412 AMERICAN FOSSIL BRYOZOA. [buix.173. 



STICTOPORA Hall— Continued. 



1897. Not Stictopora. Grabau, Bull. Buffalo Soc. Nat. Sci., VI, 1899, p. 172 

 (=Cystodictya). 

 Obs. This name has been applied to a number of unrelated forms. A 

 description and figures of the internal structure of the genotype have 

 never been published. Thin sections of S. elegantula show that the 

 genus is related to both Stictoporella and Tfeniodictya. It resembles 

 the former in the long primitive portion of the zooecial tubes, but is 

 distinguisljed by the well-marked peristomes and absence of mesopores. 

 From the latter it differs in the absence of hemisepta, the presence of 

 peristomes, and the long primitive portion of the zooecial tubes.
