colonial growth, they can all stand as Lageniporm. My specimen of 
Lagenipora socialis from Hastings, though rather a poor one with 
only one ovicell, shows that the ovicell has a raised line marking off 
an area, but I am unable to see what the ornamentation is. Hincks 
did not notice the area.

Cellepora janthina Smitt, plate III. figs. 1, 2, 3. 
Cellepora edax var. janthina Smitt, Floridan Bryozoa, p. 63, 
pi. xi. figs. 224, 245. 
Zoarium incrusting, or disk-shaped like Orbitulipora, zooecia dis- 
tinct, short, ovate ventricose, punctured, sometimes with a central 
umbo, and with a triangular avicularia on one or both sides below' the 
oral aperture ; oral aperture very nearly round, with a denticle at each 
side. Ovicells globular, granular, very widely open and much raised. 
In using the name Cellepora, it is recognised that with modifi- 
cation of classification it may have to be placed elsewhere, and Hincks 
has proposed the genus Cyclicopora for forms .with a round aperture ; 
but I am not at present prepared to remove the Madeira form to that 
genus. 
This is much like the Eschara cyclostomata of Moll (non Busk), 
Seerinde, p. 63, pi. iii. fig. 12 ; and Busk has described Cellepora am - 
pidlacea from Madeira, which has a round aperture. 
Rhynchozoon bispinosa var. 
There are two or three specimens of a Rhynchozoon with very 
numerous small papilliform avicularia scattered over the surface. 
The opening under the mandible is slit-like and much smaller than 
the mandible, and the avicularia resemble those of R. crenulata 
Waters, and it may be this species, but 1 hesitate to unite 
them from the specimens which I have examined. Round the 
border of the zooecia there is a row of large pores. The ovicell is 
entirely immersed, with an area placed vertically. The operculum is 
similar to that of R. bispinosa , and there are only very minute lateral 
teeth, whereas in R. crenulata the pronounced lateral teeth give the 
aperture a Lepralia-like appearance. 
Rhynchozoon bispinosa ( J olmst.) . 
One specimen has a few elevated avicularia with acute triangular 
mandibles, without a complete bar to the avicularium. The border of 
the aperture is slightly crenulated. 
Smittia ( Porella ) minuta Nonnan var. punctata nov. 
Two small specimens, in size resembling the Porella minuta of 
Norman, differ in having the surface of the zooecia and of the ovicells
