I have already in my former Reports on Fossil Polyzoa, 1882 and 1883, 

 given the history of this group, both as Entalophora and Spiropora, in 

 strata of the Mesozoic and Palaeozoic ages. All that remains for the 

 present report are the species described in the Upper Cretaceous and Tert. 

 rocks of America and Europe. I cannot however furnish, from my own 

 knowledge, a very detailed list ; excepting a few of the species described 



1 ' Quite agreeing with the specimens from the Maestricht beds of Fauquemont ' 

 (Roemer).
