The species is recorded from Karajok Fjord, ca. 70° 20' N. L., on the west coast of (Greenland 

 (Vanhoffen), from Davis Straits at 62° 06' N. L., 55° 56' W. L. (Norman) and from the waters south-west 

 of Greenland at 59" N. L. 51° W. L. (Hansen). It has many times been taken by varions expeditions, 

 especial!)' b\- the "Thor" in 1904, in the waters round Iceland as also to the west and south of the 

 Foeroes. It was taken at Jan Mayen by the 2"'' Amdrup Expedition and at 7372"' N. L., 4'W. L.; finally 

 by the Ryder Expedition at East Greenland at 70° 22' N. L. 



Distribution. The .species is known from the Fa:roe Channel (Norman), vScotland (Norman), 

 northern part of North Sea and west coast of Ireland (Holt & Tattersall). It is even noted from the 

 Skager Rak (Intern. Explor.). G. (). Sars gives it from the west coast of Norway without indicating 

 the southern limit, from Varanger Fjord and from 4 stations between Norway and Jan Mayen. It is 

 also noted from Bear Island, from North-East Spitzbergen and north of Spitzbergen at 81° 20' N. h. 

 (Zimmcr); it was taken by the "Fram" much further to the north of Spitzbergen at 84— 84' ',° N. L.; 

 further, north-east of Franz Joseph Land at ca. 84'/,° N. D., 72° E. L., lastly at ca. 80° N. L., 124' E. L. 

 (G. O. Sars). It was taken on the German Plankton-FZxpedition not only in the direct line from the 

 north point of Scotland to Cape Farewell, but also several times on the line from 60° N. L., 42" W. L. 

 to near the southernmost corner of Newfoundland ((_)rtmann). 



It was taken three times b\' the Plankton-Expedition in the c\linder net, thus near the sur- 

 face, bv the "Ingolf" twice near the surface and 15 times in depths between 100 and o fm. As a 

 result of these numerous catches we are justified in concluding that the species is found as a rule in 

 the upper water layers, either near the surface or at any rate not deeper than 100 fm. under this. 



According to Holt & Tattersall the specimens from the west coast of Ireland differ in various 

 small details from the Norwegian specimcn.s, but the differences are so small that the authors do not 

 even set u]3 the Irish form — which the\- think resembles greatly the F;eroe specimens — as a \-ariety. 

 Their observations with regard to the batliymctric occurrence of the Iri.sh sjiecimeus do not agree, 

 howe\er, with the conclusions I have considered mxself justified in drawing above.

 Occurrence. This .species was not taken by the "Ingolf, but the Copenhagen Museum 

 possesses some s])ecimens from 4 places l\ing within our area.
