sions. It is well characterized by its median pore placed in the 

 vicinity of the aperture and by the beautiful lateral tuberosities 

 which surround each zooecium like a necklace. The median pore is 

 often invisible and buried in the peristome. Frequently the lateral 

 tuberosities are much attenuated and the costules much less calcified. 

 The interzooecial avicularium is frequent, very long, acuminated, 

 and salient in front of the zooecial plane. 



According to Norman, 1909, this form differs from the typical form 

 only in its much smaller dimensions, its more salient costules, and in 

 its less acuminate avicularium. Smitt, 1872, placed here all the 

 specimens ornamented with a lunate pore. The variations of the 

 two forms being quite large, it is really impossible to distinguish them 

 specifically, and we therefore follow the opinion of Waters. 



The operculum closes the ovicell. The costules are covered by 

 the ectocyst. On the interior the costules are not visible. Only the 

 lumen pores, radially arranged, appear as tremopores. 



Biology. — Our specimens encrust nullipores, dead shells, and corals. 

 The living specimens were in reproduction March 15, 1885. 



We have shown in our work on the Philippine Bryozoa that this 

 species is in reproduction continuously during the entire year.
