Geographical range. — From the Macclesfield Bank and the Philippine Islands to 

 the l'elew and Caroline Islands, New Guinea, the Admiralty and Solomon Islands, 

 Fiji, the Loyalty Islands, and Torres Strait, westward to the Red Sea. 



Bathymetrical range. From the shore line down to 55 (?64) meters. Most of 

 the specimens have been taken in shore collecting. 



History. — This species was first described as Antedon sjricata by Dr. P. H. 

 Carpenter in 18S1 from a specimen in the Leyden Museum that had been collected 

 by Semmelink in the Banda Sea. In October 1882, Prof. Jeffrey Bell published a 

 specific formula for this form, which was emended by Carpenter in April, 1883. 



In 1885 Professor Bell recorded it from Ugi (or Ughi) in the. Solomon Islands, 

 and in 1888 he said that it had been collected by Dr. John Anderson in the Mergui 

 Archipelago. 



In the Challenger report on tho myzostomes published in 1887 Prof. Ludwig "^ on 

 Oral!' mentioned Antedon tuberculata from station 174 as a host for myzostomes, 

 The name, supplied by Carpenter, appears as a nomen nudum. 



In the Challenger report on the comatulids published in 1SSS Carpenter described 

 Ant,, Imi tuberculata as a new species. He said it has many points of resemblance 

 with spicata, and he suspected that it might prove to be a synonym of the latter. 



Carpenter did not discuss spicata in detail in the Challenger report, as it was not 

 taken by the expedition, but he inserted it in the key to the species of the Palmata 

 group, including it with tuberculata and indica in a special section set apart by the 

 possession of II Br and IlIBr series, and sometimes additional division scries, In- 

 having the division scries free laterally, and by having P., stiff and stylifonn, with 12 Is
