The formation and locality of the type (Faujas CoU., Paris 
Museum) are unknown, but it was probably derived from 
the Molasso of Maraval, near Castries, Herault. From 
this locality a lower dentition is described and figured by 
P. Gervais, Zool. et Pal. Frang., Poiss. Foss. (1852), p. 15, 
pi. Ixxx. fig. 4 ; an upper dentition by P. Gervais, Zool. 
et Pal. Ge'ncr. (1869), pi. xlvii. fig. 10. Another speci- 
men, either of this species or M. dixoni, from the Faluns 
of Merignac, is described and figured by P. M. Pedroni,
