Padaw, Mergui Archipelago [A. H. Clark, 1912] (1, I. M.). 



Geographical range. — From the Philippines and the Pelew Islands southward to 

 New Caledonia and the Kei Islands, and westward to the Andaman Islands and the 

 Mergui Archipelago. 



Bathymetrical range. — From the shore line down to 73 meters. 



History. — The first mention of this species is found in the Catalogue of the 

 Godeffroy Museum at Hamburg published in 1879, which includes the name Antedon 

 polypus Liitken without any indication of the form to which it refers. 



The species was next mentioned in 1887 as Antedon sp. by Prof. F. Jeffrey Bell in 

 a paper on a collection of echinoderms from the Andaman Islands made by Col. 

 Thomas Cadell, V. C, who at the time was in charge of the islands. Professor Bell 

 said that this Antedon was represented also in the collection made in the Mergui Archi- 

 pelago by Dr. John Anderson and that Dr. Herbert Carpenter had promised to discuss 

 its relations to A. palmata in the report on the crinoids of Mergui which he had in 

 preparation. 



In a list of the echinoderms of the Bay of Bengal published in 1888 Professor Bell 

 in a footnote said that Antedon andersoni (nomen nudum) had been collected by Dr. 

 Anderson at Mergui. 



In the Challenger report on the comatulids published in 1888 Dr. P. H. Carpenter 

 said that he had found the same extensive platuig on the disk characteristic of Antedon 

 (Zygometra) elegans in another species from Mergui which has a syzygy between the 

 elements of the IBr series and the postradial series dividing four times, each division
