A MONOGRAPH OF THE EXISTING CRINOIDS 111 



"Port Jackson," and gave its essential characters. For the reasons given above 

 (p. 108) I do not now believe that this specimen really came from Port Jackson. 



In 1912 in an account of the comatulids in the Hamburg Museum I mentioned 

 the two examples of this species from Samoa and Fiji. These were two of the three 

 previously (1891) noticed by Hartlaub. Presumably the third had been sent to the 

 Gottingen Museum. I also gave the chief characters of another specimen which bore 

 a label in Chinese characters reading simply "very deep water." This may or may 

 not have come from somewhere on the coast of China. 



In my memoir on the crinoids of the Indian Ocean (1912) Adinometra notata 

 and Aniedon bassett-smithi were included in the synonymy of this species, as was 

 also the Adinometra maculata recorded from the Macclesfield Bank by Bell in 1894. 

 Previously unrecorded specimens from Padaw in the Mergui archipelago and from 

 ?India were listed and their characters given. 



In an account of the comatulids in the Berlin Museum pubhshed in 1912 this 

 species was recorded from New Guinea, and the characters of the single specimen 

 were given. 



In the memoirs on the recent crinoids of Australia (1911) and on the crinoids 

 of the Indian Ocean (1912) there were incorporated synonymical notes which I had 

 made as a result of an examination of the collection of the British Museum in 1910. 

 In 1913 I published a detailed account of this collection. Antedon bassett-smithi was 

 proved to be a synonym of Adinometra stelligera, and the specimens which Professor 

 Bell had recorded from the Macclesfield Bank under the names Adinometra maculata 

 and Adinometra simplex were also found to belong to this species. The eight lots of 

 specimens examined were listed, and the chief characters of the more interesting 

 specimens were given. 



In 1913 Dr. August Reichensperger recorded a specimen which has been collected 

 by Doctor Sarasin in Ceylon in 1886 and noted its essential characters. 



In 1915 Dr. Hubert Lyman Clark, who had visited Mer in September and 

 October, 1913, when he was a member of the Carnegie expedition to that region, 

 recorded this species as very common there, and published various notes on its 

 color in life, its habits, and its reactions. 



In 1918 I recorded it from four localities in which it had been found by the 

 Siboga expedition and published a colored figure drawn from a specimen of which *a 

 detailed color sketch of one arm had been made immediately after capture. 



Dr. Hubert Lyman Clark in 1921 published a detailed account of this species, 

 especially as it occurs on the Australian coasts, based upon his experiences with it at 

 Mer and accompanied by a colored figure. 



It was in this account of the species that doubt was first expressed concerning 

 the occurrence of this species at Port Jackson, New South Wales, whence I had 

 recorded it 10 years previously. 



Dr. Torsten Gislen in 1922, in his account of the crinoids collected by Dr. Sixten 

 Bock in 1914, recorded this form from three stations in the Bonin Islands, and gave 

 elaborate notes on the specimens. 



Dr. Hubert Lyman Clark listed a specimen from Wooded Isle in the Abrolhos 

 Islands (Houtman's rocks), Western Australia, m 1923, and gave its essential char-
