considered a distinct genus, bearing the name of jEolodon) 
from the lias at Monheim in Franconia, being the unique 
specimen described and figured by Soemmerring in the 
Memoirs of the Academy of Munich, under the name of 
Crocodilus priscus ; — a portion of the head, with the 
snout, &c., of a gavial (Teleosaurus Chapmanni) from 
Whitby, which, though correctly determined by its dis¬ 
coverer, Capt. W, Chapman and also by Wooller (Phil. 
Trans, for 1758), was subsequently mistaken for a species 
of Ichthyosaurusa head of Crocodilus Toliapicus , 
mentioned by Cuvier as Crocodile de Sheppy ; —the head 
and other parts of the Geosaurus (the Lacerta gigantea 
of Soemmerring) found together with the preceding, and 
first figured and described by the last mentioned naturalist 
in the Transactions of the Academy of Munich;—the lower 
jaw and other parts of the cranium, vertebrae, &c., of the 
huge reptile (Mososaurus Sancti Petri ) from the St. Peter's 
Mountain near Maestricht, presented, in 1784, by the 
celebrated Peter Camper, and figured by Cuvier;—a por¬ 
tion of a new species, from Lyme Regis, of the remarkable 
genus of flying reptiles, the Pterodactylus of Cuvier, 
described and figured by Buckland in the Transactions of 
the Geological Society, under the name of P. macronyx ; 
together with a coloured cast of the unique P. longu'ostris 
of Cuvier from Solenhofen, the quarry of which place has 
also furnished the small lamina of lias on which may be 
observed the impression, with some of the osseous substance 
remaining, of thejast two articulations of the toe of a flying 
animal, considered by Spix as related to the Vampire, but 
which is more probably a large and distinct species of pte- 
rodactyle. 
The order of Enaliosauri is confined to the genera 
Ichthyosaurus and Plesiosaurus , among the exhibited spe¬ 
cimens of which are—a very perfect head (formerly in 
the museum of Mr. Bullock) of a pretty large specimen 
of the Ichthyosaurus communis; a full length specimen 
of the same (in a separate glass Case): the restored parts 
distinguished by a colour different from that of the genuine 
portion of the skeleton ; part of the head of another of 
still larger dimensions, cut transversely to show the internal 
structure of the jaws; the carpal bones of one of the ex¬ 
tremities of a most gigantic species (Ichthyosaurus im~
