This Millepore is often Found incrufting many of the
Sertularias in fmall irregular maffes; when they are
thrown on fhore, the points of their cells are worn
off.
I have lately received a fpecimen from Aberdeen, with
compleat cells, that feems to be of this fpecies. It has
fmall cylindrical branches, each about hall an inch long;
the.cells are placed round about in an alternate order ;
they are Ihaped like a helmet or head-piece juft opening,
with a hole in the middle ; the under part is pointed, and
projects like the lower part of a bird’s beak ; and at the
bottom of each of the cells is a hole, which feems to belong
to one of the cells that is covered by the laft feries.
