Epizoanthus abyssorum Verrill. 1885. Fig. 27. 
B. range, 1,555 to 2,033 fathoms, 1883. Common. 
This species generally forms the carcinecia of Parapagurus pilosi- 
manus, but sometimes consists of two or three large obeconie polyps 
arising from a grain of sand. In the former case there are four to six 
divergent marginal polyps, usually with an odd one above and beneath. 
The polyps are large, usually clavate in contraction, with twenty-four 
convergent ridges at the summit. The surface is closely covered with 
small foraminifera, mixed with some sand grains. Color grayish white, 
purple or orange tinted at summit. Length of largest polyps, in con- 
traction, 10 to 13™™; diameter, 9 to 11™™.
