of the wall of the ocecium possesses pores similar to those of the 

 oceeium, and the wall of the ocecium is easily seen to possess more 

 numerous and larger pores than does the wall of the zooecia. 



There are included in this report three families, eight genera, 

 and twenty-one species. Of these, one genus and eight species 

 are new to science. The new genus, Crisiilipora, has puzzled the 

 writer from the fact that it possesses characters which relate it to 

 two families, to both the Crisiiilac and to the Tubuliporidae. Its 

 zorecial and ocecial characters, however, seem to relate it more 

 closely with the Tubuliporidae, where it is accordingly placed. 

 The remaining new species are formed strictly upon ooecial 

 features described above, and in conformity with the investiga- 

 tions and judgment of the later bryozoologists. Of the species 

 reported, twelve are restricted to this coast, five are cosmopolitan, 

 two are circnmpolar, while two are reported from Australian 

 waters. As in the case of some of the Ckilostomata, a few of 

 the species seem to follow the coast line of America, being 

 reported from the eastern shore of South America as well 

 as from our shores, and if search were made for them, it is 

 probable they would be found also on the west coast of South 

 America.
