88 CRUSTACEA MALACOSTRACA. 



Occurrence. The "Ingolf" has only twice taken this species.

On the west coast of Greenland it is known from Karajok Fjord, ca. 70 20' N. L. (Vanhoffen) 

 and in Malac. Groenl. I have mentioned various localities in the region from ca. 70 to 64 I / 3 ' N. L,. It 

 was taken by the "Thor" a number of times at Iceland, namely, from the north-west coast in Patrik 

 Fjord, from the north coast in 0fjord and Skjalfandi, from the east coast in Rode Fjord; it is present 

 also from Seydis Fjord on the same coast, taken with the previous species by Hallas; Ostenfeld has 

 it from a spot south-west of Iceland. In the East Greenland waters it has only once been taken, at 

 ca. 74 20' N. L., 15 W. L. (Buchholz). 



Distribution. This species is further known from localities along both sides of Scotland 

 (Norman). It was taken by the "Thor" several miles west of St. Kilda and twice in the Skagerak 

 due south of Norway at 57 52' N. L. It was founded on specimens from the Christiania Fjord, and 

 Sars states that he has taken it "now and then" on the west coast of Norway, but does not give the 

 northern limits. 



We know at present no more of the distribution of this species, which is probably much greater. 

 We may believe that the gaps are partly due to its having been sometimes confused with or not 

 separated from the previous species.
