Ohlin gives it from East Greenland: 74° 35' N. L., 18° 15' W. L., 79 fm. 



Distribution. The .species, which was founded on specimens from Ma.s.sachusetts Bay and 

 Gulf of St. Lawrence in depths of 33 and 50—70 fm., has according to the literature an extensive 

 distribution. It has been taken on the west coast of Norway at ca. 671/3 N. h. and at several places 

 on its north coast (Bodo, Porsanger Fjord, Varanger Fjord) in 60—150 fm. (G. O. Sars). Further, it 

 was met with near the southern end of Spitzbergen in 146 fm., temp, -f- i-i° (G. O. Sars); finally, in 

 the Kara Sea, 64 fm. (Hansen). The bottom-temperature everywhere has been either negative or very 

 low positive. — Holt and Tattersall's determination of it from the west coast of Ireland rests, according 

 to information kindly sent by the authors, on a confusion of names with Paicrythrops obesa G. O. Sars.

 Occurrence. This species was only taken by the "Thor", which found it at the 5 following 

 localities within our area. 



West of Iceland: 65° 08' N. L., 28° 10' W. L., 1240 m.. Young-fish trawl, 800 m. wire out; i spec.

South-We.st of the Fseroes: 6o°oo'N.L., io°35'W.L., 1015 m., Young-fish trawl, 1000 m. wire out; i spec. 

 Distribution. The "Thor" has also taken this species twice west of the Hebrides in the 

 young-fish trawl with 1500 meters wire out. It was founded on a single specimen taken west of Ire- 

 land in a net sunk to the bottom, 382 fm. — All the 7 localities of the "Thor" show, that the .species 

 belongs to the mesoplankton, the young-fish trawl fishing in 180 to 450 fm. 



Remarks. This beautiful species is extremely easily recognised. An adult male measures 

 12-4 mm.

Occurrence. The species has only once been taken by the "Thor" at the following locality. 



South of Iceland: 63° 5' N. L., 20° 7' W. L., 295 fm.; several specimens. 



Distribution. The species occurs along the Norwegian coast from Christiania Fjord to 

 West Finmark, 50 — 300 fm. (G. O. Sars; Nordgaard). Further, it was taken west and south-west of 

 Ireland (Holt & Tattersall, who discuss its bathymetric occurrence in 1905). Lo Bianco gives it from 

 some places in the Mediterranean in depths of quite 500 to over 600 fm., but this determination until 

 further information is forthcoming must be regarded as uncertain.
