PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 177 



Zoological Record noted the crinoidlike form of the organism and remarked that it was 

 doubtful whether it was a sponge. 



In 1882 Professor F. Jeffrey Bell in a list of names of comatulids included Antedon 

 loveni followed by a so-called specific formula, but with no other data; this specific 

 formula was modified by P. H. Carpenter in the following year. 



In the Alert report published in 1884 Professor Bell described this species in de- 

 tail and figured it under the name of Antedon pumila, transferring the original name 

 loveni to the species he had listed as Antedon insignis in 1882. The description given 

 by Bell in the Alert report is deceptive, for the number of cirrus segments is too small, 

 and their shape is inaccurately described, and furthermore P 2 is said to be longer than 

 PI, and on the figure PI is represented as arising from the first brachial. On plate 10 

 there are two figures lettered "B"; the present species is the lower figure "B", the upper 

 being an error for "C" and representing Colobometra perspinosa, the A. loveni 

 of this report, which is the A. insignis, not the A. loveni, of the list published in 1882. 



In 1887 von Graff, on the authority of P. H. Carpenter, explained the transference 

 of the name loveni by Bell from this species to Colobometra perspinosa (the Antedon 

 insignis of Bell, 1882) and Carpenter himself discussed it in the following year. 



In 1888 Bell described Antedon incommoda (see p. 161), and in 1889 he discovered 

 that he had erred in describing P] in A. pumila as shorter than P 2 . But in correcting 

 this error he made another, for he reduced incommoda to the synonymy of pumila 

 whereas in reality the two represent distinct species. 



In 1890 Whitelegge published an account of its local occurrence at the same tune 

 correcting Bell's error regarding the relative length of PI and P 2 , Ramsay recorded it 

 from Port Jackson and P. H. Carpenter from Port Phillip. 



In 1902 Sayce again recorded it from Port Phillip, and in 1911 the present author 

 listed it from several new localities. 



In 1938 Dr. H. L. Clark noted that 79 specimens were taken near Middle Head, 

 Port Jackson, so the species is evidently very abundant there. 



Miss Elizabeth Pope, 1943, found A. loveni on the underside of rocks in the sub- 

 littoral of Long Reef, New South Wales, when making an ecological survey of the area. 



In 1946, Dr. Clark commented that there were no reliable records of the species from 

 south of Port Jackson or north of Port Stephens, the Claremont Island and Port Phillip 

 records needing confirmation. (The Claremont Island record is here considered by 

 A. H. Clark to be of Antedon iris). 



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

 referred back to Antedon.

Diagnostic features. The centrodorsal is flattened hemispherical, with about 

 XXX cirri in three crowded marginal rows; none of the 10 to 12 cirrus segments are 

 more than twice as long as their median width, the antepenultimate is distinctly longer 

 than wide and the distal part of the cirrus is markedly expanded dorsoventrally; in the 

 type PI is 3 mm. long, with about 20 short segments; P z is 1.7 mm. long, with 12 seg- 

 ments; and P 3 is 2 mm. long, with about 13 segments; the following pinnules are like
