Notes on Bryozoa from Rapallo and other Mediterranean 

 Localities. — Chiefly Cellalariidse. By Abthtjr WiLLiAivr

(Plates 1 & 2.) 



Although now at work upon material collected in Eapallo, near 

 Grenoa, it has seemed better to give this paper a wider range, 

 so as to be able to include any observations resulting from com- 

 parison with ray Mediterranean and other collections. In fact, 

 it may be said to include a revision of my paper * on the Naples 

 Bryozoa. 



Greneral questions of structure and classification have received 

 considerable attention, but are only dealt with where there seemed 

 sufficient reason for doing so. 



When I wrote upon the Naples Bryozoa, a very large number 

 of the descriptions, even by the leading authorities, were most 

 unsatisfactory ; nor did I possess my present large collection,, 

 including preparations made in various waysf, so that only- 

 limited comparisons could be made. Since then the student has 

 had for reference, besides a large amount of general literature,. 

 Hincks's well-illustrated work on the British Marine Polyzoa, and 



* Ann. & Mag. Nat. Hist. ser. 5, vol. iii., 1879. 



t In all cases where I have had suitable material, stained sections have 

 been cut, either for minute structure or, when the state of preservation has 

 not been suitable for anything more, for the interzocecial connexions; nor 

 can any series be considered complef until there are stained specimens mounted 

 ■whole, as well as preparations of the opercula and mandible, besides calcareous 

 sections.
