REMARK

To accommodate the Lamarckian species Asterias ocellifera, Gray (1840) established the genus Nectria . Yet Gray had not seen Lamarck’s type specimens of A. ocellifera . When working on asteroids of the genus Nectria housed in the British Museum, Perrier (1875) realised that the species N. ocellifera sensu Gray was different from the species described by Lamarck while sharing some similarities with the second Paris specimen also identified as A. ocellifera by Lamarck. He consequently proposed the new name Nectria ocellat a for Gray’s specimens and gave a precise description of one of the Gray’s individuals that will be considered later as the lectotype of the species ( Zeidler & Rowe 1986). As a consequence, the second specimen of Lamarck, while collected by Péron and Lesueur and being representative of the Perrier’s species, is not a type of Nectria ocellata Perrier, 1875 .
