POLYCHiETA— BENHAM. 19 



2. ]\Iacquarie Island. 

 This island has not hitherto l)een explored for Polychaeta, but thanks to the 

 industry and care of Mr. H. Hamilton during the nearly two years he sojoiuuied here, 

 I can put on record fifteen species of which three are new : Luiitbricanereis macquariensis, 

 Sflwerodorum spissum and Polycirrus hmniltoni. All the other species are t\'picallv 

 sub-antarctic in character, and have been recorded either from the southern outliers of 

 New Zealand or from the Kerguelen or Falkland Islands. They were all collected in 

 rock pools or under stones or rocks along the shore.

3. IMaeia Island, Tasmania. 

 Five species were obtained in the two trawls put down by Professor Flynn. 

 Of these one is new, and belongs to a Polynoid genus, Hololepidella, established by 

 Willey for a Ceylon species. Two of the other species obtained have already been 

 reported from the neighbourhood ; the remaining couple are widely distributed. 



Hololepidella flynni (fi'om 1,300 fathoms). 



Physfdidonotus rugosus (from 65 fathoms). 



Lcetmonice producta var. benthaliana (from 1,300 fathoms).
