The type of the species, no mm. in total length, is from off the Ross Barrier at a 

 depth of 562 metres. The above description is based upon a large number of specimens, 

 up to 180 mm. in total length, obtained by the 'Terra Nova', 'Discovery' and the 

 B.A.N.Z. Antarctic Research Expedition. The species seems to occur mainly in fairly 

 deep water.
