Type. Detached dental plates ; Dritish Museum. 
A very large species, the long axis of the “ u[)])er ” dental plate 
attaining a length of 0-12, and its maximum breadth being about 
O’O.u.j. “ Upper ” dental plate with anterior ridge, extending from 
the outer apex to the inner border, prominent, its summit ungulated, 
jilaced very near to the antero-latcral border. “ Lower ” dental 
jilute much thickened towards the sharply rounded posterior angle, 
and the root e.xteriding beyond ; coronal surface moderately convex, 
faintly exhibiting antoro-posterior elevations and depressions in its 
anterior portion. 
As already remarked by Davis, the association of the two forms 
of large teeth ascribed to this species, both in the Limestone of 
Bristol and Oreton, seems sufficient proof of their pertaining to one 
and the same fish. The so-called genus Vatieinodtm also appears to 
the present writer superfluous, and may bo conveniently deemed a 
synonym of Sandalodm ; indeed the type species, V. vetustas, 
appears almost specifically indistinguishable from (S'. morrisH.
