The Danish East-Greenland Expedition has, l8 / 9 1900 10 p. m. F. 346 at the surface near Kap Dan 

 (Tarsuak Fjord), taken a single adult female. 



Lundbeck has l8 / 5 1890 55°25 L. N. 29^ L.W. gathered 1 f?, 1 y? (IV). 



The S/S Thor has, outside the Ingolf area south west of the Faeroes, taken the species at four 

 stations, but at the two only a few adult females.

Distribution. This species has been recorded from the Mediterranean, and from the Atlantic 

 as far north as 55 L. N. io° L. W.; it has been taken by the Monaco and by the Gauss Expeditions 

 in the Mid and South Atlantic; by the Gauss it has been taken at 45 L. S. 35 L. E. south of the Cape. 

 It was not taken by the Siboga, but Esterly records it from the Californian Bay, and based on some- 

 what too small material he draws the following conclusion (191 2 p. 311) "evidently, the species moves 

 upwards at night if the numbers taken then as compared with those during the day can be taken as 

 representative of the whole population". 



I think we are right in regarding this species as in the main an Atlantic one, which frequents 

 the intermedial strata, but occasionally is found from the surface down to a depth of about 1000 meters. 



Remarks. The described species is certainly identical with that described by Giesbrecht, in 

 spite of the larger size, the wanting seta of Le 2 of maxillulae and the structure of the spines in the 

 Basp. II pes IV. The male, which CI eve refers to this species, is possibly identical with mine; his des- 

 cription is too incomplete to settle the question at present. I think that Giesbrecht is right in refer- 

 ring the small Atlantic specimens of E. Hessii Brady to this species, the bigger ones may perhaps be 

 identical with E. rostromagna Wolf.
