68 AMEBIC AN FOSSIL BKYOZOA. [bull. 173. 



It might be expected that the Coal Measures, from the mode of their 

 formation, would not yield many bryozoa. Not many individuals 

 comparatively have been found, yet 62 species assigned to 15 genera 

 have been recorded. The Fenestellidai are still the most numerous. 

 The Permian, perhaps because it has been but little investigated, has 

 but few species. The close of the Paleozoic sees the extinction of its 

 bryozoan fauna. The next fauna in America, the bryozoa from the 

 Cretaceous marl of New Jersey, wears an entirely different facies. The 

 Trepostomata and Cryptostomata are scarcel}^, if at all, represented; 

 the Cyclostomata are numerous, and the Chilostomata even more so.
