History. Prof. Johannes Muller in 1841 described Alecto flagellata from a speci- 

 men without locality collected by Brugmans in the Leyden Museum that he found 

 bearing the manuscript name Comatula flagellata. At the same time he described 

 Alecto elongata from another specimen in the same museum that had been collected in 

 New Guinea by Salomon Muller and bore the manuscript name Comatula elongata. 

 He mentioned Alecto flagellata and A. elongata in 1843, and hi 1849 he redescribed them 

 under the names Comatula flagellata and C. elongata. 



Dujardin and Hup6 in 1862 published translations of Muller's original descrip- 

 tions of Comatula elongata and C. flagellata. 



Dr. P. H. Carpenter in 1879 was unable to refer either Comatula elongata or C. 

 flagellata definitely to Actinometra or to Antedon, as he had not seen them and knew 

 of no descriptions from which it is possible to obtain any information as to the position 

 of the mouth or the character of the oral pinnules.
