Hob. This species has been taken by Mr. Thomas Scott on 

 both sides of Scotland — on the west in Loch Fyne, on the east 

 in the Moray Firth and Firth of Forth. 



Distrib. In Norway I have dredged it in the Hardanger 

 Fiord, off Lervig, in 150-180 fath. ; and in East Finmark in 

 110-125 fath. in the Varanger Fiord, and in Klosterelv Fiord 

 in shallow water. Other localities are : — off Reykjavik, Ice- 

 land {G. O. Sars), Denmark {Meinert), Greenland {Hansen). 



Hansen (31) describes and figures a Greenland Lepto- 

 gnathia which he considers to be L. longiremis of Lilljeborg, 

 but doubtfully refers to it the L. longiremis of Sars. The 

 Greenland form has the hand of the first gnathopod less 

 robust and without the characteristic serration of the outer 

 margin of the finger, and the uropods three-jointed, the first 

 joint markedly longer than the rest of the limb, the terminal 

 joint minute.
