mens to which ho referred hnving been collected in the Red Sea and named by Dr. 

 Eduard Ruppel. 



In 1849 Prof. Johannes Muller, under Comatula (Aledo) palmata, listed speci- 

 mens in the Berlin Museum that had been collected in the Red Sea by Friedrich 

 Wilhelm Hemprich and Christian Gottfried Ehronberg, and others in the Paris Mu- 

 seum collected by Paul Emile Botta in 1S36. None of those specimens had been men- 

 tioned in the original description of Aledo palmata published in 1841. 



Felix Dujardin and H. Hupe* in 1862 gave a list of unpublished museum names 

 that the latter had found with specimens iu the Paris Museum. Among these names 

 was Comatula scita, which had been applied to this species. 



In 1869 Prof. Eduard von Martens mentioned this form, as Comatula palmata, 

 from the Red Sea. 



Prof. Ludwig von Graff in 1877 described the myzostomes from a specimen from 

 the Red Sea, which he listed as ? Comatula multiradiata, repeating this record in 1884. 



In 1879 Dr. P. H. Carpenter identified M tiller's palmata as a species of the genus 

 Antedon as he understood it and compared the structure of its division series with 

 that <>f the division series of other comatulids. 



In October 1882, Prof. F. Jeffrey Bell published a specific formula for Antedon 

 palmata, which was emended by Carpenter in March of the year following. 



The Antedon palmata of Carpenter's report on the comatulids of the Challenger 

 expedition published in 18S8 was for the most part the present species, but in the list 

 of principal localities Carpenter included both the Red Sea and Ceylon, showing that 

 he confused this species with the preceding as Muller had done in 1849. He said that 

 there are always two and sometimes three axillaries beyond the IBr axillaries. In the 

 key to the species of the Palmata group palmata was paired with gyges; the former was 

 said to have not over 25 cirrus segments and Pj much smaller than P 2 , while gyges 

 was said to have over 30 cirrus segments, Pi not much larger (that is, smaller) than P 2 , 

 and the lower brachials with flattened sides. Carpenter said that palmata is common 

 at Aden and in the Red Sea. There is no other mention of its occurrence at Aden, 

 and no specimens have ever been definitely recorded from that city. 



In his memoir on the comatulids of the Indian Archipelago published in 1891, 

 Dr. Clemens Hartlaub described hi detail under the name Antedon palmata five speci- 

 mens hi the Berlin Museum that had been brought from the Red Sea by Hemprich 

 and Ehrenberg and previously recorded by Muller in 1S49. He called these the type 

 ("original") specimens in spite of the fact that the specimen (or specimens) mentioned 

 in the original description had been brought by Dr. D. F. Eschricht from "Indien." 

 In addition to these specimens he gave notes on two in the Berlin Museum that had 

 been labeled Antedon spec, by Carpenter, another in the same museum from the Red 

 Sea, and one from Djeddah (Jiddah) in the Leyden Museum. Two of the specimens 

 in tlic Senckenberg Museum at Frankfurt-am-Maui that had been collected by Ruppel 

 and by him labeled Antedon leucomelas had been sent to Hartlaub for study, and one 

 of these he figured. The other specimens he mentioned — from Singapore, the Tonga 

 Islands, and Ceylon — are L. palmata palmata. Hartlaub described as a new species 

 Antedon klunzingeri, which was based on a single specimen from Koseir (Kosseir), 

 on the Red Sea coast of Egypt. In his key to the species of the Palmata group, 

 klunzingeri was paired with the very different (Cenometra) bella, and in the description
