few surviving Pennatulid:e may have been derived. But owing 
to the difficulty of determining satisfactorily animals of this 
family from alcoholic specimens, we shall notice only a few spe- 
cies which have been figured from life by Verrill. 
Sagartia abyssicola (Fig. 460) is often found attached to the 
tubes of Hyalinecia. A large red or 
orange species of Actinauge is I. 
nodosa (Fig. 461), the column of 
which is covered with hard warts ar- 
anged in rather regular transverse 
and vertical rows, diminishing in size

in diameter and six inches in height 
are often brought up in the dredge. 
It has been dredged off our eastern 
coast, and extends from the Grand 
Banks to Cape Hatteras. Its bathy- 
metrical range is from 50 to 600 = — : i 
fathoms. From the tentacles and “S "^ p) eim 
upper part of the column is secreted 
an abundant mucus, which is highly phosphorescent. As has 
been suggested by Verrill, these Actinie, anchored as they are 
in the mud by a basal bulb, probably lose their power of loco-
