an inch ; the surface is rough with the long stout spinous processes ; it is 
brittle, light, and usually of a white colour. 
EXTINCT SPECIES. 
1. C. Urii. — Branched, round, about a quarter of an inch in diameter, 
form round — Millepore, Ure, Ruth. 228, t. xx. f. 1. 
Gen. LIII. BERENICEA. —Cells united in a spot-like crust, 
adhering throughout, and not circumscribed ; mouth at 
the distal extremity of the cells. 
132. B. coccinea . — Cells subcylindrical, adjacent, in diverg- 
ingly bifid rows ; mouth wide, a single blunt tooth on the outer 
margin, and two or three spines on the inner. 
Cellepora coc. Mull. Zool. t. clxvi. f. 1, 2.— Discopora bispinosa, John- 
ston^ Edin. Phil. Journ. xiii. 222. — On the under side of stones near 
low water-mark. 
Occurring in circular patches upwards of an inch ; towards the centre it 
is commonly rough with the ovaria ; the surface of the cells looks as if frosted, 
though glossy. 
133. B. hyalina. — Diaphanous, the cells forming an even, 
smooth crust, with tubular simple mouths. 
Cellepora hyal. Linn. Syst. i. 1286.— On stones, shells, and corallines 
from deep water. 
The crust is semitransparent, the divisions of the narrow cells indicated by 
whitish lines, and the orifices are narrow, cylindrical, simple tubes. The 
crust is not circumscribed, otherwise it resembles the genus Discopora. 
134. B. immersoj . — Cells forming an even, rough crust ; the 
mouths declining, small, with a blunt tooth on the proximal 
margin. 
On shells and corallines from deep water. 
Crust rather thick, of a brownish colour ; the divisions of the cells indis- 
tinct, the cells themselves being only a little elevated towards the aperture ; 
the whole surface minutely granular. 
135. B. utriculata.—Ce\h bladder-shaped, sitting, aperture 
with five or six teeth, the proximal one the largest. 
On stones and shells from deep water. 
The cells appear as unconnected, though adjacent, raised, rounded, the 
mouth scarcely terminal, restricted, contracted, and slightly prominent. 
136. B. nitida . — Cells subcylindrical, prominent, and trans- 
versely ridged. 
Cellepora nit. Fah. Faun. Gr. 435.— On shells, rare. 
Cells contiguous, the mouth terminal, transverse, simple. 
EXTINCT SPECIES. 
1. B. diluviana Cells pyriform, openings large — Lamour. Zooph. 8L 
t. Ixxx. £ 1. Geol. of Eng. 214 — -In Oolite.
