B-24 



In the field study this sea pen was found in Oceanographer and 

 Lydonia Canyons between 1100 and 1800 m depth: With this species 

 it is impossible to positively identify specimens from photo- 

 graphs, thus the distribution reported in this study must be 

 considered tentative. 



KoTphohelemnon stelliferum (Miiller)

Species of Kophobelemnon characteristically develop into 

 cliib-shaped colonies 10-20 cm high. The authozooids are concen- 

 trated on the swollen upper 1/3 or 1/4 of the colony and are 

 scattered irregularly on all sides except for a medial polypless 

 lone down the center of one side. The large autozooids (3 mm 

 or more in diameter) are completely retractile; however, they can 

 be preserved with part of the anthocodia exposed. Some of the 

 polyps may be situated on calyx-like swellings of the rachis. 

 The minute siphonozooids are scattered irregularly on the rachis 

 and extend down the stem in somewhat longitudinal rows. Spicules 

 occur as slender, flattened or three-edged, twisted rods with 

 round ends and smooth or slightly nodose edges. They are up to 

 0.35 mm long and very abundant - giving the surface of the colony 

 a firm coarse texture. The color of preserved colonies is light 

 grey. The species is found in the Mediterranean, in the northeast 

 Atlantic, in the north Pacific and in the northwest Atlantic from 

 George's Bank to Virginia. It usually occurs at depths greater
