OF THE SIVALIK HILLS. 37 



The above is the remain of a smaller animal than the former one, 

 shewing the alveoli and some of the teeth, as far back as the 10th, on each 

 side of the maxillaries. A more perfect resemblance to the living animal 

 than this could not well be conceived ; and it moreover establishes, in the 

 absence of a connected beak and skull, that the fossil animal had pre- 

 cisely the same number of teeth with the living species. The suture con- 

 necting the intermaxillaries with the maxillaries is fortunately strongly 

 marked in the fossil ; the posterior point of the suture occurring opposite 

 the 9th tooth, exactly as it does in the existing animal. The teeth, the form 

 of anterior extremity of muzzle, the outer nasal aperture, with the lower 

 indentations, correspond in every way; and, to descend still further to 

 minutiae, at the commencement of the suture connecting the intermaxil- 

 laries and maxillaries, at a point in the former bone immediately in front 

 of the 6th tooth is a small hollow or indentation : this hollow exists in the 

 same situation and bears the same form in our fossil GhariaL 



Of the lower jaw we have only an imperfect fragment of the two 

 branches connected at the commencement of the symphisis : — from the 

 extreme hardness of the crystalline rock in which it is imbedded, we are 

 unable to see further than that the angle of these branches corresponds with 

 the existing animal, a point however which is proved by the fragments of 

 skull which are in our possession, and which, imperfect as they are at the 

 muzzle extremity, shew distinctly the commencement of that tapering form 

 which is peculiar to the Gliaridl of the present rivers. 



In volume 5, of the Ossemens Fossiles, Cuvier, in recapitulating the 

 peculiarities and differences between the Crocodiles and Gharidls, says of 

 the latter " Les pterygoidiens ferment au dessus des palatins des especes 

 " de grosses vessies renflees et ovales de la grosseur d'un oeuf de poule, 

 " au lieu d'une simple voute cylindrique comme dans les Crocodiles et les 

 " Caimans, &c.," and then " Je n'ai point observe cette vessie dans le 

 " petit GavidI, mais je suppose d'autant plus quelle est un produit de I'age
