Smittia (subgenus Watersipora) cucullata, Neviani, “ Brioz. foss. della Farnesina e Monte 
Mario,” Paleont. Italica, vol. i. p. 120 (1895) ; “ Brioz. Neog. delle Calabria,” op. ezt. vol. vi- 
p. 209 (1900). 
There is considerable variation in the peristome, so that both in the Medi- 
terranean and in the Atlantic the var. labiosa, so named independently by 
both Hincks and Calvet, is found, as well as the type. 
Some of the Red Sea specimens have quite thin shells, whereas in those I 
have seen from Naples, Trieste, Rapallo, and Cape Verde the shell is thick, 
and in these the whole zoarium is very dark, whereas those from the Red 
Sea are much lighter; some are even without pigment, only the operculum 
being dark. 
The operculum is very characteristic and does not vary in any of the 
forms ; at the side there are the two lighter places in the very dark operculum, 
and the two small hollow knobs near the base are distinctly seen. These 
apparently act as stops when the operculum is open (figs. 2, 3), and then the 
operculum is bent back nearly at right angles. The ovaria grow at the side 
of the zocecium, but the ovum passes for development into a sac at the distal 
end by the basal wall (fig. 4). This ovicell is what I have called a concealed 
ovicell. 
There are about 23-24 tentacles, with two larger than the others. 
No oral glands were found in the young or the mature zocecia until the 
ovicell was forming; however, when the ovaria are becoming large, two 
bodies begin to grow from the fleshy mass on the operculum (fig. 10), and 
when the ova are in the ovicell these become moderate-sized glands. This 
misled me at first into believing that there were no glands, and possibly 
glands will be found in the fully mature zocecia of other species where they 
have not yet been seen. 
In specimens from Trieste there is a band of darkly pigmented cells all 
round the stomach. A band of dark cells is known to occur in other species, 
but I have never seen any so dark as these; although they have been called 
liver-cells, they should perhaps be termed pancreatic.
