These specimens were also submitted to P. H. Carpenter, and in 1890 his report 

 upon them appeared. Kef erring to them under the designation of Antedon, sp. nov., 

 he said that he believed them to represent a new species, but remarked that this may 

 turn out to be only a strongly marked variety of A. pumila (A. loveni). He intended 

 to draw up a diagnosis of this new form, but was never able to do this. 



In 1902 Sayce recorded specimens of loveni (as Antedon pumila) from the entrance 

 to Port Phillip in 11 to 16 meters. In all probability these were mostly or entirely of 

 this species, though I (A.H.C.) have given him the benefit of the doubt and entered 

 them under loveni which, unless a specimen in the British Museum is erroneously 

 labeled, also occurs there. 



When I examined the magnificent collection of comatulids belonging to the Aus- 

 tralian Museum I found nearly 800 specimens of Antedon loveni from various localities 

 in it, and with them several examples of a species which, though allied to it, was quite 

 distinct and showed no evidence of intergradation. This I assumed was the Antedon, 

 sp. nov., referred to by P. H. Carpenter in 1890, and in 1910 I described it, on the basis 

 of 5 specimens from Port Jackson, New South Wales, under the name of Compsometra 

 lacertosa. 



Shortly after this paper was published I visited the British Museum and was 

 greatly surprised to find that the types of Bell's Antedon incommoda included two speci- 

 mens of the form I had just described and one of Ptilometra macronema, but none of 

 Antedon pumila (loveni) in the synonymy of which he had unhesitatingly placed it. I 

 was fortunately able to make the situation clear in my memoir on the recent crinoids of 

 Australia in 1911. 



In 1911, 1 published a detailed discussion of the comatulids of Australia based upon 

 the collections made by the Hamburg Southwest Australian Expedition, under Drs. W. 

 Michaelsen and R. Hartmeyer, in 1905, in which this species was recorded from two 

 new localities. 



In 1916, Dr. H. L. Clark recorded it from Flinders Island, where it had been 

 dredged by the Endeavour. 



In 1928, Dr. H. L. Clark named two small specimens in the South Australian 

 Museum Compsometra incommoda. Their locality was unfortunately unknown The 

 larger had arms about 25 mm. long and XXVIII cirri. In the smaller the cirri were 

 only XX, with about 10 segments. 



In 1938, Dr. Clark recorded this species from a number of localities in southwestern 

 Australia, extending the range northwards as far as Geraldton (north of Fremantle). 



In 1946, he queried the occurrence of the species in Port Jackson. 



[NOTE BY A.M.C.] Following Gislen's synonymy of 1955, this species is now 

 referred back to Antedon.

Diagnostic features. This subspecies differs from incommoda incommoda only in 

 the relatively smaller dorsal pole of the centrodorsal, of which the center may be very 

 slightly convex. The eleven specimens have the dorsal pole from 0.4 to 0.9 mm, in 

 diameter, averaging 0.7 mm. The sides of the centrodorsal bearing the cirri are more
