able to discuss the position of liis species without further exami- 

 nation, but think most will fall under BcrwpoceMaria, though 

 Cellularla cirrata and C. quadrata may have to be placed in 

 another family. 



If a name which has been used in such various ways can now 

 be buried for ever, it will be a great gain, and it now seems 

 quite superfluous. 



Among other points mentioned in the present communication 

 is the existence o£ ovicells on the erect tube of Aetea, a genus 

 which has always been described as without ovicells. 



The stalk of CUidonia Gordieri exhibits a very curious struc- 

 ture ; for the central parenchym-cord gives off a branch to a disk, 

 about the middle of each internode. 



In Bugula plumosa there are cases of long tubes starting from- 

 the lower part of the colony, having much the same appearance 

 as the radicals, but at the end they produce a polypide, and in 

 this way a new colony may arise. 



Although sections have been cut wherever there was suitable 

 material, the gland-like bodies have not been found in any of the 

 groups under consideration ; and I may now mention that nearly 

 all tlie truly calcareous species have these glands, whereas none 

 have been found in the corneous ones. 



Before proceeding to the special descriptions, I must express 

 my warm thanks to the owners of the small zoological laboratory 

 in Kapallo (Professors L. Camerano, M. G. Paracca, and D. liosa 

 of Turin), for kindly placing it at my disposal during my three 

 weeks' stay in Eapallo in March 1893 ; and specially thank 

 Dr. Paracca for the trouble he took in seeing that arrangements 

 were made. This was rather too early for satisfactory work, as 

 a large number of the specimens brought in were not living, or 

 were in an unsatisfactory condition for showing minute structure. 

 This, however, was not the case with all ; and I was enabled to 

 see the gland-like body in a large number of species, and also 

 to study the interzooecial connexion in^many. 



The list of species collected some years before from the sea- 

 weeds thrown up on the beach was almost doubled, as the dredge 

 brought up specimens which would easily be overlooked among- 

 the seaweed. The ground is mostly mud, and the neighbourhood 

 cannot be called favourable for Bryozoa. The best places for 

 dredging are where the mud ceases, about two or three miles out ; , 

 and probably a better locality for the larger coral-like forms 

 such as Porella cervicornis, Hornera, would be near Camogli,,.
