CROCODILID^. 67 



R. 783 a. The anterior part of the mandibular symphysis. 



Transferred from the Old Indian Museum, 1880. 



39812. The anterior part of the right half of the mandibular sym- 

 (Fig.) physis. Figured by the writer, op. cit. pi. xxx. fig. 5. 



Some of the following specimens may belong to the next species. 



R. 615. Several teeth; from the Siwaliks of the Punjab, India. 



Presented by the Director of the 

 Geological Survey of India, 1886. 

 R. 783 d. A tooth. 



R. 746 a. Several dorsal vertebrae, with the overlying dermal scutes 

 of the right side ; from Perim Island. 



Transferred from the Old Indian Museum, 1880. 



R. 783 b. The palatal plates of the pterygoids and part of the pala- 

 tines. 



R. 783 C. The imperfect hinder portion of the right ramus of the 

 mandible of a very large individual. 



The following specimens probably belong to this genus. 



39813. A mass of dorsal vertebras, together with the dermal scutes 



in an obscure condition. 



39814. A mass of matrix, showing the ventral aspect of a number 



of associated dorsal scutes, belonging to the same form as 

 the preceding. This and the last specimen were referred 

 by Falconer to G. gangeticus, and are too small to have 

 belonged to Rhamphosuchus ; they may have belonged to 

 G. leptodus. 



Garialis hysudricus, Lydekker 1 . 



Distinguished from G. gangeticus by the more marked concavity 

 of the rostrum in advance of the orbits, and probably by the upward 

 curvature of the extremity of the rostrum. The cranium, provision- 

 ally referred to this species, has the orbits more approximated, 

 smaller supratemporal fossae, with a wider parietal bar between them, 

 and a greater lateral expansion of tho jugal and quadrato-jugal 

 region, than in the existing species. The extremity of the rostrum 

 may have been without expansion.
