I added that the specimen of Antedon monacantha from Torres Strait recorded by 

 Hartlaub appears to be nearer S. indica than S. monacantha. In another paper 

 published in the same year I compared the pinnules of Stephanometra monacantha 

 with those of Oligometra marginata, sp. nov. 



In my memoir on the crinoids of the Indian Ocean published in 1912 I gave a 

 complete synonymy of this species, including under Stephanometra monacantha 

 Liitken's Antedon protectus (in part), the Antedon palmata recorded from Tuticorin 

 by Bell and Thurston, Antedon militaris Hartlaub, MS., Antedon spicata Brit. Mus., 

 MS., Antedon monacantha Hartlaub, Antedon flavomaculata Bell, and Himerometra 

 acuta A. H. Clark. I referred Himerometra heliaster A. H. Clark to the genus 

 Dichrometra. Specimens collected by the Investigator were recorded from off north- 

 eastern Ceylon, the Andaman Islands, and Port Blair, Andaman Islands. A complete 

 list of all localities was given. 



In 1913 Dr. August Reichensperger recorded and gave notes upon a specimen 

 from Ceylon. 



In a paper on the crinoids of the British Museum published in 1913, notes were 

 given on the type specimen of Bell's Antedon flavomaculata, which was referred to 

 Stephanometra monacantha. The specimens from Tuticorin recorded as Antedon 

 palmata by Bell and Thurston, one from Hulule, Maldives, recorded by Bell as 

 Actinometra maculata, the specimen from Male, Maldives, labeled Antedon Ispicata, 

 and another from Muhlos, Maldives, were recorded as Stephanometra indica. 



In 1915 Dr. Hubert Lyman Clark recorded this species from Mer Island in Torres 

 Strait, and in another paper he mentioned its occurrence in Ceylon. 



In my report upon the unstalked crinoids of the Siboga expedition published in 

 1918, 1 recorded specimens of Stephanometra monacantha from stations 89, 96, and 250. 

 A synonymy of the species was given, and the range was said to be from the Andaman 

 Islands to Singapore, the Philippines, the Malay Archipelago, New Caledonia, Fiji, 

 and the Tonga and Caroline Islands. Under the name of Stephanometra indica 

 another specimen was recorded from station 301 that was said to agree with specimens 

 of indica from Ceylon. Dr. H. L. Clark's specimen from Torres Strait was also 

 referred to indica. The range of S. indica was given as Madagascar, the Seychelles, 

 and Rodriguez to Ceylon and southern India, Lesser Sunda Islands, and northern 

 Australia. 



In 1921 Dr. Hubert Lyman Clark noted that I had referred his specimen from 

 Torres Strait to indica rather than to monacantha. He said that he had reexamined 

 the specimen in the light of my key to the species of Stephanometra and compared it 

 with what seem to be unquestionable examples of monacantha from the Philippines 

 and from Tutuila, Samoa, and he saw no reason to change his original identification, 

 granting, of course, that monacantha and indica are really distinct. He remarked 

 that after I examined the specimen (M. C. Z., 599) I was satisfied that it really is 

 monacantha. In a footnote he said that I had recorded indica from Torres Strait in 

 1918 (that is, in the Siboga report), and he had therefore included it in his tabulated 

 list of Torres Strait echinoderms. He said that as he knew nothing of the specimen 

 upon which the record rests, but believed it to be his specimen of either callipecha or 

 monacantha, he had not included it in the mam body of his memoir. The specimen
