A MONOGRAPH OF THE EXISTING CRINOIDS 325 



1881 Carpenter said that through the kindness of Professor Mobius of Kiel he had been 

 enabled to examine specimens of Antedon carinata from Mauritius, which he said was 

 the origuial locality of Alullcr's type specimens that Prof. E. von Martens had courte- 

 ously permitted huii to study in the University Museum at Berlin. He said he had 

 also seen specimens from Madagascar and the Seychelles, and mentioned the dissected 

 calyx of a specimen from Zanzibar. He regarded specimens from Brazil, Chile, St. 

 Helena, the Red Sea, and Aden as specifically identical with carinata. He remarked 

 that Liitken had given the manuscript name Antedon brasiliensis to a 10-armed coma- 

 tulid that is abundant on the coast of Brazil. He noted that Pourtal^s and Rathbun 

 had considered this as a synonym of Lamarck's Comatula carinata and added tiiat 

 although he was at first inclined to follow Lutken in separating the two types further 

 study had led hun to believe in their specific identity. This conclusion was confinned 

 by the resemblance between the dissected calices of specimens from Bahia and from 

 Zanzibar. He said these are so very similar that if they were fossils he would unhesi- 

 tatuigly refer them to the same species. In fact, the Bahia spechnens vary consider- 

 ably among themselves, andj^there^is less^likeness between two calices from this 

 locality than there is between one of them and a calyx from Zanzibar. He said that 

 Antedon carinata is described by Rathbun as probably ranging along the Brazilian 

 coast to Pernambuco. It was not obtained by the Blake at all, but it was found in 

 abimdance by Captain Cole of the Investigator in 278 fathoms off St. Lucia, so that it 

 may fairly be considered as belonging to the Caribbean fauna. 



In a paper oa the comatulids of the Leyden Museum published in 1881 Carpenter 

 gave a synonymy oi Antedon carinata (Lamarck) in which he included, with a question 

 mark, de Fr^minville's Antedon gorgonia, Leach's Alecto carinata, and, without any 

 qualification, Liitken's Alecto braziliensis and Verrill's Antedon dtibenii. After the 

 name Alecto hraziliensis he wrote "Lutken, MS., 1865?," indicating that Lutken had 

 first used that name at about that time; but it was never published by him. In a 

 paper on the comatulids of the Hamburg Museum published in 1882 Carpenter said 

 that this museum contains two dry specimens of Antedon carinata from Mauritius 

 that are remarkable for the very slight carination of the dorsarsurface of the arms, and 

 remarked that had Lamarck's origmal specimens been like these he would assuredly 

 never have given them the specific name carinata. Two other specimens without 

 locality have as many as XXX cirri, a larger number than'is found on specimens from 

 Mauritius, while the pimiules are considerably stouter and more fleshy than in the 

 type, the lower ones especially having broader basal segments. These last may not 

 be true carinata. As carinata he also recorded four specimens from Java, which are 

 hereui considered as representing clarki (p. 285). 



In a memoir on the echinoderms collected by Prof. E. van Beneden on the coast 

 of Brazil published in 1882 Prof. Hubert Ludwig said that Antedon carinata is connnon 

 on the coast of Brazil. In the same year Prof. F. Jeffrey Bell proposed a specific 

 formula for Antedon carinata which was emended by Carpenter early in the year 

 followmg. 



In 1883 Carpenter said that he had found Antedon carinata much more favorable 

 for the study of the finer anatomical details than ..rl. bifida. The material with which 

 he worked came from Bahia.
