POLYCMTA—BENHAM.

Genus Thelepus Leuckart. 
Thelepus setosus Quatrefages. 
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. 
Thelepus mdntoshi Grube (1877), p. 544. 
Thelepus spectabilis Ehlers (1897), p. 133, and his later works. 
Thelepus spectabilis Gravier (1906), p. 53. 
Thelepus setosus Fauvel (1916), p. 466 (for full list of synonyms). 
This Terebellid, which, as will be seen, has already been described from the 
subantarctie 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 l’hemisphere sud ne peut etre en rien differencie du Thelepus setosus de 
la Manche.” 
I can now add another locality, extending its range to Maccpiarie 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.
