214 PSEUDOBONELLIA, A NEW ECHIUROID GENUS, 



We are aware of only one record of the occurrence of Bonellia 

 or Bonellia-like echiuroids on the Queensland coast, Hedley 

 (1906, p. 462) having stated that he saw Bonellia in abundance 

 in the lagoon in Masthead Islet, Capricorn Reefs. Only on one 

 occasion (August, 1917) have we succeeded in finding a few 

 specimens of a Bonellia-like worm in that locality, though 

 searched for on several occasions between 1912 and 1917. He 

 also made reference (1906, p. 462; 1915, p. 27) to the attempts of 

 tropical animals such as Bonellia to colonise the shores of New 

 South Wales while the Notonectian current floods the coast, 

 many such perishing when this warm stream swings off-shore. 

 This, no douht, is the explanation of the occasional presence of 

 a number of tropical invertebrates in Port Jackson. 



Haswell (1885, p. 331) reported the presence in Port Jackson 

 of a Bonellia which he identified as B. vividus (a misprint for 

 B. viridis, the Neapolitan species), mentioning, however, that 

 there were certain differences from that species in regard to the 

 reproductive organs. His specimen came from Neutral Bay. 

 Whitelegge (1889, p. 211) quoted the reference under Boyielliasp., 

 and added another locality in Sydney Harbour, viz., Mosman 

 Bay. Mr. Whitelegge informed us that he had obtained his from 

 under a stone at Sirius Cove, Mosman, during a low tide. 



Saville-Kent (1889, p. 230) reported that Bonellia was obtained 

 in abundance while dredging in the Cambridge Gulf, North-West 

 Australia, while Dakin (1916, p. 23) recorded the occurrence of a 

 green species on the Abrolhos Islands, the Swan Estuary, and 

 off Garden Island (near Fremantle) in South-Western Australia. 



Shipley (1899, p. 336) referred a small specimen found by 

 Willey in the Loyalty Islands to the species B. viridis, mention- 

 ing (p. 342) that the latter had noticed the same species in the 

 D'Entrecasteaux Group, British New Guinea. Sluiter (1902, 

 p. 50) expressed the opinion that a detailed examination of the 

 worms identified as B. viridis by Shipley and by Haswell would 

 probably show that the Pacific species was distinct. 



B. pumicea Sluiter (1891, p. Ill) occurs in the Dutch East 

 Indies, while from Southern Japanese waters Ikeda(1904, 1907) 

 has identified B. minor Marion, B. miyajimai Ikeda, and B,
