Polyclinum globosiim, new species. General character of the colony.— Massive, inclined toward the spherical form, attached by a small area only; apparently easily detached, since all the specimens at hand are freed from their original substrata. (Fig. 14.) Dimensions of largest colony: least transverse diameter, 35 mm. The other colonies considerably. /r >"'.£:;: Length, 45 mm. smaller. Color, greenish brown. Zooids.—Large and numerous, though scarcely visible on the surface of the preserved colonies. The irregular systems contain numerous zooids, many of which are quite distant from the broad but inconspicuous atrial orifice common to the system. Positions approximately perpendicular to the surface of the colony. (Pig. 14 Z.) Body distinctly separated into three regions, viz, thorax, abdomen, and postabdomen. (Fig. 15.) Measurements of the zooids: Total length, 10 mm.; length of thorax, 4 mm.; length of postabdomen and abdomen, 6 mm. Test.—Small in quantity among the zooids, so close are these to one another; but a considerable mass in the middle of the colony in which no zooids occur. (Fig. 14.) Surface layer considerably denser and darker in color than the deeper portions, a few scattered sand grains embedded on the sur- face. The inner mass containing no zooids, rather firm in character; opaque white, contains many small cells
