In March, 1880, a porbeagle was taken at Wick, and 

 Mr. Reid wrote me: " Our fishermen caught a fine 

 specimen of this shark last week in their nets ; it 

 measured T^ft. in length ; there was nothing in its

 shark in my museum.

 British coast : it is called Sea-fox from the form of 

 the tail, which is very remarkable, the lower lobe being 

 very small, and tlie upper exceedingly long, curving up- 

 wards, and resembling the blade of a scythe.
