The large projecting spicules of the calicles are fusiform, usually more 

 less bent, and either acute at both ends or acute at the distal end and obtiiM- 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. With these, below the margin and in the polyps, there 

 arc many smaller and more slender, partly fusiform, partly oblong or rod-like 

 spicules, with both ends similar, and either acute or obtuse. 



The spicules of the ccenenchyma 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 PL XVI, figs. 1-lb.) 



Most 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 U.S. Fish Commission, 1878 to 1881, by the Gloucester, 

 Mass., halibut fishermen.

This abundant species grows in much branched bush-like 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 when expanded are paler and transluscent. 



Axis white with orange-brown nodes. Base much branched with flat 

 divisions. Stems rather stout; branches arise at nearly right angles to the stalk, 

 mostly in whorls of four, from the horn-like nodes; distal. ones slender, more 

 upright.
