Bryozoa of the Bay of Naples. 
shows a small specimen, and in larger ones there are about 
three times as many branches as are shown. 
The zooe'ciiim when seen from the front is coffin-shaped, 
witli the aperture at the top and a nearly circular opening 
below it {as in Lepralia violaceci). The operculum is semicircu¬ 
lar, with a straight proximal end and large muscular projec¬ 
tions on each side. The tube from each cell emerges from a 
small chamber (see fig. 11) at the top of the cell ; and in the 
lower wall of this chamber is apparently one rosette-plate. 
Hob. Red Sea and Mediterranean ( Aud .). 
I did not find Eucratea clielata at Naples; but it is reported 
to have been found in the Mediterranean. Eucratea has 
been described fossil as Unicrisia (tenerrima &c., in the 
Eocene) ; but a small-jointed species like the present would 
probably be overlooked even if it occurs.
