A tooth of llylodus, from the J urassic of Berne, Switzerland, is 
also figured by Thurmann & Etallon, Nouv. Mem. Soc. Helv. Sci. 
Nat. vol. xviii. (1804), pi. Ixi. fig. 11 ; another (under the name of 
Kolidanvs sp.) from the Oxfordian of Switzerland, by E. Favre, 
Foss. Terr. Oxford. Alpes Tribourg. (Mem. Soc. Pal. Suisse, vol. iii. 
1870), pi. ii. fig. 1 : and a doubtful tooth (under the name of 
llylodus personati), from the Braun Jura of Wiirtemberg, by F. A. 
Queustedt, Jura (1858), p. 339, pi. xlvi. fig. 14. 
As already remarked (p. 270) imperfect teeth precisely resembling 
those of llylodus are also described under the name of Meristodon, 
L. Agassiz, Poiss. Foss. vol. iii. (1843), p. 286, the type species 
being O.vyrltina (Meristodon) 2 >arado.va, Agassiz (loc. cit.). Other 
teeth of a similar type, from the Jurassic of Manganischlak, Caspian

Stoliezka, Cretaceous Fauna S. India (Pal. Indica), vol. iv. (1873), 
pt. 4, p. 08, pl. xii. fig. 34. A distinct species, Aleristodon jurensis, 
Sauvago, has also been determined by 41. E. Sauvago from the 
B.ijocian Beds of Montmorot, Jura Jits. (Bull. Soc. Geol. France, [3] 
vol. xi. (1883), p. 480, pl. xii. figs. 13, 14). 
An indeterminable tragment of a tooth of a somewhat similar 
character, from the “Braun Jura «” of Wiirtemberg, is named 
Selachidca tondosi, F. A. Uuenstedt, Ilandb. Petrefakt. 1852, p. 173, 
pl. xiii. fig. 10.
