Note. — Beside the fossils included in the above list, there is a con- 

 siderable number of other species in the Speeton Clay, not a few of 

 which appear to be altogether new to science. In the case of some of 

 those given, future researches will doubtless show their ranges to be 

 more extended than is indicated in the table.
