Dr. Clemens Hartlaub in 1891 recorded (as regalis) 17 specimens from Amboina 

 which had been collected by Dr. J. Brock. The specimen from Mortlock Island 

 which he recorded as parvicirra also proves to belong to this species. 



In 1894 Bell recorded a specimen, as Actinometra duplex, from the Macclesfield 

 Bank. In 1895 Prof. Rene Kochlcr recorded this species (as regalis) from the Sunda 

 Islands and in another paper also from Amboina, and in 1898 Prof. Ludwig Doderlein 

 again recorded it (as 7-egalis) from Amboina. 



In 1902 Bell recorded (as Actinometra typica) a specimen from the Maldives 

 which had been collected by Prof. J. Stanley Gardiner. 



In 1908 I recorded this species as Comanihvs nobilis from 6 localities in the Philip- 

 pines and as Comanthus duplex from another. In 1909 I listed it as C. nobilis from 4 

 more Philippine localities and as C. duplex from a fifth. In another paper published 

 in the same year I recorded it from Singapore. 



After an examination of the type of Carpenter's Actinometra schlegelii at Leyden 

 and of his duplex, nobilis, and regalis in the British Museum, I published in 1911 

 notes showing that the Leyden specimen had been misinterpreted on account of the 

 inaccuracy of the original description, and also notes on the type specimen of regalis, 

 calling attention to the fact that it also had been erroneously described, as is easily 

 seen by a comparison between the original description and the figure. Actinometra 

 dissimilis. Act. duplex, Actinometra nobilis, and Act. regalis were all shown to be syno- 

 nyms of the earlier Actinometra schlegelii. 



In another paper published in the same year I recorded and gave notes upon a 

 specimen without locality in the Paris Museum. 



In a monograph on the crinoids of Australia pubUshed in 1911 the synonymy 

 just indicated is included, and a complete account of the species, so far as the coasts 

 of Australia are concerned, is given. Bell's record of Actinometra multijida from the 

 Percy Islands is here corrected. 



In a monograph on the crinoids of the Indian Ocean published in 1912 the revised 

 synonymy is given, all of the records from the Indian Ocean are corrected on the 

 basis of a study of the specimens in the British Museum, and the species is recorded 

 from 3 new localities. 



In a paper on the crinoids of the Hamburg Museum published in 1912 I assigned 

 Hartlaub's specimen of parvicirra from Mortlock Island to this species, and also 

 recorded it from 2 additional localities. In another paper on the crinoids of the 

 Berlin Museum published in the same year I gave notes on one of the specimens 

 from Amboina collected by Brock which had already been described by Hartlaub. 

 In a paper on the crinoids of the Solomon Islands, also published in 1912, I recorded 

 this form from that region on the basis of a specimen collected by the Penguin which 

 I had seen in the British Museum. 



In 1913 I published notes on all the specimens of this species in the British 

 Museum, and in the same year Dr. August Reichensperger recorded it from the Aru 

 Islands and from Amboina, giving notes on his specimens. 



In 1915 Dr. H. L. Clark recorded 2 specimens from Ceylon and in another paper 

 mentioned 3 from Torres Strait. These last, however, are really belli. 



In 1918 I recorded this species from 6 additional locahties in the East Indies, 

 where it had been collected by the Siboga, and gave notes on the specimens.
