Definition. — Centro-dorsal usually somewhat hemispherical or conical, rarely discoidal, 

 and generally bearing at least twenty cirri, often several more, which leave but little of 

 its under surface free. Outer faces of the radials relatively high, with large muscle- 

 plates, and much inclined to the vertical axis of the calyx. 



Disk with a central or subcentral mouth and five equal ambulacra, which extend on 

 to all the arms. These are ten or more in number, all of the same length, and may have 

 an ambulacral skeleton which is most differentiated on the pinnules. Sacculi almost 

 always present on the pinnules, if not elsewhere. 



History. — This genus was established in 1811 by de Frdminville, 1 who was the 

 first to remove the Feather-stars from the confusion of the Linnean genus Asterias and to 

 give them a definite generic rank. A similar course was taken three years later by 

 Leach, who was probably unaware of de Freminville's work, and established the genus 

 Alecto for the Feather-stars ; but the same can hardly be said of Lamarck, who deliber- 

 ately rejected de Freminville's generic name, replacing it by one of his own making, viz., 

 Comatula, and he doubtfully referred de Freminville's species Antedon gorgonia to his own

 p. 349. In this note de Fr^minville referred to an illustration of Antedon in the Encyclop^die Methodique ; and 

 Perrier has consequently been led to mention the latter work as that in which the name Antedon was first proposed 

 Now. Archiv. Mus. Hist. Nat., t. ix., 1886, p. 79).
