¬ 
ing specimens from Oeningen, the plaster-quar¬ 
ries of Paris, and Sheppey, such as the Larus 
ToUapecus^ &c. 
Among the bones of the class of reptiles (in 
the Cases opposite the fire-place), the most in¬ 
teresting are those of several species of Ich¬ 
thyosaurus, a genus of the order of Lizards 
^(^Sauri), to which we have given that name on 
account of its having been first mistaken for a 
fish by Chapman and others. Particularly re¬ 
markable are the skull and carpal bones of the 
foot of Ichthyosaurus immanis^ (the largest spe¬ 
cies we are acquainted with) from the blue lias of 
Lyme Regis, and Bath:—the bones of another 
huge lizard belonging to a genus intermediate 
between the Monitor and Guana, from Maes- 
tricht;—the unique specimens (Case 41 in the 
window,) of Crocodilus priscus^ and of Lacer- 
ta gigantea of Soemmerring (Geosaurus Cuv.).
