Range: This species has been definitely recorded from the Siberian polar 

 sea, as far east as long. 170 17' E., westward to Spitzbergen; but is not known 

 in Jan May en and East Greenland; it is definitely recorded from West Greenland 

 and various localities in arctic North America between Labrador on the east 

 coast and Bristol bay, Alaska, on the west coast. 



This species was only taken at one station by the Canadian Arctic Expedi- 

 tion; namely, 



Station 27s. Off Collinson point, Alaska, October 2-7, 1915. 1 adult and 

 1 young specimen. 



Mr. Johansen's field notes cited above (Mesidotea entomon (Linn.) of 

 Stations 27, 28) may apply to this species also. 



The type locality of this species is given by Kr<yer (1846) as: Julianehaab, 

 Greenland, collected in 1840; in his description of the new species he directs 

 attention to the fact that in 1838, in a discussion of Greenland Amphipoda he 

 commented on Idothea from the Polar sea which he believed distinct from 

 Mesidotea entomon, but refrained from describing for lack of material.

 in depths from 21 down to about 173 fathoms, temperature from slightly above
