zooecia ; then there is an avicularium on a more or less raised promi- 
nence below the aperture, but somewhat to the side. Smitt’s figures 
of Cellepora ( Discopora ) albirostris would apply very well to the 
early stage of C. sardonica and other species, and determination will 
often only be possible by means of the opercula and mandibles.

Now that I have seen several specimens, and have found the ovi- 
cells and spatulate avicularia, which do not seem to have occurred in 
Mr. Hincks’ specimen, there is no doubt that this is the same thing as 
C. granum Hincks ; for opercula and vicarious avicularia exactly cor- 
respond, and it is an open question whether the earlier name or the 
one with the fuller description should be taken. 
As seen in sections of New South Wales specimens, there are 
12-13 tentacles, and there are glands by the operculum. It now 
seems probable that the C. Boryi Aud. is what I called C. retusa var. 
caminata. 
As I have already pointed out, w T e have a group of Celleporidae 
with the operculum nearly round, and the muscular dots not very 
near the border, a somewhat tubular zooecium with sub-globular ovi- 
cells above the oral aperture, but with the peristome usually extending 
above the ovicells, and the ovicells with a distinct area surrounded by 
elongate or radiating pores ; usually vicarious avicularia. 
In the group are included C. granum H., C. Costazii Aud. r 
C. costata MacG., C. caminata W., C. platalea MacG., C. rota 
MacG., C. rudis B., C. bilabiata B., C. signata B., Lagenipora 
spinulosa H., L. Edwardsii Jull., and Lehythopora Jiystrix MacG. 
Perhaps the synonyms should be further reduced. The Lagenipora 
tuber culata MacG., I believe, is the same as Anarthropora horrida 
Kirkpatrick, and I should not place it with Lagenipora. 
The above group will have to be separated generically; and 
although more weight is now put upon such characters as are 
furnished by the operculum and ovicell, and less on the manner of
