SOME NOTES ON THE SCOTTISH CRANGONID^ 231 



Sabinea septemcarinata, Sabine. — One of the principal points 

 of difference between Sabinea and Crangon is that in the former the 

 second pair of thoracic legs are not chelate but simple. The only 

 known British example of this species was captured in 1861 by the 

 Rev. A. M. Norman sixty miles east of Shetland, at a depth of eighty 

 to ninety fathoms. This is the only species among those enumerated 

 here that has peculiarly arctic distribution ; and probably when the 

 seas around the Shetland Islands come to be more thoroughly 

 examined other arctic forms may be obtained.
