almost their whole length ; tlie sense organ in the inner ramus is moderately small, bnt distinct. The 

 telson has almost the same form as in Parrryf/irops ahyssicoln (i. (). vS.; it is moderately sliort, reaching 

 scarcely behind the centre of the inner ramus. The lateral margins are convex along the proximal 

 third of their length, distinctly concave and converging considerably backwards in their distal two- 

 thirds; the transverse terminal margin (fig. 10) is very short with .\ very long spines, the outer pair 

 of which is shorter and a little thinner than the inner (one .spine of the inner pair is lost and the 

 other also for a smaller or greater part broken off); the distal part of the lateral margin has 5 small 

 spines. (The hindmost pair of marsupial lamelkc are fairly small, evidently not fully developed; the 

 lamella: of the sixth pair of tlioracic legs are very small, and there are none from the fifth pair). — 

 Length from rostrum to end of telson 17-5 mm. 



The specimen preserved in formalin was of a dark gre\ish brown colour when received. 



Locality. The specimen described was taken by the "Thor" on Jul\- 11"' 1904 at the fol- 

 lowing place: 



South of Iceland: 6i'"3o'N. L., i7°o8'W. L., Young-fi.sh trawl with iSoo meters wire out. 



Distribution. According to a kind letter from W. M. Tattersall a specimen measuring 

 25 mm. in length was captured near the middle of June 1906 at 49° 27' N. L., i3°33'W. L. in the young- 

 fish trawl with 2800 m. of wire out; the depth of sea was 2600 m.

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

 South of Iceland: 63° 46' N. L., 22° 56' W. L., 70 fm.; large number of specimens. 



— - — 63° 15' — 22° 23' — 114 — 172 fm.; 8 spec. 



— - — 63° 18' — 21° 30' — 94 fm.; 15 spec. 



Distribution. The "Thor" has taken it north-east of the Shetlands, 85 fm. and in the North 

 Sea ea.st of Scotland, 47 fm. It is noted from Shetland, 40—60 fm. (Nornuiu), Fair Island, 60—80 fm. 

 (Th. Scott), from .several places on the east coast of Scotland (Norman, Th. Scott), from the Iri.sh Sea 

 (Holt & Tattersall) and west coast of Ireland, 80—293 fm. (Norman, Holt & Tattersall). Further, it 

 has twice been taken in the Skager Rak at some distance from Jutland in 49 and 70 fm. (Metzger, 

 Meinert). In Norway it is distributed from Christiania Fjord to West Finmark, usually in depths from 

 80 to 2CX) fm., bnt in 30—40 fm. in the inner parts of Christiania Fjord.

Occurrence. The "Ingolf" has not taken this species and it has not been brought home by 

 any Dane from the region in (piestion here, so that it is oulv included from the literature.
