POLYCHiETA— BENHAM. 91 



Genus Thelepus Leuckart. 

 Thelepus setosus Quatrefage^. 

 Phenacia setosa Quatrefages (1865), vol. II, p. 376. 

 Neottis spectabilis Verrill (1875). 

 Neottis antarctica Mcintosh (1876), p. 321; (1879), p. 261, pi. XV, figs. 14, 15; 



(1885), p. 472, pi. LII, fig. 1. 

 TJidepus mdntoshi Grube (1877), p. 544. 

 Tlielefus spectabilis Ehlers (1897), p. 133, and his later works. 

 Tlielepus spectahiUs Gravier (1906), p. 53. 

 Thelepus setosus Fauvel ( 1916), p. 466 (for full list of synonyms). 



This Terebellid, which, as vaW be seen, has already been described from the 

 subantarctic under a variety of names, has now been identified by Fauvel with the 

 European species. He had under his eyes specimens from the Falkland Islands and 

 examples from the Straits of Dover, and arrives at the conclusion — "le Thelepus 

 spectabilis de I'hemisphere sud ne pent etre en rien differencie du TMepus setosus de 

 la Manche." 



I can now add another locality, extending its range to Macquarie Island. Some 

 of these, which were well preserved, were from Garden Bay, others from the North End ; 

 some were found attached to rocks below low water, others were from sand under stones 

 at low water. 



Distribution. — Strait of Dover, coast of Ireland: Kerguelen (Grube, Mcintosh); 

 Bouvet Island, Marion Island (Mcintosh); Fuegia, South Chili (Ehlers); 

 Port Charcot, He Booth Wandel (Gravier): Falkland Islands (Pratt, Fauvel); 

 S.W. Australia (Fauvel (1917), p. 268). 



Thelepus antarcticus Kinberg. 

 Kinberg(1866), p. 345. 

 Willey (1902), p. 278, pi. XLV, fig. 6. 

 Ehlers (1901), p. 210 (repeats Kinberg's record). 



The brief diagnosis given by Kinberg is scarcely sufficient to enable one to 

 visualise the species, but the few facts he does give agree with those exhibited by the 

 specimens in this collection, and I have no doubt that they belong to that species which 

 has hitherto been recorded, since 1866, only by Willey. 



In view of the enormous numbers that were obtained by the expedition (in one 

 jar there are more than one hundred individuals), it is very remarkable that none of the 

 recent expeditions to the Southern seas has met with it. ;'
