54 STRATA OF TILGATE FOREST. 



From the facts that have been presented to our notice, we may with 

 confidence conclude, that the remains in question belonged to an animal, 

 approaching in its osteological characters to the crocodile, (or perhaps to 

 the genus Monitor of Cuvier,) but differing in many important particulars 

 from the recent species : that they are precisely similar to the bones of 

 the second species of fossil crocodile discovered at Honfleur, and which 

 Cuvier considers as an extinct animal, related to the Gavial or Gangetic 

 crocodile ; lastly, that this species exceeded in magnitude every animal of 

 the lizard tribe hitherto discovered either in a recent or fossil state. 



TEETH AND BONES OF UNKNOWN ANIMALS. 



Associated with the remains of the monitor and turtles above de- 

 scribed, are several teeth and bones, whose characters are too obscure and 

 uncertain to admit of determination, without the aid of more illustrative 

 specimens. A brief description of these fossils is here inserted, not in the 

 hope of being able to elucidate their nature, but to record their existence 

 in the Tilgate beds with a view to future inquiries. 



40. Teeth. Among these are several incisors and molares that 

 have evidently belonged to the same kind of animal ; they are of a very 

 singular character, and differ from any previously known. The molares 

 are of an irregular pentagonal form, their sides channelled and obscurely 

 striated. The masticating surface is perfectly smooth, and rather de- 

 pressed in the centre, and in the largest specimen is 0*8 inch long, and 

 05 wide. They consist of the crown of the tooth only, and are perfectly 

 solid. 



An incisor tooth that appears to correspond with the preceding, is 

 1 -S inch long ; it is slightly bowed, and nearly smooth on the inner sur- 

 face, but externally has a longitudinal ridge which extends down the 

 front. The crown of the tooth is 06 inch long, and 04 inch wide; its 

 sides are angular, and their edges finely crenated. 



41. An incisor tooth of a cuneiform shape, 1*1 inch wide, and 1*4 inch 

 long ; the crown only remains. 



^Vhen perfect, this specimen must have been of a very considerable
