In 1897 Ehlers, from a study of the original specimens, showed that G rube's 

 species is identical with that of Kinberg ; and in his account of the New Zealand Annelids 

 ( 1904) he further established, from an examination of the types, that Kinberg'p species 

 is synonymous with Schmarda's. He gave an extended and illustrated account of the 

 species, which is widely spread over the subantarctic area. It is evidently very common, 

 for the " Aurora " naturalists gathered some seventy specimens, varying in length 

 from 14 mm. up to 125 mm., the latter with a diameter of 12 mm. over the parapods. 



The worms are labelled as being " flesh coloured " in life as I know from 

 observation of our local specimens. In spirit, however, the dorsal surface becomes 

 a pale brown and the parapods usually white. 



The habitat extends from the shore-line, where 't seems to be most abundant, to a 

 depth of at least 157 fathoms, where it seems to attain its greatest size.

Genus EURYTHOE Kinberg. 



EURYTHOE COMPLANATA Pallas. 



E. pacifica Kinberg Mclntosh (1885), p. 27, pi. II, figs. 3, 4; pi. Ill, fig. 2; 



pi. II A, fig. 13; pi. Ill A, figs. 5-9. 

 E. complanata Ehlers (1908), p. 38. 



Ehlers* has shown that these two, as well as E. alcyonia Savigny, are identical, 

 and discusses the history of the species. Fauvel ( 1919, p. 348) gives a list of the literature. 



From the neighbourhood of Tasmania a young specimen was obtained measuring 

 11 mm. for 35 segments. 



The distribution of the species is very wide, as it seems to occur in all seas and 

 oceans.
