MEGALOSAURUS 
the recent, as to leave no reasonable doubt that they 
belonged to some species of Crocodile or Gavial. 
These are portions of the oinoplate^ a humerus, 
radius, head of a tibia, several carpal, and some of 
the phalangeal bones. 
Megalosaurus ; — or Great Lizard of Stones- 
field. This enormous creature, which held an in- 
termediate place between the Crocodiles and the 
Monitors, but is considered to have most nearly 
approximated to the latter, is computed to have 
attained a length of fifty feet. In the highly in- 
teresting memoir of Dr. Buckland, which first made 
us acquainted with the remains of this wonderful 
oviparous quadruped, the learned Pi'ofessor has 
fully detailed its anatomical structure (so far as the 
remains of its skeleton hitherto found would admit) : 
it will, therefore, be sufficient for my present pur- 
pose to notice very briefly its distinguishing cha- 
racters. The principal bones described, consist, 
1st, of a portion of the lower jaw, nearly a foot 
long, containing one tooth fully developed, and the 
germs of many others ; 2dly, a femur ; 3dly, a 
series of five vertebras ; 4thly, a coracoid bone ; 
5thly, a clavicle ? 6thly, ribs ; 7fhly, an ischium ; 
Sthly, metatarsal, or metacarpal bones. The teeth 
are very remarkable (vide fig. 1. p. 26 1.); they 
are compressed laterally, and recurved ; their edges 
are finely serrated, the anterior edge being the 
thickest : the largest tooth is two inches long. They 
are lodged in distinct alveoli or sockets, but do not 
adhere to the jaw, as in the Monitor ; although, like 
the latter, the outer edge of the jaw rises con- 
siderably above the inner margin, and thus forms a
