*Some 25 or more species of Dinosaurs have been reported from the Como stage. Many of these 

 have been established upon a single bone or at most a lew, and beyond question when the animals 

 are better known the number will be greatly reduced. This will not only att'eet species, but genera, 

 and beyond question higher divisions. Only those arc referred to that appear to have an unques- 

 tionable standing.
