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

 the orio-in of the sexual elements, and Giesbrccht gave a monographic account of a 

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

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

 this species, Riggenbach discussed the autotoniy, Kusso 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 Giesbrccht described a new copepod parasitic in the in- 

 testinal canal. In 1902 Duller described the fertihzation of the eggs, and W. S. Marshall 

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

 nules of tlie 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, fu-st indicating the 

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

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

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

 from tlie 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 Rcichensperger described certain glandular structures, 

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

 In 1910 Koehlcr mentioned this form as represented in the collections of the Tramilleur 

 or Talisman, and Prof. Charles A. Kofoid published the fu'st photograph of it fromhving 

 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 coraatulids, and the meta- 

 morphosis was studied by Runnstrom (19.30). 



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 

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

 of the color in life. Other new localities were pro^^ded 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.
