I am indebted to Dr. E. L. Moss (late surgeon H.M.S. 

 ; Alert '), who served with the Arctic Expedition, for the 

 notice and determination of this Sagitta. He informs me 

 that it was common in Melville Bay and Smith Sound. The 

 most northern specimens were captured by him in Bessels' 

 Bay, lat. 81 7 r N. [This species has a very extensive range 

 from the British shores northward, southward and westward.]
