This handsome iridescent copper-coloured Eunicid, with white tentacles and 

 cirri, lives in a thin-walled tube below stones, and often wedged among rocks at 

 low water.

The synonymy of this worm is given fully by Ehlers in his " Die Borstenwurmer," 

 p. 297, whom I have followed in the use of the generic name. 



The single individual which came into my hands has the usual transparent 

 horn-coloured tube, incomplete at its lower end, measuring 40 mm. by 2-5 mm. 

 At about half-way along its length there is a thickened ring or " node " (Uke that 

 in a bamboo rod), and the distal portion starts with a slightly less diameter ; this 

 is apparently an indication of the cessation of growth. The enclosed animal is in- 

 complete posteriorly. 



Locality. — ^Bounty Islands ; (Captain Bollons). 



Distribution. — This species has already been recorded from the New Zealand 

 coast by Ehlers, from specimens sent him by myself. Ehlers writes (Neuseel. Annel., 

 ii, p. 12), " This species, widely distributed outside the arctic and antarctic areas, 

 has here [New Zealand] probably its most southern limit." This new locality ex- 

 tends this limit some distance eastward, but the Bounty Islands are at about the 

 same latitude as the southernmost portion of New Zealand.

A single individual of this very widely distributed species was obtained.
