274 THE VOYAGE OF H.M.S. CHALLENGER. 



The colour of the spirit specimen is brownish. 



This species is very nearly related to Si/mjJodimn abyssoru.m,Da.niehiien. The tendency 

 of both species to form independent coenenchyma stocks, brings them near to the 

 Alcyonidse to which they lead up. A similar structure occurs exceptionally in Sympodium 

 coralloides, Pall. 



Habitat. — Nightingale Island; depth. 100 to 150 fathoms.
