THFS species appears to agree with Lilljeborg's description 

 of Leucothoe norvegica , chiefly in the formation of the propodos 

 of the second pair of gnathopoda. 



The hand is large, and armed with a strong sharp tooth 

 that projects from near the middle of the lower or posterior 

 margin, the apex of which reaches to a line with the palm, 

 from which it is separated by a deep excavation, the anterior 

 margin of which is directed in a line parallel with the anterior 

 margin of the propodos. The palm is straight, furnished 

 with five small broadly based denticles. The dactylos reaches 

 beyond the palm, but does not extend to the extremity of the 

 thumb-like tooth of the hand. 



This species was taken near Banff by Mr. Edward.
