A MONOGRAPH OF THE EXISTING CRINOIDS 339 



original Lamarckian types in Paris, and in a paper on the crinoids of Africa I suggested 

 that the Comatula Solaris recorded by von Martens from Zanzibar was probably 

 Tropiometra carinata. 



In 1912 Hartlaub recorded a fragmentary specimen of Actinometra echinoptera 

 var. meridionalis from Hong Kong. Most likely it was in reality this species, though 

 it may have been C. pectinata; it certainly could not have been any form of Comadlnia. 

 In 1912 I gave a detailed account of this species in connection with a survey of the 

 crinoids of the Indian Ocean, and in a paper on the crinoids of the Hamburg Museum 

 gave notes on a specimen from Singapore, recorded one from Rockhampton, Queens- 

 land, and mentioned the two which had been described in detail by Carpenter in 

 1882 as Solaris and robusta. 



In 1913 I listed all the specimens in the collection of the British Museum, rede- 

 termining the material from the Alert dredgings described by Professor Bell in 1884. 



In 1914 Dr. H. L. Clark mentioned a specimen from the coast of Western 

 Australia. 



In the report on the unstalked crinoids collected by the Siboga (1918) I published 

 a key to the species of Comatula in which a distinction was made between the stout- 

 armed type of Solaris and the slender-armed type which was designated as variety 

 hamata. 



In 1921 Dr. H. L. Clark discussed the distribution of this species in great detail, 

 and in 1923 he recorded additional specimens from localities in the Abrolhos Islands, 

 Western Australia. 



In 1924 Dr. Torsten Gisle"n brought out some additional information in regard to 

 the skeletal structure of this species.
