than 500 fm, but its known range is from 215 to 2369 fm. 



In the historical survey this species was most common on the 

 slope north of Baltimore Canyon between 1550 and 1800 m depth. It 

 was also found at 200 m north of Baltimore Canyon, between 1750 

 and 1900 m off Cape Hatteras and between 1300 and 1600 m in Heezen 

 and Corsair Canyons. In the field study several individuals of 

 K, stellifeTum were found in Lydonia Canyon between 700 and 800 m 

 depth.

This species forms long slender colonies on which the auto- 

 zooids are arranged bilaterally. Each lateral series consists 

 of transverse polyp rows extending around 1/4 to 1/2 the circum- 

 ference of the rachis. There are up to six autozooids in each 

 row and these are basally fused together and also covered by 

 a short leaf-like fold of tissue from the rachis. Within each 

 polyp leaf there is a fan-like group of ten of more elongate 

 (1.5 mm) needle-like spicules. Spicules, in the form of small 

 three-edged twisted rods (about 0.1 mm long), also occur in the 

 tentacles of the autozooids. In an expanded state the autozooids 

 and their tentacular crown are often very elongated. The 

 siphonozooids are minute and barely discernable. They occur on 

 the rachis between the polyp leaves.
