Rare on the southern coast, but, according to Mr. Neill, not uncommon in the North of Scotland, entering the Frith of Forth almost every Autumn in considerable shoals. Mr. Rackett's specimen was taken near the Isle of Portland in Dorsetshire. This species derives its English name of Skipper from its habit of leaping out of the water, and passing over a considerable space (Mr. Couch says thirty or forty feet) before returning to that element. It is not noticed either by Linnseus, Gmelin, or Bloch.
