Occurrence. Professor Studer said that at Turtle Bay, Dirk Hartog Island, this 

 species was found clinging to seaweed. It was noted by Mr. Alexander as "very 

 abundant" off Geraldton. 



History. This species was first described in 1846 by Prof. Johannes Muller from 

 four specimens in the Paris Museum that had been collected by Quoy and Gaimard 

 in 1829 at King George's Sound, southwestern Australia, during the expedition of the 

 Astrolabe under the command of J. Dumont d'Urville (1826-29). With these speci- 

 mens Muller found the manuscript name Comatula macronema that had been given 

 them by Valenciennes, under which he described them.
