104 CKOCODILIA. 



Machimosaurus mosse, Sauvage & Lienard *. 

 Syn. Teleosaurus mosce, Lienard 2 (MS.). 



The largest known Crocodilian; its distinctness from the type 

 species not very apparent. Typically from the Kimeridgian of 

 Prance. Thirteen lower teeth, of which three or four are postsym- 

 physial ; the length of the mandible is usually about 1,322 (52 in.). 



Hah. Europe (France and England). 



It. 1089. The occipital region of the cranium and the associated man- 

 (Fig.) dible; from the Kimeridge Clay (Upper Jurassic) of 

 Kimeridge Bay, Dorsetshire. The mandible is figured by 

 Owen in his ' Eeptilia of the Kimeridge Clay ' (Mon. Pal. 

 i Soc), pi. xii. figs. 3-5 ( 1868), under the name of Plio- 

 saurus trochanterius. Its crocodilian nature was pointed 

 out by Deslongchamps in his '.Notes Paleontologiques,' 

 p. 329, where it is referred to Metriorhynchus ; and it is 

 mentioned under that name by A. Smith Woodward in the 

 8 Geol. Mag.' 1885, p. 502. The mandible cannot be dis- 

 tinguished from that of the type of the present species 

 figured by Sauvage and Lienard, in the ' Mem. Soc. Geol. 

 Prance,' ser. 3, vol. i. art. 4, pi. xxiii. (iv.) ; but the pre- 

 sent specimen shows there was no terminal expansion of 

 the symphysis ; there are thirteen lower teeth ; the hinder 

 portion of the cranium is essentially of a Teleosaurine 

 type, and agrees with the fragments of the same part in the 

 type specimen. The length of the entire mandible is 

 1,322 (52 inches), the length of the type mandible, as 

 restored by Sauvage and Lienard, to the extremity of the 

 glenoid cavity, being 1,296 (51 inches) ; the length from 

 the posterior extremity of the glenoid cavity to the extre- 

 mity of the splenial is 1,020 (42 inches) in the former, 

 and from the condyle 1,090 (42*6 inches) in the latter ; 

 and the width of the posterior part of the symphysis 

 0,203 (8 inches) in the former, and 0,208 (8-2 inches) in 

 the latter. Presented by J. C. Mansel-Pleydell, Esq., 1866.
