Scientific expeditions. 44 G Canadian Arctic Expedition, 1913—WIS The large pi-ojecting spicules of the calicles are fusiform, usually more or less bent, and either acute at both ends or acute at the distal end and obtuse at the other. The larger of these measure 4-40 by 0-35, 4-10 by 0-30, 3-80 by 0 • 30, 3 • 70 by 0 • 22 mm.

The larger of these measure 4-40 by 0-35, 4-10 by 0-30, 3-80 by 0 • 30, 3 • 70 by 0 • 22 mm. With these, below the margin and in the polyps, there are many smaller and more slender, partly fusiform, partly oblong or rod-Uke spicules, with both ends similar, and either acute or obtuse. The spicules of the coenenchyma are large, fusiform, and striated, mostly acute at both ends, and bear small conical spinules in rows. The larger ones measure about 4-2 mm. long by -025 thick, but most are smaller, about 2-5 to 3-5 mm. long by -015 to -020 mm. thick. One specimen, lacking the base, was about 40 inches high (1020 mm.) and one of its branches was 27 inches, or 675 mm., long before dividing. One of the type specimens was 660 mm. high. (See PI. XVI, figs. 1-lb.) ]\Iost of the known specimens came up entangled by the lines used in deep water fishing, in about 200 to 300 fathoms, around the Banks off Nova Scotia, and were presented to the Fish Commission, 1878 to 1881, by the Gloucester, Mass., halibut fishermen.

This abundant species grows in much branched bush-hke forms about eight inches to a foot high and often nearly as broad. The colour, when living, is usually light chestnut-brown, varying to orange-brown and dark brown; polyps
