REPTILES.

 cataphractus, Cuv. Oss. Foss. v. t. b,f. 1,2. Gray, S. 59. Dum. et 

 Bib. E. G.w. 126.

 er pairs smaller.

Journey's False Garial. Mecistops Journei. Crocodi- 

 lus intermedius, Graves, Ann. Sci. Phys. ii. 248. Gray, Syn. 59.

 1,2, £.3,/. 1—5. 



Jaws elongate, subcylindrical, without any ridges, flat in front; 

 nuchal plates small, 3 pair, far apart ; cervical plates 3 pair ; dor- 

 sal shield furrowed, squarish, with 2 series of lateral ones. 



a. Very young, in spirits. New Guinea. From the Leyden col- 

 lection. 



3. Crocodilus. 



Jaws oblong, depressed, tapering, rather dilated at the end. 

 Teeth unequal, lower canines fitting into a notch in the side of 

 the upper jaw. Feet fringed. Toes webbed to the tip. Nuchal 

 and cervical plates forming a disk separated from the dorsal one 

 by small granular scales. The head of the newly-hatched speci- 

 mens is short, but it gradually elongates, and after a short time 

 attains the form proper to the species, and through the bones be- 

 coming more solid by increasing age, they only slightly alter the 

 relative proportions of the different parts ; so that the form of the 

 head, taken with the shielding of the back, affords good characters 

 for the determination of the species. 



* Dorsal shields 8-rowed, oblong, longer than broad, subequal, in 

 regular equal series. The small plates on the side in two lon- 

 gitudinal parallel lines. Nuchal shields small or none. Muzzle 

 fiat, narrow, with 2 long parallel ridges in front. Asia. Oopholis.
