Mr. Waters gives Buskia nitida, Heller, as a synonym, but he does not state 

 that he has seen a type ; without such a specimen, I cannot quote that 

 Adriatic species as identical with the present. Again, he says that his 

 Neapolitan examples have " two avicularian chambers, which overlook the 

 mouth." In my specimens from Naples and Madeira I only see one avicularium 

 of large size as figured by Smitt. I dredged it at Madeira; Senhor DeNoronha 

 procured it on Hydroids from the telegraphic cable; and in the Funchal 

 Museum I found two unnamed specimens in a pill-box with the following 

 note : " ' Brittannia,^ do Cabo," the longer, the shorter " ' Scotia ','' apparently 

 therefore procured from the telegraphic cable. 



Cellepora eotundora, nom. nov. W. (PI. 42. figs. 8, 9.) 



1899. Cellepora ianthina, Waters, Journ. Roy. Micr. Soc. p. 14, pi. 3. figs. 1-3 (nee 

 Cellepora edax, var. iantJiina, Smitt). 



I fail to recognise the species which Waters described from Madeira, and 

 of which I have found numerous examples in about 70 fathoms, on small 

 shells and especially on Ditrujjce, as Smitt^s Cellepora edax, var. iantliina. 

 Smitt^s drawings may be relied upon as accurate, and the Lepralia-like orifice 

 shown in his figure is entirely different from the perfectly round oral opening 

 (rotundus and ora, an edge) of the Madeiran species. The rim is quite circular 

 without any constriction of the margin, but in the throat a little projecting 

 point on each side indicates the place of attachment of the operculum. The 

 ooecium is remarkable with the lower portion of the front quite open, it is very 

 thin, and the ooecia are generally broken down, as represented on the right hand 

 in the figure here given. I leave the species where Waters placed it, but it 

 cannot remain in Cellejjora. The operculum is of unusual form (fig. 9).

The ij^Q specimen of Waters, which is in the Museum at Funchal, is the 

 only example I have seen. It certainly is no Cellepora^ nor do I see its con- 

 nection with Jjepralia,
