Eucalanus acus, Farran. This species was widely distributed throughout the region 

 but rarely abundant. It occurred both in the cold Antarctic surface layer and in the 

 warmer intermediate layer. It was first described by Farran (1929) in his report on the 

 collections of the Terra Nova Expedition. He found it " taken in considerable numbers 

 from the surface to 80 m. in a limited area south of New Zealand from 51 22' S to 6i° 

 18' S."
