FisTULiPORA McCoy 



Fistulipora? sp. 



On the surface of bed V were found Bryozoa, probably of this 



genus, showing the circular shell apertures and the mesopores.

 Fragments of a zoarium referable to this genus were found on 

 the weathered surfaces of bed V. The longitudinal rows of cell 

 apertures with intervening ridges, and the mode of branching 

 are shown, but the specimen is too poorly preserved to be identi- 

 fied with certainty.
