Bryozoa of the Bay of Naples. 
I have pieces ramose and tapering in the characteristic way 
of Busk’s coronopuSj and another incrusting with similar 
cells. 
Opercula suborbicular, slightly triangular at the proximal- 
end, T4 millim. wide, ‘156 long. 
Loc. Pliocene: Crag, Castrocaro, Sicily, and Calabria; 
Ficarazzi, Bruccoli, Rhodes, Antwerp ( H.cleL .). Living: 
Britain and coasts of France ( B .) ; Naples, 20-fathoms. 
The ramose form figured by Marsigli is common in the Medi¬ 
terranean.

Cellepora ramulosa, forma avicularis, Smitt, Ivrit. Fort. o. Sk. Hafs-B. 
18G7, pp. 32 and 194, pi. xxvii. figs. 202, 210. 
Zooecia raised, prominent; aperture suborbicular, with one 
or two raised avicularia usually turned inwards over the 
mouth, numerous large zooecial avicularia (scattered among 
the cells) with wide mandible rounded at the end. Ovicells 
raised, prominent, perforated. 
It grows incrusting large seaweeds, and forms rather large 
masses. The avicularia are much more raised than I have 
been able to show in my drawing. 
Op ercula (12*) suborbicular, the proximal end being the 
segment of a smaller circle than the distal end. Width 0T52 
millim., length 0T36, muscular dots 0'08 millim. apart. 
Hah. Britain, Arctic Ocean, Red Sea; Naples, 10 fathoms. 
63. Cellepora verruculata , Smitt. (PI. XIY. figs. ], 7.) 
Cellepora verruculata, Smitt, Floridan Bryozoa, Ivongl. Svenska Vet.-Ak. 
Handl. vol. xi. pt. ii. p. 50, pi. viii. figs. 170-172. 
The process (sometimes an avicularium) projecting as a 
tooth into the peristome is most marked in my specimens, 
and sometimes gives a triangular appearance to the aperture. 
The ovicells are smooth and imperforate; zooecia perforated 
round the edge, often with a large acute avicularium on 
ventricose avicularian chambers situated in the proximal part 
of the cell. 
The young cells are granulated, with the oral avicularia at 
one side, but when a little older have an ascending process 
on each side of the orifice, and often an umbo in the centre— 
in this stage exactly resembling Lepralia hieorms, Busk ; and 
it may be the same; but as I have not seen the fossil species, 
I cannot express an opinion.
