Abstract
So much confusion has occurred in the past over the identification of the genera which we have been discussing, that a list of some figured species from the Jurassic rocks, arranged in their proper sub-genera, may be useful. The only previous attempt at a list of this sort, so far as I am aware, is that by Professor Rollier, who was only able to enumerate five species. He called all these Beushausenia, but two are not Beushausenias but true Parallelodons, while a third belongs to a different genus.Keywords
