History. This species was first brought to light by the British Antarctic Expedition 

 of 1901-04 in the Discovery under the leadership of Capt. Robert Falcon Scott, R.N. 

 It was originally described and figured in the reports of this expedition by Prof. F. 

 Jeffery Bell in 1908, who named it in honor of Dr. Edward Adrian Wilson, the surgeon 

 and naturalist to the Expedition. 



Additional information regarding the original specimens was published by myself 

 in 1913, and in 1915 I described in detail and figured the examples taken by the German 

 South Polar Expedition in the Gauss near Gaussberg in 1901-03, excepting for two 

 pentacrinoids which are described in vol. 1, part 2, pp. 557-559 of the present work. 



In 1917 Prof. Bell recorded it from three localities where it had been found by 

 the British Antarctic Expedition of 1910 in the Terra Nova. It was on this expedi- 

 tion that Capt. Scott and Dr. Wilson lost their lives. 



A single individual secured south of South America by the Swedish South Polar 

 Expedition of 1901-03 in the Antarctic under the leadership of Dr. Otto Nordenskjold 

 was recorded by Dr. Th. Mortensen hi 1918. 



Analyses of the inorganic constituents of the skeleton, determined from material 

 secured by the Gauss, were published by Prof. Frank W. Clarke and Dr. William C. 

 Wheeler in 1914, 1915, 1917, and 1922. 



The myzostomes found with the specimens collected by the Discovery were described 

 by Dr. Rudolf Ritter von Stummer-Traunfels in 1908, and those found with the 

 material from the Terra Nova Expedition were described by Mr. C. L. Boulenger 

 in 1916. 



In 1925 Dr. Mortensen recorded the species from the collections of Mr. Sten 

 Wallin in the Discovery Inlet, Ross Sea, in 550 meters. 



The whaler Bransfield took 10 specimens of Anthometra from a harpoon line when 

 hauling in a whale in the South Shetland Islands area. Grieg in 1929 gave some 

 notes on these. 



In 1937 my report on the crmoids of the Australasian Antarctic Expedition in 

 the Aurora was published, giving details of material from off Adelie Land and Queen 

 Mary Land on the antarctic continent.
