Swedenbourg, from Altenstein, De Cupro Tractat. PI. n. ; and one 
from the mines of Rothenbourg, near Saal, at the depth of 264 feet ; 
M. Cuvier was satisfied that the traces here preserved are of animals 
of the same species. 
The form of the head, the pointed teeth, the size of the vertebrae of 
the tail, would be sufficient, he observes, without the limbs, to show 
decidedlv that this animal must have been an oviparous quadruped. 
The head, however, does not, as was supposed by Spener and Link, 
bear any resemblance to that of the crocodile of the Nile. So far, 
also, is it from being, as is asserted by M. Faujas, a real Gavial, that 
M. Cuvier is convinced, that it differs more from the Gavial than 
from any other reptile of the lizard tribe. 
From the head engraved by Spener, M. Cuvier was enabled to 
determine the genus to which this animal belonged. In the upper 
jaw he could discover only eleven teeth on one side, and which only 
reached to the anterior angle of the orbit ; a circumstance which cha- 
racterizes the Lacerta monitor of Linn feus, or Tupinambis of Daudin. 
In the upper jaw of the crocodile there should be at least fifteen teeth 
on each side, and these should reach to the middle of the orbit. 
The hind feet also, as seen both in Link’s and Swedenbourg’s speci- 
mens, show five unequal toes, of which the fourth is the longest : these 
toes have the following number of bones in each, beginning with the 
great toe, and reckoning the metacarpal bone — 3, 4, 5, 6, 4. This 
number, and this proportion of the toes, as well as the number of the 
joints of each toe, are exactly the same in the Monitor, in the common 
lizards, and in the iguana ; but are different in the crocodile, which 
has but four toes to the hind feet, differing but little in their length, and 
being formed by bones disposed in this number and order — 3, 4, 5, 4. 
The fore feet are discoverable in the specimen of Link, and have 
each five toes of nearly equal size. The crocodiles also, as well as the 
lizards, have five toes to their fore feet, but the little toe is evidently 
smaller in proportion.
