Now, in the Retepora and Adeonella materials studied by me and 

 which are contained in the collection of the Zoological Institute, Science 

 College, I have found the six species marked with asterisk in the 

 above list, besides the following nine forms which are to be added as 

 new to the Japanese Bryozoan fauna : 



1. Retepora pacifica japonica, n. subsp. 



2. R. misakiensis, n. sp. 



3. R. watanabei, n. sp. 



4. R. monilifera umbonata MacGillivray. 



5. R. tessellata Hincks. 



6. R. phœnicea Busk. 



7. R. (Reteporelld) kinoshitai, n. sp. 



8. R. [Reteporelld) crenulata, n. sp. 



9. Adeonella hexangulai'is, n. sp. 



In fact, there are contained in the Zoological Institute collection 

 thirteen species of Retepora and two of Adeonella, as reported on in 

 the following pages.
