DE^TILOPMENT OF ANTEDON (COMATULA, LAMK.) EOSACEUS. G97 



Mednsa;"^; whilst the second is adopted by Meckkl", Heusixger', Saks^ Dujardin^ 

 and Professor Jon. Muller in his memoir " Ueber die Gattung Comatula und ihrc 

 Arten"". Professor Wyville T!IO^rsoN regards the Comatula fmhriata of J. S. Miller', 

 which is described under the name C. Millen by Prof. Jou. Muller, as probably iden- 

 tical with the Anfedon Milleri of which I have already cited his definition (^ 6, note) ; 

 Miller's figure and description of it, however, seem to me scarcely sufficient to remove 

 the doubt suggested by its locality (§ 39) whether it is anything else than the variety of 

 A. roxacens which is characterized by the presence of interradial plates. I am disposed 

 to identify our Anfedon rosaceus with the Comatula adeome of Delle CHIAJE^ But 

 it must not be confounded cither ^^•ith the Covudula fimhnata or Anth the C. adeomv 

 of L.\MARCK, Joii. Muller, and Dujardix, or witli the C. rosea of Jon. Mijller and 

 DuJARDiN, which are distinct types. It is probably identical Avith the Alecto petasus of 

 Von DiJBEX* and Korex. 



8. The synonymy of our Antedon rosaceus, therefore, I consider to be as follo\vs : — 



Stella decacnemos rosacea, Linck. 

 ■? Stella decacnemos larhata, Linck. 



Asterias lifida, Pexxaxt. 



Asterias decacnemos. Pennant. 



Asterias jyertinata, Adams. 



Alecto Europcpa, Leach, followed by Jon. Muller. 



Comatula Mediterranea, L.uiarck, followed by Meckel, Heusinger, Sars, Dujardin, 

 and JoH. Mu^ller. 



% Comatula harhata, Laslarck, followed by Fleming. 

 % Comatula fimhriat a, J. S. Miller. 



Comatula rosacea, Fleming, Blaintille, and Edward Forbes. 



Comatula decacnemos, J. V. THOiiPSON. 

 % Comatula adeonw, Delle Chiaje. 

 1 Comatula Milleri, JoH. Muller. 



Alecto petasus. Von Duben and Koren. 



Antedmi decameros. Gray. 



The young pedunculate form of Anfedon rosaceus, moreover, received from its disco- 

 verer, Mr. J. V. Thompson, the designation Penfacrinus Europmis, and from Blainville 

 that of Plujtocrinus E^iropa^us ; whilst Fleming proposed for it the designation Hihernula.
