Sagartia abyssicola (Fig. 460) is often found attached to the tubes of Hyalinoecia. A large red or ^ orange species of Actinauge is A. nodosa (Fig. 461), the column of which is covered with hard warts ar- ranged in rather regular transverse and vertical rows, diminishing in size from the top of the column towards Fig-. (Verrill.) the base. Specimens of four inches in diameter and six inches in height are often brought up in the dredge. It has been dredo^ed off our eastern coast, and extends from the Grand Banks to Cape Hatteras. Its bathy- metrical rano-e is from 50 to 600 fathoms. From the tentacles and upper part of the column is secreted an abundant mucus, which is highly phosphorescent. As has been suggested by Verrill, these Actiniae, anchored as they are in the mud by a basal bulb, probably lose their power of loco-.
