The Alcyonaria of East-Greenland. 503 



species has been found in depths from 122 to ca. 700 fathoms, but 

 apparently reaching its maximum — and really gigantic — develop- 

 ment in comparatively shallow water (i. e. 200—300 fthms.), where 

 the bottom temperature remains constantly below zero or oscillates 

 round the freezing point (as in the Umanakfjord). In depths sur- 

 passing 700 fthms. hitherto only quite young stages have been found.
