A MONOGRAPH OF THE EXISTING CKINOIDS 631 



I placed Dr. H. L.Clark's Comanthus anrmlatum xanthum in the synonymy of Coman- 

 thus {Vania) annulata, and his Comanthus callifeplumin the synonymy of Comantheria 

 briareus. No reasons for this disposition of these forms were given at the time, since 

 Doctor Clark's paper only reached me when the maiuisciipt was completed and about 

 to be sent to Holland. 



In 1921 Dr. H. L. Clark published his final account of the comatvdids which he 

 had collected and studied at Mer. He took vigorous exception to the placing of his 

 Comanthus callipeplum in the synonymy of Comantheria briareus. Since the publi- 

 cation of the Siboga report I had examined the t.vpe and only specimen of Comanthus 

 callipeplum and had been unable to find any characters by which it could be dis- 

 tinguished from C. timorensis (annulata). But he remarked that he could not 

 possibly concur in this conclusion. 



In 1922 Dr. Torsten Gisl6n recorded and described a specimen which had been 

 collected in the Bonin Islands by Dr. S. Bock, and mentioned certain features pre- 

 sented by a specimen from Java. 



In June, 1923, Dr. H. L. Clark described 7 specimens from Wooded Isle in the 

 Abrolhos Islands. In 1926 he recorded a specimen from Surprise Shoal, on the outer 

 Great Barrier Reef, and in a paper supplementary to his and published at the same 

 time Frank A. McNeill and A. A. Livingstone recorded a specimen from off Ellison 

 Reef, both of these specimens having been collected by Mr. W. E. J. Paradice.
