A MONOGRAPH OF THE EXISTING CRINOIDS 125 



at the original Porcupine station. Carpenter thought it very probable that the com- 

 atulids obtained by the Talisman in depths of about 1,200 meters off the Azores and 

 Canaries, in 2,200 meters off Agadir, and in 2,330 meters near the Cape Verde Islands 

 may belong to the same deep sea type. He said that the former, however, might possibly 

 also include Antedon (Leptometra) phalangium "which is now known to extend down 

 to at least 500 fathoms." Carpenter called attention to the similarity in the arm divi- 

 sion between Antedon (Stiremetra) lusitanica and A. (Thalassometra) multvspma and 

 said that should IIBr 4(3 + 4) series prove to be common in these two species it may 

 become necessary to unite them under one name. At present, he said, the main points 

 of difference between them, apart from the characters of the arm divisions, appear to 

 lie in the longer cirri and less spinous arms of Imiianica, m which also the segments of 

 the genital pinnules, as the Madeira specimens show, are somewhat produced upward 

 on the outer side as is so markedly the case in Antedon (Chantometra) basicurva, but, 

 Ita «fiirl there is nothing of this kind in multispina. 



In a Purvey of to Basicurva group published in 1895 Dr. Clemens Hartlaub listed 

 Antedon lusitanica, giving the locality and depth, and » 1^ ^. Jamea^ £j*J* "Jj 

 mentioned it as a member of the Baskurva group. Dr. Wdhlem Minckeit in 1905 

 hsted it as one of the species of the Baskurva group falling also in the S^mfera and 



& tS Envision of the genus Antedon published in 1907 lusitanica was trans- 

 f erred to the new genus Thalassometra. In my revision of the family Thalassometridae 

 puDhshed in 1909 Antedon luzilanka was listed among the species I was unable to place 

 satisfactorily.^^ ^ ^^ ^^ numerous specimens f Antedon Imiianka
