Mr. Thomas Edward sent me many years ago a specimen 

 to determine from the Moray Firth. I have taken it at 

 Shetland, and received from the late Mr. A. Hancock a fine 

 example procured by him from the fishing-boats at Whitburn, 

 Co. Durham.

A specimen of this species was sent to me for determination 

 by J\Ir. J. Duncan Matthews. It had been taken in October 

 1886 from a large sliark caught entangled in lines about 

 8 miles off Stonehaven, Scotland (see Mr. Matthews's record 

 of it, Ann. & Mag. Nat. Hist. ser. 5, vol. xx. 1887, p. 444). 

 A co-type specimen from Greenland, given me by Dr. LUtken, 

 is in my collection.
