The septa are nearly straight, but slightly undulate all over;their surfaces are sparsely covered with minute-pointed granules. The columella ismade up of abundant, very stout, and unusually contorted fascicular outgrowths fromthe septa. The soft tissues of the living animal are of a dark madder colour. There areforty-eight tentacles disposed at the inner margins of the septa at successively greaterintervals from the mouth of the animal, as shown in the figure (PL XVI. fig. 12). Thetentacles are of four sizes corresponding with the septa. This species appears to come near Flabellum sinense, Milne-Edwards and Haime, ofwhich I have seen specimens in the Turin Museum, from Miocene deposits at Turin. Height of the largest specimen, 35 mm. Longer diameter of the calicle, 50 diameter, 40 mm. Station 232, off Enosima, Japan. 345 fathoms. About eight specimens. Flabellum alabastrum, Moseley (Proc. Eoy. Soc, 1876, p. 555). (PI. VII. figs. 1,1«, lb, 2, 2a, 2b; PI. XVI. fig. 11.). Flabellum alabastrum (Moseley). Slightly enlarged. The corallum is of a beautiful light-pink colour, and is very thin and is wedge-shaped, the calicle arising from an attenuated pedicle. The lateralcostse make an angle with one another of from 120° to 140°, and are sharp andmoderately prominent, with an irregular edge. The external surface of the calicleis covered with a glistening epitheca, which is whitish in colour towards the primary and secondary costse on the faces are almost as well marked as the (ZOOL.
