A. E. Verrill-Radiata from the Coast of N. em•olina.433 of an inch apart, and generally not more than '5 to 1 inch long before dividing.The branches are rather stout, terete or subcompressed, usually but little crooked.The branchlets are terete, slender, but not elongated, rather rigid w hp.n dry, slightly tapering to the end.The axis is dark, dull wood-brown in the larger branches; translucent amber-yellow in the branchlets; light yellowish wood-color at the base.The polyp-cells are small and usually very little raised, arranged in four to Rix irregular alternating rows on the sides of the large branches, and in two to four rows on the smaller ones, leaving only a narrow naked median space, along which there is generally a distinct line corresponding to the large longitudinal ducts.Color of the comenchyma bright brick-red.Height 12 inches, breadth about the same; diameter of the larger branches, '15 to '20 of an inch; of the branch lets, '05 to '07.The spicula of the coonenchyma are light red, and consist of minute "double-spindles" of several degrees of stoutness, but mostly rather short, thick, and blunt.The largest and stoutest ones are '096 mm by '042, '096 by '036, '090 by '048; they have a very narrow naked median zone, and two close whorls and a terminal cluster of rough warts on each end; many other smaller and shorter ones have but one whorl and a terminal cluster of warts.'l'he most slender ones are small and acute at the ends, with a wide naked zone and with two or three more distinct whorls of few warts on each end; they measure '132 01m by '030, to '120 by '036.'l'here are also many forms of more minute spicula.The polyp-spicula are bright red, slightly spinulose, and vary in size from '096 mlli by '018 to '072 by '010.
