And from the Pierre jaune (Middle Neocomian) of Landera 

 we also have 12 TJpware and Brickhill species, these beds further 

 resembling our phosphatic deposits in their rich sponge fauna,

The following list also shews considerable relationship between 

 our TJpware beds and the Swiss Aptien.

Thus, from the comparison of our fossils with the various lists 

 of Swiss species, we gain little knowledge of their exact affinity to 

 any one particular zone in the Swiss series.
