In 1900 Bosshard described the minute structure of the articulations, Russo traced 

 the origin of the sexual elements, and Giesbrecht gave a monographic account of a 

 curious parasitic copepod which had previously been found on A. adriatica by Rosoll 

 (1888). In 1901 Przibram published the results of his studies on the regeneration of 

 this species, Riggenbach discussed the autotomy, Russo contributed additional informa- 

 tion regarding the primitive gonad and the primitive stone canal, Kelly worked out the 

 chemical composition of the skeleton, Pruvot gave new records for various localities on 

 the eastern Spanish coast, and Giesbrecht described a new copepod parasitic in the in- 

 testinal canal. In 1902 Buller described the fertilization of the eggs, and W. S. Marshall 

 the male gonopores. In 1904 Ludwig discussed the retention of the eggs on the pin- 

 nules of the females, and Grieg compared mediterranea in detail with related species. 

 In 1905 Godlewski gave the results of his experiments in hybridizing this species with 

 echinoids, Minckert published a long account of the regeneration, first indicating the 

 way in which comatulids with more than 10 arms pass from the young 10-armed to the 

 adult niultibrachiate stage, and Bassani recorded this form as a fossil. In 1906 Lo 

 Bianco described the effect on the comatulids in the Bay of Naples of the rain of cinders 

 from the eruption of Vesuvius in April of that year, and there were further contributions 

 by Przibram on regeneration and by Bassani. Chadwick's detailed account (1907) of 

 the early stages of Antedon was based upon material of this species sent to him from 

 Naples. In 1908 August Reichensperger described certain glandular structures, 

 and Aranda y Millan recorded this species from various localities on the Spanish coast. 

 In 1910 Koehler mentioned this form as represented in the collections of the Travailleur 

 or Talisman, and Prof. Charles A. Kofoid published the first photograph of it from living 

 examples, taken in the aquarium of the Naples station. 



In 1911 Cotronei and Schaxel described the finer structure of the oocyte, and 

 Bohn certain reactions to physical stimuli. The early development was considered 

 by Mortensen in 1920 in connection with his work on other comatulids, and the meta- 

 morphosis was studied by Runnstrom (1930). 



Koehler, in 1921 and 1927, gave details of the distribution of the species and 

 Tortonese, in several papers from 1935 onwards, provided further instances of its oc- 

 currence, especially in the Ligurian and Ionian Seas, at Rhodes in the Aegean, in the 

 vicinity of Istanbul and along the coast of Israel. He also described the variations 

 of the color in life. Other new localities were provided by Rivera, 1934 (Majorca), 

 Mortensen and Steuer, 1937 (Alexandria), Ranson, 1925 and Cherbonnier, 1956 

 (Tunisia), though some of the latter might be referable to A. bifida moroccana.
