DEVELOPMENT OF ANTEDON (COMATULA, LAMK.) EOSACEUS, 697 



Mediisce"^; whilst the second is adopted by Meckel S Heusinger^ Sabs*, Dujardin', 

 and Professor JoH. Muller in his memoir " Ueber die Gattung Coniatula und ihre 

 Arten"^ Professor Wyville Thomson regards the Comatula fimbriafa of J. S. MILLER^ 

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

 tical with the Antedon Millen 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. rosaceits which is characterized by the presence of interradial plates. I am disposed 

 to identify our Antedon rosaceus Avith the Comatula adeonw of Delle Chiaje^ But 

 it must not be confounded either with tJie Comatula fimhriata or with the C. adeoncp 

 of Lamarck, Joh. Muller, and Dujardin, or with the C. rosea of Joii. Muller and 

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

 Von Duben" and Koren. 



8. The synonymy of our Antedon rosaceiis, therefore, I consider to be as foUoAvs : — 



Stella decacnemos rosacea, LmcK. 

 % Stella decacnemos harbata, Linck. 



Asterias bifida. Pennant. 



Asterias decacnemos. Pennant. 



Asterias pectinata, Adams. 



Alecto Europcea, Leach, followed by Joh. Muller. 



Comatula Mediterranean Lamarck, followed by Meckel, Heusinger, Sars, Dujardin, 

 and Joh. Muller. 



% Comatula barbata, Lamarck, followed by Fleming. 

 ■? Comatula fimbriata, J. S. Miller. 



Comatula rosacea, Fleming, Blainville, and Edward Forbes. 



Comatula decacnemos, J. V. Thompson. 

 1 Comatula adeonce, Delle Chiaje. 

 1 Comatula Milleri, Joii. Muller. 



Alecto petasus. Von Duben and Koren. 



Antedon decameros. Gray. 



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

 verer, Mr. J. V. Thompson, the designation Pentacrinus Europwus, and from Blainville 

 that of Phjtocrinus Europceus ; whilst Fleming proposed for it the designation Hibemula.
