The figure is bluntly ovate, especially when young, dividing with age into 
short rounded lobes, varying from a reddish-orange to a greyish-white ; the 
pores are stellate and prominent ; the cells are inversely conical. The poly- 
pi, according to Ellis, when exserted, are conico-tubular, with 8 ridges ; these, 
I have observed to be armed near the summit, on each side, with a row of 
diverging spicula, like the particles composing the crust of the Gorgonia ver^ 
rucosa, Ellis, Cor. t. xxvii. No. i. A. 3. The tentacula are depressed, broadest 
at the base, and terminate in a point ; the pinnulse, are opposite at first, but
