A MONOGRAPH OF THE EXISTING CRINOIDS 207 



In 1888 Prof. F. Jeffrey Bell listed Actinometra parvicirra as inhabiting the Bay 

 of Bengal, the record being based upon specimens sent to the British Museum by 

 Mr. Edgar Thurston, of the Madras Government Museum. Examination of the 

 material in London in 1910 showed that two of these specimens are in reality 

 multiradiata. 



In 1889 Prof. Th. Studer recorded this species from two localities in Western 

 Australia where it had been dredged by the German steamer Gazelle. 



Dr. Clemens Hartlaub in 1891 reviewed the Fimbriata group of Actinometra. 

 To it he assigned 8 species, 1 (discoidea) from the Caribbean islands, 1 (lineata) from 

 Brazil, and the other 6 from the Indian archipelago and the Cliina Sea. 



Under the name of Actinometra coppingeri he described a specimen which had 

 been collected by Prof. J. Brock at Amboina in 1884-85. To Actinometra Jimbriaia 

 he referred a very remarkable specimen from Ruk in the Carolines which he found 

 in the Hamburg Museum. As Actinometra multiradiata he recorded 5 specimens 

 from the China Sea in the Gottingen Museum, and another from Formosa (Taiwan) 

 which he found in the Hamburg Museum bearing the manuscript name Actinometra 

 gracilis of Liitken. As Actinometra multiradiata he also described a specimen from 

 Kagoshima, Japan, which is referable to mariae. 



In 1894 Mr. Edgar Thurston published a few notes on the occurrence and habits 

 of a few comatulids found in shallow water on the coast of the Madras Presidency in 

 India. His specimens had been identified by Bell, and on examining them in London 

 I found an example of this species among those determined as [Comanthus] parvicirra. 



Professor Bell in 1894 recorded this species (as multiradiata and as Jimbriata) 

 from northwestern Australia. He mentioned the chief localities where collections 

 had been made, but did not segregate the species according to locality. Prof. B.en6 

 Koehler in 1895 recorded multiradiata from Billiton where it had been collected by 

 M. Korotnev, Prof. Georg Pfeffer recorded it (as coppingeri and &s Jimbriata) from 

 Ternate in 1900, and in 1902 Professor Bell recorded it (us Jimbriata) from the Mal- 

 dives. In 1904 Mr. Herbert Clifton Chadwick recorded it from four stations about 

 Ceylon. 



In February, 1908, the present author in a revision of the comasterids referred 

 this species (as borneensis, coppingeri, Jimbriata, and multiradiata) to the genus 

 Comaster. In October, 1908, in a paper on the brachial homologies in the recent 

 crinoids he redefined Comaster on the basis of the characters exhibited by the arm 

 divisions and referred to it all the described forms now included, as species or as 

 synonyms, in the genus Capillaster. 



In December, 1908, the author recorded this species {as Jimbriata and as cop- 

 pingeri) from a number of localities in the Philippines where it had recently been 

 dredged by the United States Fisheries steamer Albatross. 



In April, 1909, the author published a note in which he showed that the generic 

 name Comaster is not available for the species of this general group, and for them he 

 therefore suggested Capillaster, with the genotpye Actinometra sentosa P. H. Car- 

 penter, 1888. 



In May, 1909, the author recorded the species from additional Albatross stations 

 in the Philippines and stated that "A critical study of a very large series shows that
